I have a 76,I have owned it since 1977.
The starts every time when cold. After it warms and I turned on the electric fans, I have had this set up for over eight years. Sometimes it will not restart. If you let it sit over night it will restart the next day. I checked the current coming from the neutral switch, it had 12.5 going in and only 6.8 coming out.

Today I replaced the neutral switch and the ignition switch. it started right up I restarted it half dozen times and then it stopped.

Can someone tell me where are the circuit breakers for the starter and the ground wires are located..I only found one and it was in the fuse box .Think I have a bad breaker or ground wire.


Thanks

 

This is what I would do, I know the battery is good, but from personal experience test it anyway. Especially if it has been setting a while.

Test battery to confirm full charge, I suggest a hydrometer for this. A battery with a dead cell will cause weird issues and can be difficult to diagnose.

If you have a volt meter connect to ground directly to battery.

1. test the voltage large battery connection on the solenoid, should be around 13.5 volts if good proceed. If not correct connection problems.
2. have someone hold the key in start position and test voltage to coil wire on the solenoid. Should be continuous 13.5 volts, If good proceed. If not go to step 10.
3. Move ground connection to good connection on engine near starter.
4. Repeat test 1 and 2. If voltage is continuous around 13.5 for these test the problem is isolated to the solenoid/starter. If not you have a connection issue, check all large connections from battery + should route direct to starter. - will connect to frame and then from frame to engine.

10. connect a remote starter switch, from the large battery connection on the starter to the small solenoid connection.
11. press the remote starter switch and see if it turns over. If so the issue is upstream on the ignition circuit. (ignition switch, reverse switch, or clutch switch if equipped). These can be jumped out for testing.

Hope this helps.

Check the voltage coming out of the new neutral switch again----wiggle the connections with the voltmeter connected to see if a drop in voltage happens....(Mine had a loose wire INSIDE the connector)

Do this same wiggle-test to anything associated with thestarter wiring including the fuse box (My fusebox had a corroded IGN terminal INSIDE the fuse box halves causing a similar problem---other fuses also had badly corroded terminals.......also----clean all connectors associated with the starting system---after many years a film forms over the copper terminals in the connections causing poor connections)

 

No problems cranking this car...1967 L-78 396

no blankets, mini starter, starter shield, or any other starter band aids.....everything is basically stock except for headers......

 

The wire was lose coming out of the neutral switch. I pushed all the way in and it started. I cut it off and re started it eight times and it worked. I hope the takes care of the problem.

Thanks for the help
