Subject is an 89 200tq. Guage on dash displays 11-12V with the heater
on high and the headlights on. Appro 14V with all accessories off. The
(aftermarket) radio seems to have some alternator whine. I have
done the following already:
Replaced alternator and tightened belt
Clean batter cable connections and grounds at battery, starter, and
Cleaned fuse box relay connections.
Removed spade near jumper post on connector on blue stator wire
Relayed headlights (helped some)
Checked grounds on intake, valve cover, and above left side kick panel
The car does not appear to have the infamous battery cable splice. Is that
5ks only? I found no ground connection above the right side kick panel.
Another oddity is that the positive battery terminal seems to run fairly
hot even after cleaning its connection. I cannot determine where the
power feeds to the fuse box originate. Any other BTDTs would be helpful.
Another problem this car has is that the rear defroster does not work. I
replaced the switch (which was burned inside) and that made the heated
mirrors work, but stil no rear defroster.
