the voltage regulator aka the volatage capacitator is the gray finned rectangular thingy bolted to the frame under the front plastics. there are 6 wires going into it and it regulates power going to the bike. i have a spare and would like to see if it is doing its job (there are over 100 soldered tiny wires inside it, if there is a break in any one of them, it is fried) and am unsure of how to figure it out. thanks
