325 wont turn off.

My brother has a 1987 325 that will not turn off. I am ase certified so I like most thought ignition switch. But its not. I wired in a push button kill switch cutting the red power wire to the ignition. The green wire still had a 12v feedback. There is either a bad relay or something. The green wire at the key shows 12 volts even when the red 12v source to the key is cut. I wont be able to work on it for a couple days so I thought id ask if anyone had had the same pronlem before I get there. Thanks ahead of time.

I didn't really spend as much time as I should have writing down exactly what the symptoms are. I really thought eliminating the source to the ignition would fix it. If I remember correctly the dash lights (check engine etc) came up dim when you turn the ignition off but the car stays running. I believe the radio is run off a different source then original so I was disregarding it. It really seems to me like an ignition relay sticking.

I would imagine that would definitely shut it down. Im not sure why once it stalls the ignition stays off..

Re: 325 wont turn off.

I've got similar issue but in my car the coil keeps burning up literaly. I kmow that the red wire to the ignition key is always hot and the green wire goes to the coil. When the ignition is on the strart position it powers the coil. That same green wire is also attached to several other green wires. I'm going to see what happens once I disconnect them. Maybe the other parts that connect to these green wires are fried or not working properly, thus burning the coil. Does it make sense?
Let me know what our outcome is.

If your not experienced with electronics and dont need the car immediately wait a couple days. I have access to wiring diagrams etc and most likely will be able to troubleshoot it without much trouble. I just dont have access to the car all the time. If u have the manual. Start the car. Turn the key off and one at a time pull relays that could control it. Ex. Ignition relays or similar.

Re: 325 wont turn off.

That would be so cool. Yeah I'm not in a rush ill be more than happy to wait. By the way, where's the ignition relay located? I didn't know it had one. I have a 325ic 1989....thanks so much....
