I have looked at this one a bunch of times. I still can't trace that wire.
What is the best way to test thw motor?

Where does the loose cable connect to on the other end?

There is a speed controller (I am calling it that-I'm not sure if that is the name) it has 5 brass circles that look like the size of penies and the arm moves when you step on the gas pedal. It is connected to the second one from the bottom. There are a total of 5 connections that are on this. The woiring diagram only shows 4. That is where I am getting confused. I tried to take a picture but it did not come out very good. I hope the description helps.
Thanks again

Check for a missing cable on the resistor coils.

Here is what I found. A new accelorator has 2 wires that go to the opposite to the battery side of the solenoid. I am guessing that is where this wire goes. Next problem. This is connected to the 2nd post from the bottom on the accelorator and so is another wire that goes to the resistor coil.The bottom post is empty? Does this sound correct?
On the forwards and reverse selector it seems that the micro switch is bad. When I jump it and hit the gas the battery that only had 2 volts in the beginning sounds like it is bubbling. Possible bad battery that caused all of these problems. (some were caused by guessing). I'm not sure if I am getting closer. Any ideas would help.

I'm not understanding what you are describing. The resistor coil system is pretty straight forward as far as wiring. Use a diagram that you can see clearly then trace, confirm, and replace any wiring that does not match the diagram. That cart is probably 25+ years old and any original wiring should be changed anyway.
The cart will run if you wire it just like the diagrams on this site. I can send you other wiring diagrams if you can't make out the ones available here.

I think that I have it wired correctly now. I found a diagram of the speed controller with a solenoind on it. So as of now I think it is wired right. The unidentified wire hooks to the solenoind and then to the 2nd post on the speed controller. I did find that the microswitch on forward and reverse selector is bad. I am going to look for a replacement today. If I jump this switch it will kick the solenoid but that is about it. Right now I am charging the battery and will look further when they are done.
What would my next troubleshooting step be as far as why it does not run.
Thanks

Luckily you have one of the most simple carts made Once you are certain the battery pack is holding 36+ volts and the wiring matches the diagram that pggroves keeps referring you to, only a dirty connection or a bad solenoid stand between you and the fairway

Finally I got it running. The only way that I did this was by removing one of the batteries from the loop. It was the one that had 2 volts in the beginning. Can a battery go bad like this and cause the cart to stop working? Or do I still have more problems? I cleaned all of the terminals with a dremmel and a wire wheel so they are clean. I would hate to makw a $125.00 guess and find out that it wasn't the battery.

Congratulations. Sort of.....

OK, let's back up a bit. You have a mixed set of batteries. To me that indicates that at least one was replaced. The Trojans have a date stamp on the negative terminal that indicates month and year of mfr. The positive terminal is also stamped with a letter and two numbers that indicate the date the electrolyte was added and it left the factory. Check these for age. Also check the SG on each cell of each battery. Voltage isn't the only check and checking the SG is actually more revealing.
Yes, one bad battery can create all sorts of havoc.
Did you find the mfr plate with a serial number and mfr number? We still don't know the exact vintage of this cart, but again, resistor systems are pretty straight forward.

The reason I keep referring you to a diagram is to check the wiring but more importantly to learn it. Having a sparky involves learning the system. Especially with a resistor coil system that comes with it's own special considerations. Bad things can happen with that particular system. There is a lot of DC voltage dissipated by means of coils and heat at anything other than STOP and WIDE OPEN THROTTLE.

I'm not being glib or coy, I just think you need to study and learn the system. I'll help you along this path as will many others on this forum. IMO it's what this forum does and does pretty well.
