Re: 91 marathon controller
Ok so far I have completed the following test on my cart.
1. Pot box wires show 0-7.9 ohms as I push the gas down. Pot box ohms move smoothly from 0-7.9 and there is no jumping. 2. Pack voltage is at 38 after a day or so of not being charged. 3. I put the multimeter on the packs main neg terminal then took the positive lead and placed in on the M- on my controller. With the cart on, and the F-R switch in F, I then hit the gas until the solenoid clicked. Voltage was 0 at M- before I hit the gas, but once I hit the gas my voltage at M - was 38V. 4. After noticing that my voltage was at full pack voltage on the M- terminal, I then gradually pressed down on the gas to see if my voltage dropped down to 0. Upon pushing the gas down, the lowest my voltage got to was 33 volts. It never dropped all the way down to zero.. 5. Attempted to trace the high current circuit by putting negative terminal on the multimeter on the main pack negative, and then moving the positive to the M-, C and B on the F/R switch, then the S1,S2,A1, A2 on the motor, then the control side of the solenoid, the and finally to the battery side of the solenoid. The test was done by pressing down on the gas until the solenoid clicked, and then reading the voltage at all the points.. The result as are as follows: M- = 38 C. = 38 B. = 38 S1. = 38 S2. = 38 A1. =38 A2. =38 Control side of solenoid = 38 Batt side of solenoid read 38 volts constantly without having to press down on the gas. When I did hit the gas I got 37.5. Ok I got all this data and no clue how to interpret it. I have read on this forum that test 3-4 indicates that my control box or my pot box are bad. Can anyone please help me to determine what I need to do or what exactly is going on with my cart. Money is tight right now, so I don't want to waste it on parts that I don't need and that might not fix my problem. Thanks again for any and all your help. |
