Your regulator is failing on the 60amp...simple fix.So, while waiting for fuel tank parts and other goodies, starting to think about the alternator. The 60A in it overcharges....
The way I'm understanding this is:
Wire 568A is the "enable". With this wire disconnected, the alternator does not produce output. With it connected, battery voltage quickly goes above 30V.
The voltage adjustment screw makes no difference.
Wire 2A is a bit of a mystery to me. It goes to the protective control box and to a frequency switch inside, right? So that tells the box that the engine is running? So shouldn't affect alternator output (not related to my problem), right?
Should I do anything else to test this thing? I mean, it seems like the regulator on the alternator is bad.... or am I missing something?
I did buy a 200A Niehoff dual voltage alternator to play with... It may or may not need repair, but I figure it maybe more fun (ie. a better investment of time) to repair the 200A and install that rather than repairing the 60A.
