So I finally got around to try and start my 82 2.3l mustang today and it cranks over very slow. The car does not have a battery, I just used my tacoma to basically jump start it. As I was trying to jump start it the Voltage on my tacoma was dropping into the 10's (10 volts) and the positive/ negative wires on the mustang were getting warm! Also the negative side of the starter Solenoid was also very warm. All wired connections on mustang are good and tight! Car does have spark and fuel! Any...
