    Chaos 1600w mosfet replacement help needed

    The 6 mosfets I’ve marked in black do seem to be faulty, I tested them incorrectly last time using my negative lead on the gate / drain and positive on the source when, as I did in the first place, it should have been the other way round. There is no power from Gate to the Source whereas on the...

    I just checked to see if there was resistance not how much there was. I’ve checked the wires but all seems ok and no I didn’t drop it.

    Just noticed this on the back of the controller, this is the soldered joint where the negative lead comes in from the battery. Would this be an issue?

    Could the phase wire sequence go wrong? Everything was working ok before this happened and I hadn’t had anything out or changed any settings etc. The only thing I was doing was transferring the battery from this to my daughters buggy and back again. The controller has never been moved, it is in...

    Chaos 1600w mosfet replacement help needed

    Update..... So I’ve put new batteries in my multimeter as it wasn’t giving correct results for mosfets I knew to be working. Re-tested the old ones and they’re all fine :mad: not sure if it was down to the meter or not but miraculously they are working. So, were to look now? The motor still...

    Hmmm, so they might work but aren’t necessarily suitable for this application? I’ve also a full set of the mosfets in the picture below, they came out of a 24v 110amp controller but I can’t find the specs on them anywhere.

    Chaos 1600w mosfet replacement help needed

    Just looking at the prices of the fets you suggested, the cheapest place I can find ‘RS Components’ they’re £4 each, so if I replaced all 12 I’m looking at a bill of nearly £50! I might as well buy a 2000w controller from flee bay for £60 :(

    Chaos 1600w mosfet replacement help needed

    It’s running 48v 4 x 12v 12a batteries. They don’t have lcd displays just a basic red, orange, green battery power light near the throttle. I was thinking of taking it up to 60v or 2000w of power but for the difference in speed to cost etc it’s probably not worth it.

    Firstly, I know this is an Electric scooter but I’ve found this site really helpful with my bike and everyone on here is very knowledgeable, so I’m hoping someone can help out. My Chaos 1600w stopped working the other day, the motor would jutter a little as though it was going to spring in to...

    CYCLAMATIC CONTROLLER REPLACEMENT ISSUES

    Quick update. I've stripped the throttle and brake down and this is where the wires go. Red and Yellow both go to the pas button Black and Blue go to the throttle Orange and Grey to the front brake 'they're cut off already from factory' White goes to rear brake Green goes to power lights I'm...

    CYCLAMATIC CONTROLLER REPLACEMENT ISSUES

    I think it's likely that the PAS wires are incorrectly attached to one of the throttle wires I just don't have a clue which wires are which and I can't find anything from Cyclamatic to tell me which wires are which. If I had a diagram I could try with the box to link the correct wires. I don't...
