Hi, I have a '69 Coronet with a '78 440 that I'm having some wiring issues with. Wiring is not my strong point but I don't wanna have to take it to a shop just yet. The engine already had an electronic distributor and was spliced into the car factory points style ignition wiring, and not very well. The problem is that the alternator will not charge the battery. Both have been tested and both are good, but the juice from the alternator is not getting back to the battery, so I'm running on just the battery. The wiring harness under the hood is a mess, with wires spliced into each other and some not goin anywhere. Does anyone have or know where I can get a diagram or point me in the right direction to get this thing right. Thanks.
