Battery, charging condition

Postby twotone » Thu Jan 12, 2017 8:50 am

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

The voltage readings are acceptable. Good to go.
I have an excuse. CRS.

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

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

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.

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!

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!
