Took My 69 RR 383 for a ride this morning and saw the alternator charging pegged to the max and then a little smoke under the dash! This is a brand new harness, what the hell is going on! Yesterday when I ran it, it wasn't doing this, the only thing I did was ground the wiper switch to the steering column and it was fine! any one know what is going on? Shouldn't fuses be going off?
