I went and looked at this 91 talon turbo and the car seemed ok.
anyway,i saw a wiring harness dangling behind the battery with its plastic piece still wrapped around it.On the end near the battery was a clip to plug into something.I traced the wires(2 of them,red and black) over the part i have circled in yellow.the wiries cannot be seen but I made them yellow also.Looks like something was removed from that position and it had vac lines attached to it maybe.The other part on the left is still there.
what is it?have anything to do with possibly the alt overcharging?he said it was overcharging but I am not so sure after I saw the belt was gone and the battery was dead..lol
