TXT wiring help for big block with pedal start.

jellyroll22

I bought a gas cart that had been 'slightly' on fire to put a big block in and I am stumped trying to put back some of the stock wiring to run the S/G. When I got it all of the wires from the pedal box were cut, which is my first question. I have black, white, green, and red coming from the pedal box. Looks like red and green hooked to the MS inside the box is correct which makes me wonder what the white and black are for??????? Also, where the heck do any of these get attached to?? I can't figure out where the pedal box switch is in the diagram.

I have all of the wiring schematics through the stickies and the first few HUNDRED pages of google but can't figure it out.

Better yet, any one have a schematic of a chopped up harness that would show only the wiring necessary for the S/G with the pedal start and charge the battery?

Help

Most of those google images are for electric carts, you can tell because they have 6 batteries. Most gas 4 cycle golf carts are similar, you have hot wire to the key and then to the pedal switch. So both must be on to run. That hot wire then goes to the main solenoid that turns on the gen to turn it over, and also goes to ignition if it requires power (or a kill switch of some kind if it does not need power, depending on what ignition the stock engine had). Then the cart is running. The solenoids are constant duty and stay on while running, the gen will turn into a charger at higher rpm but starts at low rpm. The VR may also get the hot wire so it functions when running. It connects to the gen with the small wires that run a field in there, when the VR wants to charge it sends current to the field and makes the gen charge. These wires are usually small and have nothing to do with the big cables to the battery. Then you have a ground wire to the gen and or engine, the VR, and that is about it. You may have a reverse buzzer that runs off the shifter, usually a fuse for the hot wire, etc. It may have a low oil sensor hooked into the ignition and engine block.

To put a clone in you typically need all the gen and VR wiring but nothing else, the clone has a mag ignition that needs no power you can rig a relay to kill it. The gen works just like stock, you only need tell the clone to stop running when you let off the pedal. If the cart had a mag engine it should have a kill wire to shut it down.

Thanks Sho, I appreciate it. I'm also in W MI between GR and KZOO. I'm sure I have the right schematics as i am more familiar with EZGO electrics. I stuck a clone in a Yamaha then saw this TXT so I grabbed it and thought I might as well order a full kit from Vegas carts!

The wires from the pedal box are causing me the most frustration right now, can't figure out why there would be four. Seems like a hot going to the switch and a hot returning power when the switch is active would be it. I get the four wires on the electric carts with the ITS module and that is how the degree that the pedal is pressed is measured. Doesn't seem right with a gas.

I have no low oil or reverse buzzer so that simplifies things. The stock engine is gone which is partly why I'm in the position I'm in, some of the parts came in a box with the cart.

Anyone have a VC/clone powered TXT that could help with what their wiring looks like?

Thanks for the help!

Then you have been rained on too! What is with the rain and freezing rain, I'm tired of it, rather have snow. The diagrams I see only show a micro switch, and that is what they sell for a pedal switch as well. Either way that is all you need from the pedal, is on/off. I don't know as much about ezgo have not worked on as many, but the usual gen start gas engine system is pretty standard with all of them other than what ignition they use. All you need is to cable up the gen correctly to the battery, wire the key and pedal over to the start solenoid. Get a std bosch type 5 pin relay for a car ($3 or so, double if you want the harness/plug too) and hook relay to the pedal hot and ground. Hook the other side to the kill switch and ground but you have to use the normally 'on' pins, that is why a 4 pin relay will not work. That will kill it when you pedal lift. You can unplug the relay if you need to run in emergency, or for example I can pull start mine that way. Then connect the VR as shown in stock diagram.

There are plenty of TXT guys on here someone will be around.

I will check to make sure tonight, but I am pretty sure the 4 wires coming from that box are the ones you "tuck off to the side", when you pull the Robin motor and replace it with a Vegas Carts motor. I know one of them goes 12vdc + when you push the pedal. I only needed the one wire to add a relay to kill the motor when you take your foot off the pedal, the rest are not used.

Ok, what I posted above is wrong. (I wish I hadn't killed so many brain cells years ago) I have 2 wires coming out of a 2001.5 TXT pedal box. One is green and the other is red. The red gets 12 volts from the reverse alarm and the green goes to the solenoid, by the battery, it is a different shade of green than the wire going to the S/G. The green out of the box, I think, is switched by the key. I'm not even sure if my wiring is stock. When I bought it a year aco the previous owner had added lights, turn signals, and a horn. All of the extra wiring and fuse box is above the solenoid. I added a schematic that kind of shows the wiring.

Ezgo only has one field wire, yami has two the ezgo must be connected inside. Anyway, MS3 looks like the pedal switch and only 2 wires.

Thanks guys, hoping To get it figured out this weekend.

Just hook up the power to key (with the battery ground disconnected), check wires to pedal switch, then you should see 12v hot on the right wire from the pedal when you press it down. That is the wire you want, with your tester ground on battery. Also look around for a fuse and check it, connections, etc. I don't know what you have, but the battery cables to gen are another circuit do that one, the VR circuit, break it down like that it should be easier to do that way.

Thanks again for the help sho. Got it figured out and the VC 460 is ALIVE!!!
