I just installed my VH pipes and had the power commander hooked up to the ECM and I didnt realize the ecm was lying near the battery. When I started the biked, it turned over and I looked down and a big *** spark was arched from the battery to the ECM......Welp now the bike it dead as a door nail.

I'm hoping the curcuit breaker did its job and I just have to replace it. What do you guys think? I'm scared sh$%less that I fried a lot more and its going to cost me a boatload.

 

To find out if it is a nightmare just make sure nothing is melted and grounding then check the battery for voltage,if so far so good connect the battery and test the circuit breaker for power in and out.Good Luck !

 

I'm afraid your Fu*ked, it probaly shorted out your EMC, if everything is dead. Sorry. I hope I'm wrong.

 

unhook the battery and hook it back up to reset breaker maybe thats all it did

 

If you saw an electrical spark you can calculate the voltage roughly by the length of the spark. The insulation strength of Air is about 50,000 volts per inch or any portion thereof. i.e. 1/2 inch = 25,000 volts, 2 inches = 100,000 volts etc. Your ECM is designed to run on a maximum of 16 volts (the maximum the voltage regulator setting at very low temperatures) and does have some high voltage spike protection on some of it's circuits like the ignition coil, fuel injectors, fuel pump, etc. . . . but sorry to say, nothing on the order of what I suspect you saw is likely to be endured by the computer. Even static electricity (The electrical shock you gave your brother/sister as a kid after shuffling you feet on the carpeting?) is an issue that manufacturers constantly warn their dealer mechanics about. They call it ESD (Electrostatic Discharge). Static that a mechanic can't even feel, can blow good computer's and other electronic components just by touching the box or it's terminals if the mechanic and the computer don’t share the same ground . . . some people dismiss it because they don't always blow the computer when they don't follow ESD control directions . . . but then again you don't get a flat tire every time you drive over broken glass and that's no reason to avoid doing so if you can at all avoid it . . . and fixing a flat is a whole lot less $$$ and a lot easier to deal with than a blown computer.

 

Hey blue! Seriously dude? EMC2?

 

And in layman's terms Blue? You mean he's F**ked.

 

Yup, pretty much . . . if he's lucky he didn't take out the speedometer, the voltage regulator and the alternator diodes as well . . .

 

Ouch, that's gonna hurt!!

 

time to buy a used ecm or a thundermax
