Batteries Fully Drained + Overcharged = Self Accelerating & Smoke

Also, make sure the high amperage cable is always the first in the stack when you’ve got multiple wires on one post.

Looking forward to seeing you get it all straightened out.

I am new to this appreciate the feedback.

Did not know that it's bad to have heat shrink inside the first couple millimeters of the connectors. I have been trying to do that, just to sort of make the wire a little better, and then a larger piece of shrink tubing that goes over the the lug to secure it better to the wire.

Are you suggesting the shrink rap inside the lug is bad or just not neccesary?
With the high power wire "first" are you're saying place it in the bottom? Place it on last?

Thanks for the info.

Hey so I've torn everything out.. redoing all of the wiring.. in doing so I found water inside of the circle thing (see picture).

So far the wiper blade "looks" fine. Cleaned off the contsvors.

"With the high power wire "first" are you're saying place it in the bottom? Place it on last?"

The "high power wire" should go on first, or the bottom. Then add the smaller wires on top as needed.

Aside from surviving few pops, a little smoke, and a siren type noise from a battery at one point.. I removed and cleaned up the wiper board, removed and cleaned up the F/N/R control box, clipped and reset all the connections. New ignition switch.

IS THERE SOME TYPE OF TESTING I CAN DO PRIOR TO FIRING THIS UP? Am learning a lot however I don't totally understand how much of this electrical stuff works. Add to that the possibility of crossing a wire, not grounding something, reversed polarity, ignition key switch wiring being backwards.. I don't know.

Any tips on not injuring myself or the batteries much appreciated.

I know I'm a moron but the diagram has a different switch and I'm not sure which is the ground etc. This seems correct yeah?

Ok so.. when I turn the key on, all good. Neutral all good. Forward or Reverse the cart tries to accelerate and I get an immediate loud spark/pop. It is coming from the passenger side, right by the F/N/R hardware as best I can tell. Each time I've had sparks and pops it is coming from this area.

So check this out.. the wiring diagram.. everything pictured in the diagram is how I've got it hooked up, with one exception.. the diagram directs me to hook up one if the little black wires coming from the F/N/R rocker box things to POS however I have picture proof that it has always been hooked to the NEG on the same battery. See attached picture. There have always been 3 to the NEG and 1 to the POS. When I touch the black wire to the POS, I get sparks.

Maybe the previous owner modified it, and I'm new but doesn't that mean there should be an additional offsetting conflict? If this one is hooked to NEG instead of POS, then somewhere else I should have a conflict with the diagram but the other way around. The whole circuit polarity reverse polarity thing.

This also explains the energy being unexpectedly applied.. I had to have screwed up the wiring when I was putting the F/N/R box back together. One if the rocker speong box things looked a little jacked up.

Thoughts? I'm trying to find a wiring diagram for the F/N/R box. Might just replace the part if it isn't that much.. what's the Rock Auto of the gold cart world??

Thanks all
