Right. His bike Triumph 955i) has stopped charging the battery. We tested the rectifier and it wasnt working. We replaced that and its now putting 15V out of it... Problem is there is still no charging goin on!!!

So checked fuses, still nothing. Anyone got an idea? Ill have a good look at the wiring diagrams to see if there could be.

Cheers in advance for any help.

If you have the current flowing to the battery and it is reaching the battery terminal connection is the earth side properly connected as well.Check that the battery is actually accepting a charge,as it may have a duff plate and be completely knackered.
My battery died COMPLETELY while on holiday this year,nothing wrong with the system,just a dead battery. [955i with a seven year old battery]

I'd guess that too, unless you've tried it.
If the reg/rec was getting not working correctly before and now the new one has a good output but it's not charging then the battery seems the only thing left it my mind

Battery is good. Its been fully charged and its what the bike is running off as there is no power coming from the rec for some reason. I know this because we disconnected the the battery and the bike instantly died, which it shouldn't by my reckoning as the rectifier should run it. The rec is putting out power now we have replaced it, but its not reaching the battery. So basically there is some break between the rec and the battery.

Ill check the charge cct (checked out the wiring diagram) by taking out the charge fuse and testing the voltage. Obviously I should be getting between 14 and 15v there on the regulator side and about 12 on the battery side. So if not getting ~14 on the rec side then ill know there is a problem there. Im hoping that its just the fuse, none of them looked to have gone tbh but I guess I might have just missed it.

Ill keep this updated.

Not so, this happen'd to my Aprilia when I first got her.
after we jump started it, took the cables off and she died... jumped her again, and same again when one lead was disconnected...
new battery fitted, all singing and dancing and happy me when out for a ride with big grin on face.

also , did you check the voltage at the battery with the bike running... ie 15Volts or at the regulator ?
if at the battery with the engine running then your battery is kaput.

hope you get the problem sorted soonest.

Aye. OK we got a spare battery we can check...

its a truimph

To be fair its the first issue in 35k miles and its been ridden all year round. I dont consider it bad when my mates VFR750 had the same issue at less than 10k miles and that was a "magic never brake down honda" cough.

Has he sold that yet?!

Didn't the regrec like physically melt on that one too?

oops was gonna suggest that, thought you woulda tried a spare battery before trying it with no battery, let us know what happens

Ahhh. Well ive checked. The rec voltage is getting to the fuse. The fuse is fine... I had the fuse out and and the battery voltage dropped to 11.5v. put the fuse back in and it jumped to 12.5v. So the voltage is getting there and making a difference it seems.

Should it be able to run without the battery? Im just wondering if the rectifier needs a negative source? If it does then obviously no battery no work... Sigh.

We don't have a spare battery (thats any good) , well other than the one out of my bike I guess.

Yes he got rid of the bike that melted ha ha
