Measuring A1 to A2 is less than an ohm, same for F1 to F2, so everything seems normal there. I bridged F1 to A1 one last night and then hooked up F2 and A2 to a bench power supply dialed to 50V 20A, and the motor spun, and upon inspection the brushes look OK, almost new judging by the amount of meat on them. Sometimes just spinning the motor by hand a few turns can get it going. You tested the contactor already so you might just have worn out or dirty brushes on the motor. The controller is sensing open circuit on the motor. I'm pretty sure the codes will be the same on yours.

Still expensive but maybe less than the OEM Sevcon.Д«ut I found a manual for a similar Sevcon:ДЎ0.2.5Diagnostic LED - This is mounted between the connectors on the front of thecontroller. It would take some rewiring to fit the connector on the Alltrax. XCT 48500 would be a 48v, 500A that would work with your motor. Might cross post this in a general area too.

I've pulled it apart and it's full of that black potting epoxy, so I'm going to have a hard time getting to the innards to try and repair it otherwise. If I was to buy a new Sevcon, would it need to be programmed also?Дoes anyone maybe have a good one they are selling? I think these work by switching things to ground, vs switching to positive, so not sure if I can change to another brand of controller. Does anyone know where I can get one of these affordably? Most seem to be around $700-1000USДЄre some of the other visually similar models interchangeable? So it appears that I have a faulty Sevcon Millipak controller. It's now just giving 3 flashes which indicates it is likely faulty So it seems the Sevcon isn't outputting a contactor charge to energize it. Tried bridging the 2 large terminals on the contactor to allow current flow but this didn't work.ДЄpplied 48V to the contactor and it clicked over fine and reads 0 ohms when energized, so it appears OK.

My girlfriend parked up the kart yesterday and then went to use it later in the afternoon, it makes all the right noises (reverse beep etc) but the main contactor doesn't click on, and getting 4 flashes on the dash.
