Is it reading 13 V during the light-on period? If so then you have a crossed
wire somewhere since the indicator light grounds through the alternator only
when the alternator is not putting a positive charge to the terminal the
indicator light wire (18GA blue) is attached to. If not it may be worth
replacing the regulator for testing purposes. In the shop we don't do this
anymore - we just change out the alternator. Experience, the great mother of
all teachers, says that the parts are similarly aged and are likely to fail
within too short a time span of each other to be satisfying for our
customers: "But I though you just fixed that!", is a refrain that ages
rapidly.

Subject: idiot lights

The battery and oxy warning lights lit up yesterday morning on my 83. The
lights stayed on for a while, then flickered, then went off for a while.
This repeated several times.  The battery is reading 13 volts. Does anyone
have a suggestion?  Could it be the regulator?

Thanks,

Duane
