Its that damn reg issue again

[griffo117]

Hi all ive had this problem for a while now and ive done the repair and mod a few time as well but it keeps reoccuring with the regulator rectifier burning out ive done all the test from the stator etc and everything comes up good then a few months later i check the wiring and one yellow is burnt out

Sorry to hear that M8. Wish I could help,I'am sure someone with the knowledge will reply.

Connections are good and sealed so i dont know whats going on i might just have to put up with it cause im not getting rid of her for nothing

Have you metered the outputs from each alternator coil?
Try a MOSFET reg/rec.

anything can be fixed, just finding the cause is the problem here

Hi m8 pm me and we'll work it through.

essentially you either have a short from the reg that is working the diodes too hard, but not enough to blow a fuse e.g.high resistance short to the lights, or you might have a poor ground wire to between the mag and reg. There is only 5 wires in it.....3 are for dc power conversion, one out to the battery and one back to the ignition.

Are you buying new or second hand? Are you buying the exact reg? Do you have loads of extras......

The only thing which could under normal conditions drive too much load would be stacks of lights or motors..storms are lets say pretty weak on the old electronics fronts....but if you no accessories but haven't had teh bike long it would be cworth checking the main red and main yellow wires from the reg...

Try metering between the yellow and then the red wire The yellow that does not go back to the mag, and a "good earth to the battery - preferably a wire" with ignition on but don't start to see if there is a volage drop, then if you know how to do it check for current leaks, then start the bike. The red wire should go battery positive [eg same voltage as the battery under charge] but the yellow should be at least 13.5 volts. If not then you have a high resistance short loading the reg.

i do run my alarm as well as 1 other and i have checked the stator about 4 weeks ago just as a precaution and it was ok
im buying new regs even bought a r1 reg and done the conversion (that lasted 6 months as well)been to auto electric mobs and they just scratch their head
ill give what you say a go and see what comes up thanks heaps for the advice

Sell it and buy a Honda.
They're usually pretty reliable...



Oh.
