98 txt runs very slow
Have a 98 txt, non pds, that is running very slow. Like 1/2 mile an hour. Initial tests. Using the Tech manual.
Pack voltage 38 First test: Key on, In forward. Pack voltage at M- + B- Pedal fully depressed voltage drops to 20V Any thoughts initially, or best place to look. I did try a few other tests in the trouble shooting section ITS, Solenoid, etc... All seem to be in spec. Bruce |

Re: 98 txt runs very slow
What is the pack voltage when the pedal is fully depressed?
What is voltage between controller's B- and B+ terminals when pedal is fully depressed. If both of those voltages stay at 38V, or at least don't drop all; the way down to 20V, then then the problem is either the throttle circuit or the controller. |

Re: 98 txt runs very slow
The pack Voltage only drops a volt or so. The B+ and B- test does about the same. When I tested between B- and ITS white wire got 17 volts. High but the voltage was there.
And thanks for the quick reply Bruce |

Re: 98 txt runs very slow
Okay, that narrows it down to throttle or controller.
Attached is how to check the throttle. |

Re: 98 txt runs very slow
I will make those tests tomorrow. Most everything is pointing to controller. It a neighbors cart so I just want to be sure (or mostly sure) before I have him pull the trigger on a controller. The troubleshooting section can be a bit overwhelming when going through it.
Thanks for the direction. Bruce |
