The ignition modual (power transtor?) above the spark coil seemed to
fail a bench test. Unfortunately, I'm not confident of the way a store
clerk tested it.
I'll look at the engine management light.

I've never seen one fail. Doesn't mean yours isn't defective, though.

Also, still interested in answers to previous questions.

I didn't notice anything about the engine management light, but the
previous owner of the car said it was "trying" to come on. I think he
meant blinking occasionally.

I've now taken out the alternator. The local Advanced Auto (parts
store) can't test it, so I'm sending it out to test.
The retail price for an alternator is $146 + tax.

From the large fuse in the engine fuse box, a 90 amp was in there that
blew, 2 wires go out directly to, and only to, the large bolt
connector on the alternator. Are 2 wires normal? It seems one large
wire would do the job, but I suppose there is nothing wrong with 2.

However, I'm wondering if I replace it, maybe something else is wrong
and I might short out the new alternator. I need to test that ignition
module somewhere else too.

Thanks for helping me. I don't have anyone else who knows anything to
turn to. And I don't even have internet access (I'm in a library). The
phone is dead to, but a message can be left for me at 913 621 4046.
Leave the message for Nehmo.
