I just got the Sullivan 12/24 volt Super HI-Torque starter and i rigged it up to run off two 12 volt Sealed Lead Calcium batterys. But the info says to run nicad or car batterys for this set up is it ok the way i have it? What wire is the hot the smooth one or the ones with the ridges down it? Thanks for any info.

Thanks

I seem to remember me commenting in one of your threads when you were asking about soldering two 12v batteries together in series.

I told you then it was a dumb idea. I hope you realize that now. Good luck with your charging dilemma.

That was in THIS THREAD

Ok then.. How about a 24v battery charger? or is that too obvious?
Since you soldered them together you don't have a lot of options left, do you?
I might be crazy but i ain't dumb
maybe you're not crazy... er, I mean...

I did not soldier them together i got two new batterys with big wire and i crimped on ends to slid on the battery. I guess i can unplug them and charge one at a time. The biggest thing is you did not have to try and make me look like some kind of dumb AZZ.Thanks for the help from the real help.

Thanks

When you bought the starter, there were Alligator clips on the wires. The red one is the positive but if you have cut them off, make a temporary connection to one 12v battery and make sure the starter rotates the correct direction.

If you have a contact where the two batteries are soldered together You can charge each one independently without disconnecting them. Most chargers have a 12v lead acid setting.

My starter came with the battery clips in the box but they where not hooked to the wires they where just laying in the box. Thats why i don't know the true hot from ground.

Thanks for your input

Hot and ground is meaningless here. Like Peter said, just connect them so the motor rotates in the desired direction.

The rippled one is Hot or positive.
The smooth one is ground or negative.
That will have your engine turn over in the correct direction for starting i.e anticlockwise when facing the engine.

Can you just charge each battery individualy with a 12 volt charge.... or is there something i'm missing about the info?

If you have the batteries wired in series for 24Vdc, you can charge them together we a 24Vdc charger by hooking your negative from the charger the negative of one of the batteries and the positive of the charger to the positive of the "OTHER" battery.

Alternatively

Just decouple the batteries and charge them with a 12Vdc charger individually.
One at a time, then ones charged hook them back up again.

I have a simple question about charging 24volts. If i charge the 24v with a 12v charger would it just not take twice as long or would it only be more like a trikle charge and never fully charge? Please just a simple answer?

Thanks

Plain and simple, no it would not charge the 24V battery.

Damn that ground is hard! When's the right time to get out of this money sucking hobby?

Here's another option that works for me with similar equipment as you. I find 24 to be too much on 50's unless they are flooded.

If you can't learn to do it well, learn to enjoy doing it badly.

That switch setup is a nice simple idea,

but,

I just use 19V for everything. Two 8 cell NiCd packs.

Thats a nice set-up. Nice like mine. How much does it weigh, less than 2 12v batteries? Must be nice for portability.
