I've got a 90 RC, when you turn the key nothing happens. It all started when I was changing the fuse on the cigarette liter, it was inop and I found a blown fuse and a disconnected grd wire. I connected the grd wire and changed the fuse, still inop, oh well. I get in it to go to work that night and it won't start. Start sw, start relay are all good. All fuses are good, just no power to the start circuit. I have power to the lights, horn, dome lights. I can start it by jumping power from the lights to the start circuit. When I remove power the truck quits running. I can use some good electrical advice. Any help would be appreciated.
Thanks, Joe

Other than undoing the wire you said you hooked up.
Check the power wire to the ignition switch, under the hood at the joint where it leaves the battery cable, where it comes through the firewall, and any other stops it makes along the way. The connection(s) may be corroded.

No offense, how long have you had the truck? Have you looked for a kill switch?

When I install my kill switchs, I cut into the ignition so everythin else works but the truck won't start. Just a thought.

I'd unhook the wire that you hooked up and see what happens.

I agree, it could be that the lighter circuit is draining your battery. Try undoing what you what you already dude
and charge the battery and see what happens.

I found the problem, it was a fuse able link right under the start relay. It was hanging on by a strand of wire. I reattached it now everything works fine. Thanks for the help. It was just coincidence with the lighter that threw me for a loop.
