Working on a friends 58 Edsel while he is laid up. I have no history with the car so don't know what the bench mark is. Won't start and sounded like dead battery as the solinoid would click when the key is turned, but nothing else. Fully charge new batter and new solinoid installed, same thing. Turn key and rapid buzzing or clicking from the solinoid. So my first thought is short in starter. But, with key off and lights on, when I honk the horn, the lights go out and the horn sounds barely activated. So, some sort of massive drain on the battery. It's still fully charged and jumping form another vhicle changes nothing. If it's a starter issue, why the drain on the lights and horn with the key off?
Does all the power go through the starter?
both battery cables look new and connections are good, tight and clean at both ground crossmember, fender bolt and solinoid on the fender.
Where should I look? Thanks in advance.
