bike wont start

left the bike on charge looks like it has taken one
my batt is ytz 14s I ride every day
I will check voltage before and after the start I dont think I still have warranty I bought it in the spring of 07 so its been just over 1yr
the bike is an 07

hi guys the bike has been put away for the winter and battery conected to a trickle charge i un-wraped her this morning put the key in to wake her up and she starts having an epelectic fit?? the rev counter wont do its cycle, the pump doesnt make its little noize and the dash flashes like an indicator???? the middle relay under the seat is ticking like fook aswell
the batery is showing full on the trickle charge

any help please

ignore the trickle charge readout, get a multimeter on and tell us the reading

Bat is reading 13.73
With ignition on 6.35
?????????

And weeksy them cans wernt all they were cracked up to be the cones are split/holes in them bit grubby and lots of marks around the carbon straps but did get a £50 refund so not all bad

I think your battery has gone resistive, if you can get acces to another battery, any kind of battery ( at least the same amp range, or even your car battery ) disconect your batt and try with another one, I had a very similar problem, trickle said it was ok, DMM said it went to 7vdc when trying to crank, unplugged the original, got my car battery outside the SD, got my jumper cables, and it turned on just fine.......so I got me a new batt and it now starts just fine.....resistive battery, bought a new AGM cell for under $100 usd on ebay and called it a day

Dont know if this is the case??? The bike goes nuts flashing and relays tick before I try and turn the engine over !! Its as if it maybe shorting or something? ??? Just cant get my head around it

check with your multimeter, voltage all off, voltage when you open the switch, don´t try to turn it, just open switch, BUT check up where the fuses are, don`t check it straight off the battery post......if voltage drops when you open the switch below 11vdc...you either got a bad ground, lose wire....or messed up batt, gotta check this step by step, and do let us know how it goes

EDIT : flashing??? does you SD have an alarm system??

Thanks evelworx no alarm fitted, im thinking the same about a bad earth im gonna have a good look in the morning

right then iv pulled the white fuel pump plug and everything stopped flashing and stayed on as normal
but wont turnover i know the pump wont run but should the starter try and wind up????

hair dryer on what weeksy??? the plug is dry as a bone

starting to get fooked right off now no moisture in any of the plugs ,, when pump is disconected all dash lights and spedo comes on as normal (but rev counter does not do its sweep)????? try and start the bike and the relays under the seat and the one by the battery go nuts the dash and lights flash aswell ??? put a multimeter across the bat and get 13+ but when i go to start the bike i get 5-6 ,, iv tryed the same on the starter motor and cant seem to get any voltage ??? dont know weather its coz iv got the pump disconected??? SOMEONE PLEASE HELP MY HEAD IS FALLING OFFFF

ok, then how about we start all over again.....

Undo the bellypan and leave all the wires exposed, make shure they are not kinked by anything....

trace your batt cables, does the NEG from battery, go all the way to the frame? or where does it go?

if the NEG goes to the frame, then, if you bypass the starter relay, does the starter turn over? do you know how to bypass it to test it? let´s check if the starter works, if when you try to bypass it, batt goes low and lotsa sparks fly, then starter is somehow fooked.....short circuiting and sending it all to hell.....

that´s why we need to check it first and foremost, before going to the next step

EDIT : if you need to, I can undo my SD and make a video on how to test and bypass the starter in order to diagnose it, don´t dispair, we´ll get to the bottom of this

hi evilworkz there is 2 cables from the earth side of the batt 1 goes to the heat sunk thing mounted above the batt and the other goes straight to the caseing of the starter??? and im not sure about how to bypass the relay ?????
thanks buddy

yep nothing only sparks but i dont know why my rev counter is not doing its sweep when i put the ignition on

do you have access to a car battery and jumper cables? if so....place the car battery´s negative to the SD´s chasis, then, disconecte the cable that comes from the STARTER all the way down to the battery.......and touch the car battery´s positive lead with the starter cable......do this, without opening the SD´s switch, we just want to make shure the STARTER is working

IF the starter does not turn.....that starter is gone and when it short circuits it send all to hell....you need a new starter

IF the starter turns the engine, then we´re one step closer to completion....reconect the Starter´s cable back to the SD, unplug the SD´s original battery positive( from the battery itself ), AND LET THE SD SIT WITHOUT ANY POWER FOR AT LEAST 20 MIN....after the 20 min, CHECK ALL THE FUSES, top and bottom.......now hook up the SD´s original positive lead to the car battery´s positive lead via the jumper cables ( we are bypassing the original batt )......open the SD´s switch, all should light up, try to turn it on......

let us know what happens

right then evilworkz iv done all that. the starter turns over (but struggles) with both batts when conected direct and when conecting the car batt through the jump leads to the cables (through the starter relay) it does the same ie dash comes on but rev counter doesnt sweep and when you push the starter all relays go nuts and dash flickers??????
where on the bike is the main earth to frame?????

I had the starter solenoid go on my SD was misfiring and then similar symptoms.


