If I want to jump start my 6 volt positive ground Model A with another fully charged 6 volt battery do I attach the positive cable to the head bolt and the negative to the starter connection.

Next question when I want to put my charger on the the car do I put the red positive cable on the ground and the black negative on the starter ?
Thank you from a newbie !

Yes that is correct.

You could try it the other way..... Just to see what would happen... Think of it as the learning curve... OK.. don't try it.. I was only kidding. I know some of you out there might.
 
I jump mine daily with my 01 jeep wrangler positive to positive neg to ned on the bat does not hurt any thing

I still don't trust my self... I will un hook both cables from the battery and then
hook up the charger like like normal red to positive and black to negative.

Hey Jeff HotRodJeep,
Red is still positive, black is still negative, whether hooked up or not.
Live dangerously like people have been doing "Normally" when charging these cars for the past eighty years without problems.
 
Someone sent this to me and I thought it might be helpful.


….you need keep the positive with the positive and the negative with the negative to prevent the smoke from escaping from the wires. This is called polarity and is important so that when a fuse or circuit breaker fails it will blow instead of suck and stop the unnecessary loss of wire smoke. We know from experience that when all the smoke has leaked out of the wires, electricity usually no longer works. It’s all spelled out in something called the electronical theory which also states that ‘electrons in a wire with no loss of smoke tend to make things spin (like motors) while some of the other properties of electrons tend to absorb darkness (like lightbulbs)’….


Have fun.
 
ya I have a bat but no bat charger and I havent been running it long enough while im working on it to charge the bat so if it dosent sstart prity quick ill have to push it out of the grade and jump it with my jeep.
 
Make sure the LAST connection is to the engine block.

Making the last connection at a battery post can cause a spark and explode the battery.

Since 1967 I've had two batteries explode in front of me and one explode in the garage while on a 1 amp charger overnight. I also had a 4 amp charger catch fire during the night and burn up while charging my 87 Dodge Dakota about 12 years ago. Luckily the hood was open and the charger was setting on the radiator, so the fire didn't spread.

Best to not leave a battery charger unattended, or if you do make sure the charger and battery are placed where the fire can't spread or the explosion can't hurt something else. Stuff happens!

If the battery ever gets warm while being charged, turn off the charger and junk the battery. Attempting to save a junk battery can be costly.

I never charge with more than my 6 amp charger. A heavy charge can buckle the plates.

BTW, I still have the acid marks on the hood of my 91 Olds from the battery that blew up while on the 1 amp overnight charge. I was charging a junk battery of mine, which was setting a couple feet in front of my dad's 91 Olds. The biggest piece of that battery wasn't even the size of a golf ball.
 
Good tips, Tom W. I also always loosen my filler caps so the gases can escape. But I make DARN sure there are no sparks around!
 
How is it possible hooking a 12V battery to a 6V battery doesn't cause something really really bad :)
 
Hi Mr. Tube,
Depends on your definition of REALLY BAD.
If the lights are on, you can kiss the bulbs goodbye.
The starter will be operating at a much greater speed which could cause the original type Bendix to give up the ghost.
Don't have your foot on the brake to possibly pop the brake lights.
I wonder if too long an application of the 12 volt cables could take out the coil?
Otherwise....
I guess its OK, but I would rather use the crank or a push start, myself.
Fortunately, with my Optima 6V battery there always seem to be a reserve supply of good juice. :D
 
Group,

When I had my 1933 Chev., I did jump start the car (6 V neg Ground) once with a 12 v battery.

Worked O.K. but I sure was nervous.

I just touched the connection briefly, but the current flow was very large.....

Wait, Even a NEW battery will get warm while charging... While charging a battery, the caps should be taken OFF, if not, this is how the gas builds up inside & very slowly comes out the vent holes & then with the first spark, BOOM!!!..
