Long time lurker first time poster. I was laid up with a bad knee and the kid wanted to start the 57 for a friend, unfortunately he put the battery in backwards and now I am trying to recover. Here is what I have 57 4dr sedan, SBC 350, Mallory unilite and Hyfire IV ignition, 3 wire alternator. I am checkking all my electrical in the car before I start repairs. The fusible link on the violet wire to solenoid is totally fried (as in evaporated). Green wire from ignition switch to ballast resistor has direct short 0 ohms to ground. Red wire from ignition switch reads 26 ohms to ground. Any ideas whether 26 ohms is normal or is my ignition switch going bad? Any and all help is greatly appreciated.
