Re: [MV] M35 charging problem

Bill,
To check your alternator output, read the voltage across the batteries
with the engine running. The voltage should be at least 28V, more like
28.4 to 28.6. Each so called, 12V battery should read about half of the
total charge voltage, or 14V plus. I.E. the voltage on my car battery
with the engine running is 14.2V.
I do work in the general aviation business and they have pretty much
changed over to 14V or 28V, but the automotive market is still stuck at
12V and 24V.
Educational opportunity follows..... When you read the voltage of a
disconnected battery you are reading a no load or, "surface charge".
To get an accurate reading battery voltage should be read under load,
this can be done at a shop that is equipped with the proper test
equipment, and a KNOWLEDGEABLE, hard to find these days, technician.
BTW, you're not a moron, you are ignorant.
