Hello Rotorheads

I've had my 79 for a year now and I'm convinced it has a gremlin. It may be going up for sale really soon. I've put way more money into it than I paid for it and it's still not quite right. Now it shuts off as soon as I let the key go. I bypassed the ballast resistors and it stays running after I let go of the key. Any ideas. Also I'm thinking about going to a direct ignition for the stronger spark and better reliability.

GySgtFrank will become famous soon enough
Welcome. Are you losing power to your coils when you let go of the switch? It sounds to me that you might have a bad ignition switch. You can try putting temporary battery power to the Black and white wire where it comes out of the switch on the ignition terminal (IG) circuit, it runs your coils and the short relay. I assume you've already checked the 20A ignition fuse. Alternately, use a multimeter to see if the switch is getting power to this wire. If not, it's probably the switch since you have power when starting. If so, it's downstream of the switch. Bad connection? Bad ground? They're always a lot of fun to chase down. I got the factory wiring diagram download from SgtFox on the other forum. His personal site is at RX7.Foxed.Ca. It sure helped me chase down my gremlins.
