Alternator output questions
For years I have had a perfectly functioning charging system. I have the stock 10yr. old, 95A Subaru alternator, a two year old Optima red top battery and the alternator wiring mod.
Using my plug-in voltmeter, My voltage upon startup was 14.4V. Running normal accessories like A/C and lights gave me overall operating voltages of around 13.8V while driving and about 13.5V at idle. I never had any starting problems or the "Christmas Tree" syndrome. I have only done two electrical modifications recently: I added a 30A relay to power my Hella Supertone horns, which was pretty straight forward. I also replaced my alternator plug with a new one. This consisted of cutting the two wires from the old plug and soldering/shrink-wrapping and taping the wire connections to the new plug.... however Since I did this I noticed that all of my voltages are around a volt lower than they were. Startup is now at 13V instead of 14.4V. Running around now is about 12.6V with air, etc. When I cut the two wires from the old alternator plug, one of them accidentally touched the manifold and made a small spark, but blew no fuses. Could I have done something to the diode or rectifier? The car still runs and operates normally without any sort of symptoms or lights, but for the first time ever with A/C lights, stereo, etc. the voltmeter will occasionally read 11.8V at idle--This has never happened before. Is it even worth worrying about? Is there any tests that can be done to check this out? It sounds like something else is drawing current, but the horn relay is not energized normally and is totally isolated. As I said all my connections are soldered, shrink wrapped, taped and run inside spiral wrap. Any help is appreciated. .
