Hi guys,
I have installed a TrailTech onto my 1985 K100RT. It seems that I do not have a proper charge from the alternator when the bike is running now. I'm getting 12.7V with ignition off and 12.3V with the engine at a high idle (around 2000rpm).
I have only had the bike for a few months so I'm not 100% that it wasn't like this before I swapped the instruments over.
I have swapped the voltage regulator and brushes with a different unit with no improvement and I have put a different battery in with no improvement.
So, do I need the charge light connected for the alternator to work properly?
I have the alternator out and apart at the moment and have cleaned the slip rings, measured the winding resistances which all seem pretty close to what my Haynes manual recommends. Does anyone know how to check the diodes?
Thanks,
