1943 AC B

Ed Petersen · Jul 22, 2010

I now own the 1943 AC B my grandfather purchased new, I know it is a 6 volt system but is it positive ground or negative ground. And would anyone have a battery number?

My fathers B was positive ground, do you have a battery in yours?

Just curious about the question...

As delivered from the factoty it was 6 Volt positive ground.

When new it was + ground and as for the battery size measure the battery box and then take the tape measure and the numbers you have with you and just measure the battery so you know if it will git or not. So simple even a 10 year old could do it LOL

When my grandfather passed away,years ago the AC sat in a barn at my brothers for years. He took out the battery and there wern't any marking to identify battery or connections. Before I start a restoration I wanted to see if she'll start. I plan to do oil, filter, fresh fuel etc... before I crank her over,but the battery info and grounding was a concern.

Positive ground. It takes a group 1 6volt battery. But watch out for height of the battery, some are taller than others.

for a test you can install a 12 volt battery out of your car or truck. Does the B have a magnito or distributor ? you may not have to do anything but put in a 12 v battery for test. biggest thing is to have clean cables and terminals.

be sure to remove the spark plug and squirt some engine oil into each cylinder and then turn it over to build up oil pressure. You may have to remove the oil line from the bottom of the filter housing to the tee at the rear of the engine and reinstall it at the tee facing up toward the head and then pump some oil into the tube to prime the oil pump. after several squirts, reinstall the tube to the filter housing. Then spin the engine to build up the oil pressure. Bob

The B is a distributor type, the 12 v battery idea sounds good though, may try it this week end

Thanks, great suggestion, I have no idea if the pressure guage works and relying on it could be a mistake. I have turned it over with the hand crank and have pulled the plugs and lubed the cylinders, but the oil at that T fitting sound great.
