Wiring




It's been a while since my last post, but it's not for a lack of working. After painting the battery tray, I reassembled the bike and started in on the wiring. With so many batteries, this is a huge undertaking. The picture above shows all of the ancillary bits that connect between the battery pack and the motor. At the top is a high current, keyed switch. I added this switch in after deciding the contactor by itself was insufficient. The contactor is to the right of the switch, with the metal band around it. It is an electrical switch, or solenoid, that is actuated by the motorcycle's ignition switch. As recommended, there is a 1000 ohm resistor across the main contacts. I found that this resistor got hot when the contactor is open (whenever the bike is turned off). To the right of the contactor is the main fuse. Below all that is the controller, an Alltrax AXE-7234. This controller is pretty sophisti-ma-cated, allowing you to program a number of parameters on your computer.
