I had thought that my alternator was fixed last fall but no it isn't working again.
What is going on?
Tested alternator at NAPA. Tested ok with DC output at 14.6 volts. That is a good thing!!
Batt voltage at 12.57
Wire to #1 post on alternator at 12.1 volts (Ignition on)
Wire to #2 post on alternator at 12.40 Ignition off 12.35 ignition on
Started engine and took reading at isolator center post and got 2.0 volts.
Disconnected lead to output post on alternator. Installed test lead on output stud of alternator, ran engine, and measured 40.0 volts. Revved up the engine and overloaded meter setting of 60 volts.
Isolator diodes checked out good.
Anyone have any ideas?
The alternator output is there I just can't get it where it is needed.
