Jonno Raab Posted January 21, 2017 Share Posted January 21, 2017 I bought a wheel Called a MAC-BEYOND Hi Wheel E1. it looks like a rebranded generic X3. First time I started it after a full charge it was fine, next day I pressed the button, lights came on, bleeper made startup sound and then it went dead. Few hours later I started it and it came on but only three lights. Charge it, after a few seconds it's green so start it up and same thing as before, lights on, bleeped making startup sound then it goes dead. There's no way I'm riding this thing til I sort out the problem so I take the cover off. The motor power spade connectors are wobbly so I solder them straight to the board. Then I notice the power connectors are spade connectors but plugged In reverse polarity. I check the battery outputs and they are correct so it's deffo been connected in reverse polarity. Instinct tells me to plug it in properly but logic says if it didn't blow the board I shouldn't change it. Something is deffo wrong here. Can anyone tell me what is likely to happen if the battery polarity is reversed? Is there a diode or something to protect the board? I'm not touching the switch until I get an answer of some sort. Can anyone identify the board? Link to comment Share on other sites More sharing options...
