Here's the electrical
problem du jour: no output indicated on my Balmar
6 Series alternator
What I've done:
Per the troubleshoot guide in the Balmar
manual, I have checked voltages at the Ford-type (4 wire) strip connector at the MC-612 regulator
. All pins read voltages within the expected ranges in all three states: 1) ignition off, 2) ignition on, 3)engine running.
I have checked the alternator
for the shaft/magnetic condition: ignition off, no magnetism at shaft ; ignition on, magnetism at shaft.
I have checked for continuity on all wiring
to and from the alternator, no problems.
I have checked the fuse, no problem.
I have checked for corrosion
on all terminals, no apparent problem.
On the possibility that my instrument panel voltmeter is defective, I am taking output readings from the feed to that meter via my Fluke 73 volt/ohm meter. It reads battery
voltage when ignition is on. Upon cranking and running five minutes, no change or increase in voltage.
In testing the AC to drive the tachometer I get about 8.25 volts, with minimal variation with engine
speed. What should it be? Would that be indicative of alternator gremlins?
I have not removed the alternator for testing at an alternator shop. That is no small task, and that is something I want to do only and if no other procedure will isolate the problem.
But I'm out of ideas.
