    I have a 15 amp fuse in the main AC input. Before the terminal block to power supplies and other stuff. That fuse never blew.. Or Maybe it is a 20 amp? I need to double check that and do the blow test you linked… Should I have additional fuses inline on the 24V DC between the motors and controllers or between the power supply and controllers? Or should my main fuse should have blown?

    That link shows a diagram with 8GA + wire and 10GA Negative wire… Overkill? The controllers can’t even receive 10GA and barely a 12 GA wire.. I’m going With 12 GA to the motors because it’s a similar (Not Smaller) than the Gauge to the motors from factory. But larger than the 14GA I was using… I did upgrade to 10GA with inline fuses from the 24v power supplies to the Controllers. (I had to trim some copper wire threads off the 10GA to fit the controllers)

    The Image also shows a 30 amp fuse?! I Can’t blow the Main AC with a 5 Amp fuse… Holds strong in game with 2 motors, fans, bass shakers and pedal shakers.. Traction loss is still out as I’m waiting on a new controller..

    I have 7.5 amp fuses inline on the positive DC line before both controllers… Im only able to test the one with both front motors on as of now. But need to get smaller fuses if I want to test a blow out I guess… Seems impossible to blow out a fuse when I want it to blow…

    But still after long races the motors are barely warm to the touch.. Nor is that controller for the 2 motors… All I really learned is turn the simulator off after a power outage…. And don’t mess around! add fuses…
