Okay so my wrench called last night. Car was all finished & he went to fire it up. Turns over fine but no start. This is what it was doing before the fire. Also off & on it has plagued me since I got the car. I've replaced the ignition with multiple times. I added a push button for the starter to take that off the switch. Seemed like there was to much power going through it which I thought was from the starter. Obviously it is not.
One thing is almost without fail as soon as I put in a new switch & use it I get smoke from it every time. It would be fine right after the brief smoke so I didnt worry to much about it. What else is feeding the ignition switch that may be pushing to much power through it? What do you guys recommend doing here? Cutting out the switch completely? Do you think the problem lies somewhere besides the switch? |

Jamie,
You need to have another electrician who has experience working on autos check out your wiring issues. From what I have read here, the ones you now have are missing some issues that need to be checked in a better way than hooking up the power and seeing if it works or smokes. Please do this before there is another fire! The first thing that needs to be done is to remove the wires for the switched loads,( the loads are what the switch sends power to) and check each one with a multi-meter to see how much current it will draw. The battery needs to be disconnected to do this. You will be reading each load wire to ground to see what the ohm reading is. The lower the ohmic value, the higher the current will be. If the loads exceed the rated capacity of the switch, then you will need to install relays or a heavier duty ignition switch ( which is probably not available). If your ignition switch wiring is stock, there is one large red wire that goes to the switch and several that are loads. Tom |
