Hello

I just bought this bike and previous owner warned me about this bike boiling batteries.

Is there any testing that can be made to voltage regulator? I have the mechanical one with points and some kind of coil under the metal cover.

One cell in my battery is in short circuit. I used car battery to start my motorcycle and looked how much voltage my stator was giving to battery. Voltage was from 18 volts to 45 volts and all my light bulbs shut down :lol: :clap: .

How mechanical regulator works? I had my bad battery connected when I was checking my voltage. If my battery is in short circuit, how would that affect how my regulator regulates voltage?

The GT550 alternator is like a car alternator from back then.
It has a field coil (the rotor) that is powered by the voltage regulator. The voltage regulator controls the voltage by regulating how much current goes to the field coil.

The stator produces AC current, which is then converted to DC by the rectifier.
AC voltages of 18 to 45V is normal for the stator when its not connected to the rectifier.

You probably should also check the rectifier to make sure that its OK.
The voltage regulator is adjustable, but you first need to have a good battery & voltage regulator.

The shop manual provides some useful info: http://www.oldjapanesebikes.com/mraxl_GT_Resource/manuals_page/index.php
