1953 Super A. Never showed charge on guage very often. Polarize and it charges for about a minute. Installed a unknown condition VR, polarized, charges at 6.90 volts at WOT, 6.50 volts at idle, battery tests at 6.35 volts engine not running. 6 volt positive ground system. Are these readings acceptable?
Thanks, Tom

Re: Battery, charging condition
The voltage readings are acceptable. Good to go.
I have an excuse. CRS.

Re: Battery, charging condition
Thanks for the reply Eugene. Both VR's are overseas made, so we'll see how long it lasts.

Re: Battery, charging condition
Anything above battery static voltage indicates it's charging. Would prefer to see readings around 7 volts but anything above static level is good.

If you can't fix it with a hammer, you've got an electrical problem.

Re: Battery, charging condition
Tom, here's a link to "How to Perform a Tractor Electrics and Voltage Drop Test" in our How To section. Should be a help.

Re: Battery, charging condition
Thanks Stanton. Good info. I should note also that my SA has always been a good starting tractor, and when I started it yesterday, it gave a slow groan and popped right off. I also noticed that the volts kept increasing slowly the longer I ran it. I ran it for about 20 minutes. I think a slow charge with a battery charger for a bit might bring the charging rate up. It was 65 degrees here in Pittsburgh yesterday, I should have done it then!

Re: Battery, charging condition
A well-tuned ignition will make these tractors pop over even if you can only get one slow-ass crank from the 6volt battery. It amazes me every time when I start my Super A in below freezing conditions and it cranks slower than It would if I used the hand crank, but as soon as that impulse coupling snaps... BOOM!
