Voltage reg.......Help needed

I have my sons 52 F1 (flathead 8) up and running and everything is new starter battery and all and it is running good except, I am running a 8 volt battery in the six volt system and the voltage reg is "ticking" at a low-to-mid rpm and when it "ticks" the gauge also moves and smoths out a higher rpm. I don't really want to change it over to 12 volt until we rip it apart to rebuild it. Does it have anythig to do with the 8 volt battery? Thank you in advance Kyle

 

I would check to make sure it isn't overcharging, and if it's charging enough to keep the battery up. Check the voltage output in all ranges. Charging voltage shouldn't be more than 8 or 9 volts.

 

The problem is with the 8 volt battery, take it out and go back to the 6 volt battery. I too have a 52 F-1 that still has the 6 volt system and had a similar problem when I tried using an 8 volt battery. Just go back to the 6 volt and you shouldn't have anymore problems with it.

 

If you are running the old style of voltage reg, it's probaly just the contacts inside it popping on and off as it tries to charge and sees 8-9 volts on the system instead of 6 or 7. See if you can get the voltage regulator adjusted or recalibrated to run in an 8V sytem at your local starter/generator rebuilder.

 

Or this.....

 

Thanks guys..........Kyle

 

if you have troble with your 6 vplt bat, check all your conections, make shure that they are clean and tight, check your ground and the ground at the starter motor. also make shure that your battery cables are #2copper or bigger. good luck

my guess its reverse current cutout cycling as the 8 volts overcomes the gen output at low rpm

 

An 8 volt battery is a band aid. A properly set up and maintained 6 V system will work just like it was designed and there is no reason for going 12v unless he is contemplating modern accessories.

As mentioned above clean and tight connections with proper sized wires and cables are necessary for proper operation. Primary battery cables should be 1 gauge minimum. Also if there isn't one run a ground from the body to the frame also. Still running 6 V in my 46 Plymouth and it hasn't caused problems or been unreliable.

 

Agreed, just go back to 6V and verify all is well with wires, connections, and the obvious generator/regulator.

I would use no higher than 2 gauge wires. If you can find 1 or 0 gauge the better for you. Your car should not have too much trouble if it is a six.
