Cat alternator not charging

[w3ww]

Harold,

Before you do anything, check the voltage output at the alternator. Check it at
idle and also check at 1500 or higher RPM. Those older Motorola (I think that
may be the one you have) alternators seem to drop to about 10-11+/- volts at
idle and generate 13.8+/- at higher RPMs.

FWIW ....I thought I had a problem with mine and went to the trouble of taking
the alternator off, carting it to a NAPA test facility only to have them tell me
it was performing normally and it looked fine.
