Default ‘68 has no acc Setting on Ignition

Hey guys

My ‘68 has been sitting at my parents house for about a year in their garage. We have been unable to start it for a couple weeks. I was testing the choke and found it had no voltage with the key on ACC. I went back in the car and turned the key through all the settings and I realized that nothing was turning on in any setting (interior lights on/off with door work.) The car will turn over but never starts and kills the battery.

So, did my ignition switch go bad? Is there a way to test where that failure is occurring?

For a test, just bypass the power setting on your switch. Bring a wire from the positive side of battery to the positive side of the coil. That will energize the coil and bypass the switch. Try to start the car with the key. If it starts, either the switch or the switch wiring is bad. Do not run the car for too long with this set-up as it brings 12 plus volts to the points and bypasses the resister wire. Do not leave it connected while the engine is not running. Jerry,

See what power you have at the fuse panel...you could have a bad fusible link, corroded wires behind the fuse panel...a bad switch..... YOu can remove the switch and test it but that may be a last resort. You have to take the center dash console out to get at the switch easy.
I would see where the power is and is not first before tearing anything apart. Check the power at the horn relay, it acts as a buss bar for some of the interior power

do you have a good and easy to read wiring diagram....theres some great colored and laminated ones on eaby

If I go all the way to the right the car does try to start.
