I just finished discovering that my wiring harness (aftermarket) did not
match the wiring diagram in the shop manual (which I believe is the way the
car is supposed to be) and therefore that the ammeter was not hooked up
where it needs to be. To indicate properly, all power (other than the
horns, map light and cigar lighter, starter motor) needs to go through the
ammeter. Three simple tests can tell you if all is as it should be.
Turn the key on. The meter should go slightly negative. If not, the power
to the ignition switch is not going through the meter.
Next, with ignition switch off, turn on the headlights. The meter should go
very negative. If not, the power for the lights is not going thru the
meter.
Lastly, disconnect the three brown wires from the terminal at the voltage
regulator and separate the two terminal ends so they don't tough each other.
If all is wired correctly, your lights and ignition switched components
should not work. If either of them do, they are getting power from
somewhere other that where they should be.
The fix will depend on which, if any, of the above problems you have. I
have redrawn the wiring diagram in the area of the ammeter/voltage regulator
and will be glad to fax/email it to anyone interested. Just ping me
offline.
