240z72 Posted April 13, 2012 Share Posted April 13, 2012 Ok where to start...I have a 73 240z project that im working on...it had a auto. Trans in it before. I installed a rebuilt 2.4 and a 4turbo speed trans. It ran fine before I did this. All electrical worked..started wiring it up yesterday. Last thigh to do is hook up the coil in the bay. I went to see if I could crank it over and nothing just the relay clicking under dash. Found the neutral safety switch bypassed that..then had smoke commingle from under the dash..for the 5motor wires going to my ignition switch tore up and shorting out. Replace them exactly how they came off. Hooked back up and boom..car cranked over...called it a day disconnected the battery and went inside...today I went out and hooked that battery up and went to crank it and nothing...no power at the starter solenoid. Check over everything..can't find anything..now my hazards don't work..and my heater fan will only turn on when the key is held in the start position..along with the hand brake light on the speedo..the green and white wire on the back of the ignition switch is getting really hot. Traced it out in the book and it gose to the tach. It was working fine yesterday now its acting up..also if you position the key inbetween the off and acc. Position the hand brake lamp comes on. This is very frustrating because it was fine yesterday..now its acting up really bad to the point I just want to quit and sell it for next to nothing and loose all my time and money I've put into it..so if somebody could help me out on this id be much in debt.

Leon Posted April 13, 2012 Share Posted April 13, 2012 I would test the ignition switch per the FSM. Also, you'll get more and better help if you attempt using good punctuation. Poorly punctuated, long paragraphs don't get much attention. Take your time, phrase the thoughts in your head carefully and it will be easier to help you.
