I was having trouble push starting my bike after the winter so I decided to just have someone jump it with their car (apparently I should have checked here first). When I connected the jumpers, the bike lights and everything came on fine. But, as soon as I hit the starter button it sounded like I blew a fuze and everything instantly died. No lights, no nothing. Even though the bike was still connected to the car, I couldn't get ANY power. I figured I just blew some fuze, but they are all fine. Then I checked my connections and everything seems to be ok and nothing is loose or burned out. So......it seems like I probably fried my ecu. Any other thoughts before I go and buy another one?

 

Was the car running when you jumped off of it? If it was you just blew your bike up. You can jump it from a car but it has to be off.

 

yea, running (feeling stupid)

blew my bike up meaning.....ecu? or something else?

 

Depending on your bikethere may be two places for fuses, maybe you only checked one of them. Also I have had fuses that looked good, but were really bad. I hope it is isn't the ECU, good luck.

 

did u check the fuse under the seat.

 

Also...before you go and get a new ECU try a different battery.

 

Jumping from a car shouldn't have fried anything. 14v DCfrom a car is the same as 14v DCfrom a bike. It doesn't matter what the source of the voltage is as long as it is correct. The battery you use could be 1 million CCA and it wouldn't matter. The bike will only use the amperage it needs. (did you actually connect the cables correctly?)

I agree with the others who said check for fuses.
