2012 Electric Precedent does not run
We have a 2012 Precedent that does not run. Batteries are at 50v. When scanning the controller is not reading when the car is put in forward or reverse. We verified rocker switch and is working properly with continuity testing. Also tested the wires from rocker switch to controller and we get continuity. Would this be a controller fault?

2012 Electric Precedent does not run
So you hooked up a Curtis handheld up directly to the controller couldn’t get it to power up? If that’s the case then you need to start at your key switch and work your way back. More than likely it could be the activation side of your mcor isn’t operating right or it could be the OBC has it locked out. Try disconnecting the main pos and neg cables for 5-10 min and seeing if that makes a difference; if it doesn’t then my money would be on the OBC being locked out. Hope this helps

Also the car had been sitting out for over a year without use and batteries were out. We just installed a new set of batteries to test vehicle. |

Re: 2012 Electric Precedent does not run
Did You also verify the orange wire on the center position of the FNR had 48v?

Re: 2012 Electric Precedent does not run
It's either a bad controller, two bad wires between the f&r switch and the controller, or a bad F&R switch entirely. I doubt it's a bad F&R switch, because it would have to fail in both forward AND reverse in order to give you these symptoms. This is considering you're getting power to the orange wire on the center pin, which you said was good. I would start by checking for power at the blue wire and the brown wire at the controller 16 pin connector. The blue wire is for reverse and the brown wire is for forward. If you're getting full pack voltage to both of these wires when the F&R switch is in the correct position then your controller is your issue.

Re: 2012 Electric Precedent does not run
That voltage reading could have some significance to the issue.
The power to the FNR comes from the Tow/Run switch through a fuse and a couple of sonic-welds, but it should not cause that kind of voltage drop. First verify that the 16ga pink wire on the Solenoid big post (Tow/Run power) is connected to the battery side of the Solenoid and not the Controller B+ side. if the pink wire is connected to the correct Solenoid post, does the voltage on the FNR drops when you turn the Key Switch ON and try to use the cart? |

rocker on neutral - 12 v on brown & 45 v on blue when activated to either forward or reverse - we got almost BPV on the activated side same readings at rocker switch connections. handheld was giving us correct throttle readings yesterday, then today no readings. same for F&R signal which remained off on handheld reading when activating one or the other. Now all of the sudden, we got F&R signal reading on handheld (when activated) and throttle giving us proper readings again and the car started running. would this be from the system being without use for so long? car had been stored for more than a year with bad batteries and no use. |

Take apart the switch. It’s easy and you can immediately recognize corrosion etc. if you see it.
