Issue 1: Blows new condensers at odd times (no pattern).
Might take a day... might take a week. Car runs and performs
rather well otherwise. They just up and quit.
Some things which make a good condenser fail: High
heat, insufficient capacity, mechanical deformation,
high-voltage arc from cracked distributor cap or rotor.
Marginal insulation quality in a distributor cap may allow
arcing inside if a plug wire is disconnected.
Issue 2: Alternator light comes on 5 minutes after parking.
The alternator light does not come on while operating nor
upon turning off the ignition... only about 5 minutes later.
It does come on when the key is turned to on before
cranking, so it appears to function correctly. Now and
again it drains it's battery, but when testing has no spark
when striking a cable to terminal suggesting no grounded short.
I think that when the engine is shut down with the points
closed it is letting the battery back-feed through the
condenser somehow. Suggestions?
It sounds like a gremlin is turning the ignition back on
after 5 minutes. This would turn on the dash gauges
and activate the ignition points, thereby draining the
battery. This could mean a faulty ignition switch
or ........ ran out of bright ideas.
