Need help with 36v to 48v conversion

I don't remember the wire colors, but that looks totally plausible to me.

Okay. Thanks for replying. Pretty sure I’m gonna have to haul it down to the local golf cart shop at this point.

There is no way on Gods green earth that switch is right. The 2 directional selections splice so there can only be one direction to select, the same one in both F and R ?

Are you sure you drew it correctly?

Which wire has the (+) power coming in on it?

[MilitantCack]

Yeah he’s got the power spliced to both center posts and feeding back down the orange-red stripe wire that goes to the run-tow switch. Then he has one forward post and one reverse post wired together and going down the yellow wire.

Looks crazy to me. But I don't do them that way.
Why would you have 2 switch legs and wire them together? That makes no sense. These switch legs are suppose to activate 2 different contactors.?

[cgtech]

It seems that the yellow wire has to be on in both F and R positions to power the key switch (which provides B+ to solenoid). And orange calls reverse (only on in R position). Still looks plausible to me.

I’m gonna try it a couple different ways and see if I can get it to work right. If I can’t im going to take it to a shop just down the road from me. How would you wire it Scotty?

[scottyb]

The 2 switch wires from the F and R positions (not center) cannot join. I would cut one where I could splice it back if needed just to see if the cart moves in one direction.
Those 2 wires are supposed to active reverse or forward. With them joined it seems it would be activating both F&R = a conflict. BUT we cannot really see where everything is going but I am familiar with that switch.

Has this cart run wired like this?

Where are you located ???

[MilitantCack]

This is the wiring that I started with that would barely move the tire and would stutter at half throttle. Then the controller would trip and blink green-red. The drawing that I posted is, believe it or not how he wired it.
