New to the forum.

Sort of inherited a 67 (wifes mothers boyfriend, etc.). Mostly stock - uncut. A little rust.

He was in the process of switching to a 302 when he quit on it about 20 years ago. Was also putting in a floor shifter (going to go back to the column shifter).

Worked thru the engine, put on new gas tank and rebuilt carb. Got it started, adjusted timing and ran OK. Stopped and no electric. Battery OK. Checked solenoid and replaced. Can jump the solenoid and turn it over. Checked the wiring diagrams but I am no electrical genius.

Thinking it might be the ignition switch? Are there easy (or not too difficult) ways to diagnose?

Thanks for any help.

Think you are on the right track with an ignition switch problem. When you turn the key to "start" position, you should get 12 volts on one of the starter solenoid terminals - if you don't - then you've got a switch or wiring problem. You've probably got to pull the switch from the dash - make sure you are getting power "to" the switch from the fuse box... I've seen rusty fuse box terminals cause issues - clean them - or just hotwire power to the switch with a jumper lead.

grounds 'go out' on older rigs (rust). Here the important ones might B motor to frame, the battery (not an 'ele guy', actual ele dummy) but there may B 1 on the starter...Gotta start at the battery and wrk ur way toward (continuity) ign parts, go thru all them...

I agree with chrlsful...lots of electrical issues come from poor grounds. There has to be a proper ground from the battery to the frame and frame to engine, body to frame and engine to body. All free from grease and corrosion.
Good luck
