Mystery Cable

Ignore the missing battery at the top of the picture, it is out for charging.
My question is about the 4g cable next to the solenoid just under the Trojan. It comes from under the accelerator box that the solenoid is mounted on. Any idea where it may go? This cart supposedly runs when the batteries are charged. Right now I suspect one of the batteries is bad. I am taking them out one at the time and charging and testing them. So far all the batteries seem to charge when charged solo. One started at 3v so I watered it and charged it. It is now at 6.2v. The rest of the batteries started at 5v and now are all over 6v. I assume the dry 3v battery was not allowing the rest to charge. The entire bank was at 24v when I first tested it. Advice good and bad are appreciated.

It's hard to tell form the picture. You can find a wiring diagram in the EZGO resource forum that should help you out though.

I remember hearing someplace that the EZGO charger for a 36V pack would not start the charge if the totally battery voltage is less than 28V. This was the problem on my 95 EZGO. I had two very low batteries. Charged them above 6V and the whole pack would charge fine after that.

I'll try to remember to get a picture of my 73 EZGO and post it for you tomorrow.

The connected end of the mystery cable is going to a post on the box that the accelerator linkage is hooked to under the solenoid in the picture. It is the wire that is obviously unhooked in the pic and goes around the accelerator thingy and passes under the green 18g wire. I almost have my batteries at 36v so I am getting close to seeing if I can get this thing to run. All the diagrams I find are for newer carts. I need something for 71-74 carts. If I need to post different angle pics let me know. My neighbor has a 74 and an 86 that everything is in different places and that wire is not present so that has been no help.

I found a wiring diagram for your cart, but can't figure out how to put it in this forum. If you can help me with it, it may help you with your cart.

Ok...so now the cart runs despite the mystery wire. It only made it in and out of the barn but it moves nonetheless. The problem was the wire from a microswitch on the throttle assembly to the solenoid was missing or chewed off by a rat or something. There are still a ton of mystery wires in this thing. I think some are supposed to go to a buzzer looking thing but I would rather not have that operational anyways. My next thing is to get the batteries to hold a charge. Most seem to sit between 5-6 volts but the charger was not actually charging before. I have charged individual pairs with a 12v charger for a short time and replaced a known bad battery and now it seems to be charging. The charger jumped up to 25 amps when I connected it this time.

Links are fine here except from BGW. Every time some one links a pic from BGW Scroaty changes the pic to porn so I had to block that site.

Unfortunately BGW is where the wiring diagram for a resistance cart is located. When I tried to pull the picture off the site and repost it, the picture was so dim and fuzzy that it was mostly unreadable. I just don't have the time to spend a couple hours re-drawing the diagram. I am not saying that I like the folks at BGW. I just joined several sites when I first got my first cart which was 1973 EZGO electric, because it was so hard to find any information about it since it was so old.

Hey now that looks closer to what I have than anything I have seen. I can tell you my info plate is under the seat but hardly legible. Can anyone decifer the numbers on it if I can read it?

Take your numbers from the plate, then go to the EZGO site and email the numbers to them. They will get back with you about what cart you have. This is how I found out that my cart was a 1973.

Boy are mine hard to read. They have been painted a bunch. I am going to try some paint thinner on it next.
