View Full Version : Proper voltage and poor warm start ups???

I'm not sure if these two problems go hand in hand, or are two seperate things, but here it goes...

First, I installed some new guages in my '69/327 4 speed. One was a volt meter.

When all done, the volts read around 15-16 with the ignition on. When the cars runs, it stays up around the same numbers?? I'm not a trained mechanic, but should it not be around 12-14 volts??

Secondly, the car cranks and starts fine when cold, but after running for awhile and then shutting it off, (ie gas station) unless I let it cool down, the motor has a helluva time starting again!??!
It eventually starts, but it seems like there's no crank or the battery is dying, this is VERY EMBARRASSING!!

Where should I be looking to end this or these problems??
I installed a remote solenoid last summer, to eliminate the heat problem associated with the solenoid. My headers were cooking the thing, and it would NEVER start when it was warm!
Now it starts, but I know there's something wrong!??!

Any help will be greatly appreciated!!

Thanks!
John

Depending on the alternator, 14.7 volts is not uncommon with the engine running. As for the hot hard starts, too much initial advance can cause this. Too much heat in the carb can cause vapor lock. The engine actually heats up the first few minutes after you shut it off. Poor connections, especially at the starter, as well as the windings in the starter getting hot. You can try a heat shield on the starter or do what I did, buy a mini starter.

I would think that your altenator is over charging, May have boiled the battery dry, Check the fluid level in the battery, If below the plates refill with distilled water and replace the voltage regulator.
A 69 car should run 14.5 -14.8 volts at high idle and up, at low idle it will run about 13.8 - 14 volts. Any thing more than 14.8 is hard on the battery. Double check the voltage with a multi meter at the battery.
