What the heck?
I start it, drops to about 11v, fires right up. Skyrockets to almost 16v and holds steady at idle about 15.5v.
I talked to the auto parts store, we pulled out a new alternator and they are externally regulated. Am I right to say they are regulated in the computer?
Its also been 10 degrees and lower for a week or so here. And my computer (ECM) was just replaced in 2009. Its not the capacitors that regulate the fuel pump and freeze up, that is working perfect. Fuel pump comes right on.
Anyone have ideas? Should I replace the old alternator anyways? Maybe install an external voltage regulator and by-pass the computer? It scares me a little running this way. I don't want to damage my cells in the battery and I heard from the parts store it will start popping lights in the dash first. Basically, all the small light bulbs get cooked first...
