I recently bought is 68 Barracuda 340 formula S car. Some of you may have seen it on craigslist. The car sat in a storage facility for about six years. It’s a solid car and and I got it running after flushing all the fluids.
It seems to be only running on the battery (it cuts off if I unhook the battery while running). I’m not getting 12 V out of the field tab on the alternator, I’m getting 0 and only getting 11.4 on the larger post on the alternator. I’m getting 12.3 volts at the battery. I’ve installed two alternators after I realize the alternator which came on the car was no good. I’ve change the voltage regulator. I’ve replaced the battery, and cleaned every electrical contact and wire point between the alternator and the battery. A couple of questions:
1- could I have gotten 2 bad alternators from Autozone? I will try a third one from them and have them test it before I leave the store with it. The fact that I’m not getting 12 V out of the “field” tab indicates to me that the alternator is no good.
2-I should be getting about 14v at the battery terminals right? That would be the alt charging it.
3- I do not see a ground strap from the block to the frame. Is there supposed to be one and if so where? The negative battery cable is grounded on the block/head and was cleaned and reinstalled.
Thanks folks
Rusty
