Multi meter reading of battery

Hey guys,

Continuing with my saga of Soft 32 Dat 101, I just got my new used (but supposedly good) Reg/Rec in the mail.

Shorai battery is still somwhere above the Atlantic as it seems.

I thought getting on with stuff as I found out the battery has marking of 11/12 which usually refers to the end of warranty which means it's about 1 year old, so it's new and seems weird that it'll be faulty.

So.. charged it up with a stupid charger so it was not topped as I calculated it needed 12 minutes and not more.

With old rectifier:

switch off - 12.3 V
Switch on - 11.9 or so
On starting it goes down to 9.45
idle - 13.8-14
above 2000 rpm it DECREASES to 13.3...

I'm like

Any thoughts before I go on to change for the "new" reg/rec? it's a bit of a shitty job to route these wires there and I'm not even sure it's bad.. Have no idea what and how to check.

Help!

Sound like the regulator to me. The decrease in voltage is likely due to the need for more power at high revs.
Have you checked for shorts across the three alternator windings?
I doubt that they are shorted since the voltage does go up when it is running.
12 volts is too low for a battery,btw.
I am sure when you get the new battery and install the regulator you will have it sorted.
GL!

Thanks.

I just spent about an HOUR! trying to unclip the brown connector that goes from the regulator to the alternator.

Still connected, I'm pissed as f*ck, feel like setting the bike on fire and let it melt. Honestly, I'm fed up with that piece of shit. It's all greased up, tried cleaning it with some WD40 and air preasure. Still, doesn't come loose. Of course the little clip that wan on the alternator connector side broke after 10 seconds.

After pulling in desperation, I think the middle cable came loose, of course, on the side of the alternator.

fook me, I just want don't feel like owning that piece of crap any longer.

Any ideas on how to free that shite before I go cut the wires and spend another day at some cheesy electronic shops looking for same connections?

I have a friend in Israel right now who might haul your bike here to me just to stop your misery.

I suggest taking a break and coming back later.
Those and all of the connectors on the bike are far from intuitive when it comes to removal. The big ass plug behind the coolant overflow is a perfect example.

Just chill out and come back with a fresh approach.

I used contact cleaner and even tri-chlor brake cleaner on my harnesses frequently and never saw any degradation of the wiring loom or connectors

Thanks mate, that's some useful info!

With some help of my dad (which is quite better in electronics then myself) we got it disconnected.
Seems that the heat had melted the connector that comes from the alternator, the middle cable is just fried and it's tip got glued to the R\R connector.

Gonna try and replace it with a new connector or just weld the wires together and put shrinks on them.

Though, after reading your friend's note I feel bad not going for the expensive mosfet R\R and maybe shrinks are not a good idea since I'll have to replace it soon enough..
