Took the 63 out today for a while. Car started up with no problem. Drove about 20 miles and stopped to chat with friends.. when back to start it up and nothing. Gauges and radio worked fine but nothing when I tried to start it. Friend had older jumper cables but could not get it to do anything. We pushed it and dropped clutch and it fired up. Drove back home and and it started but battery did not act like it was charged..just barely turned it over before it fired up. I am charging battery now. Could I have an alternator problem or voltage regulator bad?? Not too good on electrical troubleshooting but is there any simple tests I could do to determine what is going on? Thanks for any advice
I would start with a volt meter. Once the battery is charged, before starting, check the voltage of the battery. It should be 12.25 to 12.75 volts. If the voltage registers below 12 volts, replace the battery. Once it starts, the voltage should go up to 13 plus volts to 14.5 volts. If not, either your alternator or voltage regulator could be at fault. Lastly, have you checked the red wire connection on the firewall side just below the master cylinder? Do a search on the forum for the red wire problem. Jerry
When firewall connector problem would gauges and radio still work.. I noticed that the amp gauge would go instantly to full discharge when I had ignition in the start position.

Thanks for the help guys. Tomorrow I will test the solenoid connection and the battery cable voltage. If those check out looks like a new starter is the route to go.
Had a similar problem on my Avanti ll that had a 350 Corvette engine. The starter got heat soaked and it wouldn't do anything until it cooled down.
They make a thermal blanket to cover the starter that solves this problem.
Or the hot wire to the starter solenoid. Or the connection at the ignition switch. Or the positive battery cable. Or the grounds.....etc.
Those things won't make the batt gauge full negative when you turn the key to start. only too much current going to the starter with the starter not moving will cause that
Update; Checked positive to starter..getting 13v. Bulk connectors all look new with no arciing marks. Alternator putting out 14.3 v. I even removed ground cable on battery with motor running and it never died. Thats telling me the problem is either solenoid or starter. Sounds like new starter w/solenoid may be in order. although it has started right up on several tries today (another indicator starter going bad). Thanks guys for all your input.This forum is great.
