Brain fart regulator question Options

[mb911]

So was noticing I have less voltage while the car is running. I am use to seeing 13/14 volts as the pretty much normal. I have a fairly new marchel alternator and this year I am seeing 13v on the high side. Now I do have more electrical items, wide band o2, mega squirt, and active exhaust. Regulator going bad? Pictured in upper left. Hmm maybe I have them on the wrong pins? Might have messed that up?

Ben,

I would suggest running a "full field test" on your alternator. Disconnect the regulator, and start the car. With a DVOM connected to the battery posts, apply positive voltage to the DF wire that attaches to the voltage regulator using a wire from it to the positive battery post. You should hear a whine as the alternator goes to maximum charge, and you should see 15 Volts or more on the DVOM.

If you don't, you have a bad alternator. If you do, it is a problem with the regulator.
