6v battery charging time

Howdy-

After our recent "trying to get the 8N to start" ordeal", I am afraid all the cranking, and cranking, and cranking, drained the battery.

Now, assuming that the VR is working correctly, (BTW, how can I double check that it is?) if I jump start the old girl, and let the generator, do it's thing, how long can I expect to leave her running to get the battery charge back to where it should be?

Many thanks my brothers (and sisters)!

Joe

Bonjour Joe,
I think your battery is a 80 A/h, as battery for 2 N.
You must charge at 80 devide by ten during 12 to 14 hours, if the battery is compltly flat.
That means 8 amp during 12 hours.
Your battery is really full when you see water "boiling" in it.
Regards
Daniel

Most batteries are rated in ampere hours.. If you have a 50ah battery and it is fully drained, you would have to charge at 10 amperes for 5 hours if there were no inefficiencys like power loss due to heat etc. This is where a volt meter comes in handy. Most 6 volt regulators are set around 7.1 volts. When the battery achieves this potential, you could assume that the battery is fully charged.
Happy Motoring

Joe..... ...Most 10 amp AC chargers take about 2 hrs to charge a really dead battery. Your N-Tractor's generator is nominally 10 amps output. Normally, it takes about 5 mins to recharge the energy drained during a normal start.

Eaziest way to check your Voltage Regulator is by watching your ampmeter on the dash. 2nd eaziest way is to replace your VR with a new one.

Used to be that you could take a VR into a autoelectric shop and have it checked on a "test bench" but now-a-days its just cheeper to replace rather that check and adjust. Which is a sad commentary on "value".

Hope this helps..... ...Dell

Thanks Dell!

When I had the generator rebuilt, I had them crack open the VR as well. They said everything was "clean" and that it "should" work okay.

When I hit the starter button, I get a little more than a "click". It sounds like the solinoid (sp)is doing something, but that there is just not enough juice to turn the starter. She jump starts fine though.

I figure I'll jump start her, and go for a ride. Kill two birds with one stone: charge the battery, and enjoy a summer evening's ride on the N! :)

Thanks!

Joe

Make sure to use 1 or 2 gauge cables with clean, tight connections. Also get a little battery tester so you can check the specific gravity of the water in the battery. I'd take it to a shop and have it tested for dead cells if it fails to hold a charge.
