Hi everyone

I have a charging problem on my XV1000TR1. I changed my regulator but I still have more than 16 volts coming to the battery. I need to check my alternator. Does anyone know the voltage I should get on the 3 wires at the output of the alternator?

Thank you in advance for your help

The generator produces a few dozens or even hundreds volt. But i believe it can only fail in the way, that it produces less or zero voltage, not more... Thus probably the new regulator is also broken?

Hi thank you for your answer. the problem is that this is the third regulator I have tested. For information, it's a caferacer project, I put a m-unit blue box for the electrical part and the brown wire of the regulator is not connected. Maybe is it necessary to connect it ?  

Possibly the brown wire isnt there just for fun...

What is brown wire you speak of?  :)

Assuming its a Mosfet reg, 3 phases in (yellow?), Pos and Neg out red & black.

Brown wire is the voltage reference for the original regulator. Also called the sensing wire, it's how the stock unit determines whether the battery needs charging or not.

Ok thanks but I replaced the relays and fuses with a motogadget m-unit box.

The lights, turn signals and others are connected to this box.

Do I still have to connect this brown wire somewhere?

I still have the same problem, the regulator works fine for a few minutes and all of a sudden, it goes up to more than 16 volts at the battery.
This is the third regulator I've tried and still the same problem.

Just connect the sense (brown) wire to 12V wire behind the ignition switch, if you don´t have or want a switch (keyless)  for example connect parallel to the 12V wire that goes to the Ignition coils probably coming out of your box?
I don´t know much about the m-unit box, but there should be a switched 12V Output. It is just important not to connect direct to the Battery +, that will decharge it when the engine is off,
