[PSUBS-MAILIST] question

[Alan James via Personal_Submersibles]

Rick, the easy option is to take the 3 wires off the potentiometer & switch them around turning the pot on each change. Take you 10 minutes. If none of those combinations work then it could be the pot. You could switch it out with your other one. If it doesn't work with the pot that you know is good, then you would need to look inside the Motor controllers. Check that none of the wires are disconnected or broken. Cliff gave a good description of how they work with the mid position on the dial being off.Let me know how you get on.Alan

Rick, you can just try out the wires in different positions, you won't do any damage.Normally you have a black & a red wire & they go on the far left & far right pin, and a coloured wire goes on the middle pin. Start with the coloured wire in the middle first & change the red and black.If that fails you can check that the potentiometer is working with a multi meter.If you put the probe of the meter on one of the outside pins & the other probe on the middle pin, you should see the voltage vary from 0 to 5V. Or sometimes 0-3.5V.You could look inside the black box & see if the wires have come off in there.All the best.Alan
