We have a Razor MX500 version 2. We purchased a 36v 800w controller as the old one was dead. The issue is that the controller has a power connector with 2 pins (red and black) while the bike's power connector has 4 pins (large red/sm red/ large black) so the connectors don't fit.
What can we do? I tried removing the connector from the old controller and inserted the two wires. So a 2 pin male connector into a 3 pin female connector. It burned the fuse.
Would love some help. Thanks
Please let us know if you have any questions.
Honestly that seems a little more than I can handle. If I return the controller that I have now, can you suggest a different controller to buy. We are seeking more torque and speed from stock. We are not sure if our unitemotor MY1020 is a 500 or 650 w but wanted to squeeze a little more out of it. Our MX500 is a version 2 and we have the 4 pin throttle with it. Can you suggest the best controller to get with this setup? Hopefully with the 4 pin throttle, if not please suggest the correct one to use to be able to plug and play with a little muscle.
Please let us know how it goes.
