Model: XB-600, Power: 60 volts=5x12 volts ), Charger: Teking 60v., Shunt Mod.: Yes
I saw this site before I bought my bike used three weeks ago, but I didn't think that I would get here this fast!
I am struggling with a problem in the electrical system. I left the charger on for 36 hours (shuts off when batteries are charged). I suspected a problem when I only saw one red light on the charger—should have been green. When I went to turn the ignition switch on there was a popping sound (I assume the 30a fuse) and then nothing.
I replace the fuse and as I was connecting the last battery, the connection sparked and I blew a second fuse. I measured the impedance across the charger plug on the bike with the battery disconnected. It measured 0 ohms. I see no evidence of burned/grounded power wires, indicating that the controller power impedance is 0. I would have expected it to be infinite because the ignition was off. Does this indicate a fried controller? I haven’t disassembled the controller to find out, but that seems like the next step.
Your thoughts? Thanks in advance.