Search "solenoid" and "Superdan" as author a few threads come up, might be of help.

There are a couple for sale on eBay us the part in on about.

the main ground is under the radiator´s overflow bowl, on the right side of the SD, right side if you where sitting on it, it´s very near the starter, follow the cable from the batt up

if you still have your car battery there, conect an extra ground from the batt to the chasis and re check, also, check the ground that goes to the main wiring, let me take some pics to help you out as to where the grounds on the SD are

This is the main ground that comes from the battery, it´s on the right side of the SD

this is where the other main ground is, that goes to the main harness, you gotta remove the panels to get to it :



this is a close up of it :



remove all grounds, clean them, check if the connectors are not broken or fractured, also clean the ground down by the regulator, the one that goes from the battery to the regulator, and from the regulator it goes up to the main ground, check and clean them all, hope that works

Sounds pretty obvious to me that your trickle charger has fried your battery and the car battery you are trying to use is not much better off.

Buy a new battery for your bike and you should be fine.

update i think the starter or something is fooked i tryed to jump it off the car and nothing then i tryed straight to the starter and it bearly turns over am i right in saying to take the starter off i just take the 2 bolts with earth straps off????

right starter is off and spins up (without load) ??????
there is something putting the engine under stress i think?????

i know its a bit of a pain , but have you got a mate that can help you bump start it

ill try the bump when its dry and im feeling fit (there are no hills around my house lol
ive put the starter back on and pulled the spark plugs then tryed starting it .... it struggled for a bit (1 min) but slowly started freeing up????
could it be slightly seised??? really getting pissed off now

Extract from Wikipedia

"An idle starter solenoid can receive a large electric current from the motorbike battery and a small electric current from the ignition switch. When the ignition switch is turned on, a small electric current is sent through the starter solenoid. This causes the starter solenoid to close a pair of heavy contacts, thus relaying a large electric current through the starter motor, which in turn sets the engine in motion."

If your happy the battery is full/charged and the starter motor is only just turning over, this could well be issue which I stated earlier.

if your trying to jump start it with shitty jumper cables, well, no amount of nothing will make the starter turn....I also beleive what everyone is saying....electron flow problem....

the SD used to start fine before, didn´t it ?

superdan thanks but iv ruled out the solenoid/relay (i think) because im trying straight to the starter motor

put the plugs back in and got the same THE STARTER IS REALLY STRUGGLING (bearly turning) i do think the starter could be fooked but its never struggled before ??? is there any way of testing it????
evilworkz yes the bike started on the button every time up untill i put it away for the winter about 4 months ago???? i know u say its ground related and iv also thought that up untill now but the starter should turn over when power is direct to it ???? SHOULDNT IT?????

Can you not borrow a good battery from another bike? You don't need too install it etc,just get it wired up

it should turn over with leads on it , but you need a good earth on your jump leads which is sometimes hard to get on on something that has a lot of paint on

Sounds to me like you could be making a mountain out of a mole hill....

You say the bike started fine before storage. You stored bike with good working battery (AND starter motor) with battery tender hooked up. You pull bike outta storage and now won't start. Battery voltage reading wonky....

I don't know, maybe it's just me.....but I would replace the fooking battery.

Guys you cannot bump start a fuel injected bike.

I don't recommend trying to bump start the bike!

I tried it on mine once, down a steep hill, in second gear (to make the engine brake less significantly than in first gear), and when the bike was rolling about 25km/h i released the clutch and the rear wheel just locked up completely and I made about a 20 meter long black skid mark from the locked up tyre.

Change the damn battery

Right iv ordered a new battery (dont think it will make much difference) even tho it won't crank over with the plugs out and a good car battery conected but hey im open to opinion

Yeah weeksy I figured that mate I dont think its that but it cant hurt but try???

Should come charged but I have a charger anyhoo

Well after reading this post i went out to mine to start her up,the battery has been left on a trickle charger over the winter. Plenty of power but the engine would'nt turn over so i took the battery off and charged it with a proper battery charger,still it would'nt turn the bloody engine so i rigged it up to a big leisure battery and bingo first turn and she fires up.
I've ordered a new battery as it looks like the original is knackered even though it appears to be fully charged.Prices for batteries vary wildly from £59 to an OE from dealership £178 WTF? all were Yuasa YTZ 14s jobs. I hope a new battery solves your problem gfunkmc

I can't see how you could bump a FI bike with a completely dead battery. You need to turn the engine fast enough for the generator to create enough current to run the fuel pump, throttle bodies and ignition coils. Maybe it's possible but wouldn't be 2 turn over start that's for sure. The SD is a complete bitch to bump anyway. With a slipper fitted its impossible.

Just in case.

ok ill exept all the name calling IM A COCK IT WAS THE BATT
thanks for everyones help expesh evilworxz
but now more probs and a new post on fuel pump

Thanks weeksy I know sorry

It´s cool, glad we could help out, now let´s take a reading on the next problem

You might want to toss that trickle charger as well before it fries your new battery.
