New FNR switch - Problems
Hello, I'm a newbie so be patient with me if you can. LOL. I bought a new FNR heavy duty switch for an Ezgo Electric 36 volt cart. This is the second time I've had to replace the switch, thus the reason for buying the heavy duty one this time. I labeled all the wires, and I even labeled the back of the old switch corresponding to the wires I removed when I removed the old switch. I installed the new switch and now when I put the knob in forward the cart only creeps_ but in reverse! When I put the cart in reverse it goes full speed reverse! I printed a copy of what I thought was the correct wiring diagram I found from one of the threads on this site and compared it to the wiring on my cart. There are discrepancies between the two. Therefore, I'm not sure what's going on now.
I don't know the year of my cart, because it's used. I probably could find the serial number and/or the model number in case anyone that could help me would need that information. I do know it's a TXT Shuttle 2+2. I also know it is a series wired cart. It has a controller on it and a solenoid right behind it, both on the passenger side under the seat. Please, if anyone could help me figure this out I would greatly appreciate it!! |

Re: New FNR switch - Problems
The motor has a manufacture date of 9/20/99. Appears to be the original.

Re: New FNR switch - Problems
Check your rod linkage between the shifter and the switch. Rod should be on top and when the shifter is in Forward and pointing to the driver's side the shifter arm should also.

Here's a couple of photos of the rod linkage with the switch handle in forward position.

Re: New FNR switch - Problems
That's an orange control wire. It's been disconnected since I've had the cart.
I talked with a local golf cart mechanic at a nearby shop this afternoon and he told me I had to reconfigure the shift linkage. I tried that and it still does the same thing - goes in reverse but not forward. There's only two ways to fit the linkage on a square shaft, either at the shifter handle end or at the FnR switch shaft end. Either way, the cam in the switch can only go in 2 positions, no matter how you put the shifter linkage on it. So I'm confused at how that could cause this. |

Re: New FNR switch - Problems
Don't talk to that guy anymore, LOL. Is it possible that the cam is not located correctly on the board. Check the board for 2 travel limit blocks on the side the cam is on, and make sure the metal "L-bracket" on the cam is located in between the blocks, that limits cam travel to 90° & keeps the cam located Correctly.

Re: New FNR switch - Problems
well I just went out and looked at my.....its not the same.....on yours, both levers on each of the rod are pointed UP. on mine, the one attached to the handle is pointed down. certainly makes a difference.

The switch came from the factory as a complete unit - mounting bracket, cam and board, micro switches, nuts and washers. I haven't changed anything on the workings of the switch and the stops are in the right place. It can't work but one way. Thanks for your help! |

Re: New FNR switch - Problems
I know You said there were labels and your were careful, but, if You accidentally put the cables in the wrong posts, You would have exactly the problem you are experiencing.
Take a picture of the FNR showing the posts and follow where the cables go. There are many "equivalent" ways to wire the FNR, but You can also wire it wrong and typically remove the Stator coil from the circuit which would cause a total lack of torque and use very high current. |
