Re: 2010 G29 electric stopped working
OK. Your controller and your motor are looking pretty good.
Unplug your regen sensor which is located on the end of the motor. Try car. Check continuity on the three TPS wires. |

Re: 2010 G29 electric stopped working
For what it’s worth I just finished fixing a g29 yesterday with most of the same problems. It had a faulty TPS and the controller was dead. After installing the new controller and TPS I was getting readings and solenoid would click and reverse buzzer worked. But the motor wouldn’t engage. Put it on jack stands and had someone push down on the throttle. I was at the back manipulating the 26 pin harness and the motor would sometimes engage. The terminals inside the plug were not always making contact,I have come across this problem a couple of times before. The wires (orange,blak,blue) from the TPS were not giving the signal to the controller. My cheap solution to verify the problem was to take three thin straight pins and push them into the wire side of the harness plug.
The cart ran on the jack stands so I took it for a long test drive tringing to find the roughest terrain possible. Cart ran flawlessly. I determined that the terminals in the harness plug have lost their tension and won’t always make contact. The dealers don’t service the plug parts and I haven’t found info on a tool to take it apart to change those terminals. You can get a complete harness from Yamaha or you can try my trick Good luck |

I stuck my hand through the back, pushed down on the harness where it plugs into the controller, stepped on the accelerator and that darn thing started to move. Unbelievable! All this grief because of a bad contact. And I also know why: When I started to diagnose, I unplugged the harness from the controller and in order to put my probes from the Ohm meter at the contacts in the harness, I inserted some thin wires. But they were not thin enough and inadvertently I opened up these contacts; so when I plugged the harness back into the controller they didn't make contact anymore. So I did now the same thing like you: I cut little pieces of very thin wire, stuck them into the harness end, plugged it back into the controller and everything is gravy again. Well...I sure learned my lesson on that one. Thanks for pointing my in the right direction. Now my sleepless nights have found an end. |

Re: 2010 G29 electric stopped working
Here is what I got. The tester is fine, just the harness does not fit for a G29.
