Re: 2002 DS 48v Series NEED HELP!
Even better is there a service manual on line somewhere??

TEST 3 Check the potbox circuitry The following procedure applies to the standard throttle input configuration for these controllers, which is a nominal 5kΩ pot connected as a two-wire rheostat (0 = full off, 5 kΩ = full on), and also to 5kΩ–0 configurations. Some 1204/1205 controllers are sold with other input characteristics. If your installation uses a controller with a throttle input other than 0–5kΩ or 5kΩ–0, find out what its range is and use a procedure comparable to the one below to make sure your pedal/potbox is working correctly. 3-A With the keyswitch off, pull off the connectors going to the throttle input of the controller. Connect an ohmmeter to the two wires going to the potbox and measure the resistance as you move the pedal up and down. The resistance at the limits should be within these ranges: RESISTANCE (in ohms) STANDARD 0–5kΩ POT 5kΩ–0 POT Pedal up: 0 – 50 4500 – 5500 Pedal down: 4500 – 5500 0 – 50 3-B If these resistances are wrong, it is because the pot itself is faulty, the wires to the pot are broken, or the pedal and its linkage are not moving the potbox lever through its proper travel. Actuate the pedal and verify that the potbox lever moves from contacting the pedal-up 30 Curtis 1204/1205 Manual, Rev. C 5 — TROUBLESHOOTING & BENCH TESTING stop to nearly contacting the pedal-down stop. If the mechanical operation looks okay, replace the potbox. 3-C While you have the potbox wires off the controller, use an ohmmeter to check for shorts between these wires and the vehicle frame. You should see a resistance of at least 1 megohm. If it is lower than that, inspect the wiring for damaged insulation or contact with acid. If necessary, replace the potbox. 3-D Push the wires back on the controller terminals. It doesn’t matter which wire goes on which terminal. 3-E Inspect the terminal area of the controller closely. Occasionally a buildup of dirt or acid residue of a conductive nature causes electrical leakage between the throttle input terminals and the B- or M- terminals, leading to faulty controller operation. To check for this problem, measure the voltage at the appropriate throttle input terminal (upper for 0–5kΩ pots, lower for 5kΩ–0 pots), by connecting the voltmeter (-) lead to the controller’s B- terminal. The keyswitch must be on and a direction selected for this test. ACCELERATOR INPUT VOLTAGE (in volts) STANDARD 0–5kΩ POT 5kΩ–0 POT UPPER TERMINAL LOWER TERMINAL Pedal up: 3.8 4.3 Pedal down: 9.5 10.2 Compare your readings with these; if they are different by more than a few tenths of a volt, contamination is probably the cause. 3-F Carefully clean off the terminal area of the controller with a cotton swab or clean rag moistened with water, and dry thoroughly. Be sure to turn everything off before cleaning. Now test the controller to see if proper operation is restored. If so, take steps to prevent this from happening again: dirt and water must be kept from reaching the terminal area of the controller. If the voltages are still out of range, the controller is at fault and should be replaced. |

Re: 2002 DS 48v Series NEED HELP!
Test 3-A easy enough, I pulled the yellow and green wire and hooked up the ohm meter. Pedal up and pedal down readings were off. As I moved the pedal the readings just went crazy. Even holding the pedal half way down and not moving the resistance jumped all over the place. Looks like the MCOR is definitely bad mo money mo money!

Re: 2002 DS 48v Series NEED HELP!
Ok went to Walmart got a high dollar(10.00) analog meter. Readings were not good at all. Picked up a new MCOR, long story short the cart works great now. If you have to install one of the new conversion kits make sure the pin goes in the plug, they seem to move pretty easily...
