I have a 250 Rebel, and there was no ignition when we got it, so we put a car ignition on it. The key turns off the electrical system, but it won‘t kill the engine. That‘s not the problem, though. Ever since this ignition was put on, the battery drains while it‘s running. Dad seems to think it‘s a short. What‘s wrong with it?
Sounds like it's wired up incorrectly, causing a mild short or an open circut, draining the battery.
Standard auto ignition switches have accessory, off, run and start positions. Since I doubt you have a radio or power windows on your Rebel, you don't need to use the accessory position. The ignition system, charging system and lights all need to be connected to the run position. Since you have a separate starter button, you don't need to use the start position either. I'm not familiar with the electrical system on the 250, but something's fishy here. Since the charging system doesn't charge, at first glance it would seem the alternator isn't being energized. If it's wired correctly, since the key energizes the ignition system, the charging system should also be energized. In addition, switching to the off position should shut everything down including the ignition and charging system Maybe someone else here knows, but if the 250 uses a magneto instead of battery and coil ignition, that would explain why the the engine doesn't shut down with the key in the off position. Switches for magneto ignitions differ from those commonly used for battery and coil systems. With the former, when the key is turned off, it grounds the ignition to the frame, causing the engine to die. On the latter, when the key is off, it's isolated from everything including the ground. If your bike does have a magneto system, you'll need a switch like those used on many less expensive riding lawnmowers.
You put a car ignition on it. Whatever that consists of? It's wired incorrectly and like your installation you don't give enough information to trouble shoot it. Start looking for a wiring diagram. If you can read one it will help guide you.
