Re: 2002 TXT PDS 3 beeps
Ok. Ran through the troubleshooting steps in the service manual. The only unusual readings I got was:
Speed control section #13 says voltage between controller F1 and F2 should be around 2.7v. I知 getting 22v. Same section, #32 says should be reference voltage(38.8v) I知 getting 32.8v. (Pin 1 in J4 to B-). Same problem at #35, but... Tests #33, 34, 36, and 37 all test at reference voltage. Lastly, #51 (Reverse Buzzer) says disconnect green/blk wire from 10pin, jumper green/blk to battery B-. Buzzer does operate, so says replace controller. Does all this sound right or wrong? I知 starting to think it痴 the controller which sucks. Oh, and one more odd thing. Did ITS test, and instead of getting 1.0v at click I知 getting 14.2v, and full throttle I知 getting 13.2v not 2.7v. |

2. Bad/dirty connections, but okay as long as solenoid clicks when pedal is pushed. 3. You said you got 3 beeps when you put controller into diagnostics, so the beeper is working. Not quite sure why you are testing it. 4. Are you sure you are measuring the voltage on the correct wire? J4 Pin-4 ought to be about 15V and J4 Pin-3 ought to vary between ~1V and ~3V. |

Re: 2002 TXT PDS 3 beeps
I'm pretty sure the controller is bad.
Best replacement for it is an Alltrax XCT48400-PDS. |
