Single-Wire Alternator Questions Again

[Sledge]

Jim:

Thank you! I thought that it should read around 15 or so volts pretty near all the time if the darn thing was working, and certainly more than 12.6 or so.

So here I go again.

I don't think the battery is the issue as it cranks the engine just fine. If it had a short between cells I would have thought that it wouldn't crank the engine. Is there a more sophisticated battery test that should be done, or other battery fault that could be contributing to this?

Also, when I started the car this morning, cold, the alternator still did not come on line. So I don't think it is a heat problem.

Time to take it to an expert I reckon.

Any other suggestions would be welcomed!

Thanks

Bill
