2004 DS Series cart - bad controller ?
I just picked up a 2004 DS 48volt series cart not running. Curtis model 1204-410 stock control. The PO said it was fine came out to go again and nothing. It has 2 yr old Trojan batteries, full pack charge 50.8. The solenoid clicked (engaged) when I got it, but replaced with a new one to be sure. The OBC is functioning as it should, I have checked the output of the MCOR at the controller and it is good and changes smoothly with the pedal. I have checked all of the microswitches- all good. When I check the control from B+ to M- key on in FWD with pedal not depressed I read 40.7 volts and when I depress the pedal it goes to pack voltage. From what I read in my Curtis manual - the control is bad. Any confirmation or advice from those much more experienced that me would be greatly appreciated.

You could have a problem with the forward/ reverse lever. A corroded contact or loose cable could cause what you describe. You would still see pack voltage between B+ and M-. |

Yes - the voltage is before the pedal is pushed. It also reads the same voltage with the key off. The Curtis manual says it should be 0 voltage. I read the same voltage at the fed/fev switch.

Disconnect the wires to B- and M- and check for continuity (resistance) between those two terminals. You should no continuity between them. Also check for grounds in motor and FNR lever contacts. I believe your controller may be defective if you don't find a ground somewhere else. Series cart experts may jump in here to agree or disagree with this diagnosis. |
