I have a 235 engine in a basically stock 1951 Chevy truck that in the last few years used to occasionally hesitate before turning over. It now does not respond at all unless a second new battery is attached to the truck battery.
I just finished swapping the 235 cam for a stock 261 cam but the electrical system was not involved in that process.
With the second battery attached to the truck battery, as I step on the starter it hesitates, turns over slowly to start, and then performs normally starting the truck. The truck electrical system is setup as follows.
Original 6-volt generator changed over to 12 volts. New 12 volt voltage regulator installed with newly upgraded 12 volt generator
New 12 volt battery (voltage verified at 12.86 volts)
Battery ground attached to bell housing adjacent to starter
Battery positive side attached to starter solenoid with new battery cable
Starter solenoid post connected to switch side of coil
Vehicle frame grounded to lower starter bolt
The bad news is that I do not understand electricity very well. I use the vehicle electrical diagram, replacing only one wire at a time, when I install something but don't understand the logic needed to troubleshoot something when there is a problem.
I need help to fix the problem, any suggestions to fix it is appreciated.
Thanks,
Ted
