    2007 Stolen, Electrical Problems

    Hey all,
    Had a pretty bad week last week and had my beloved 2007 FZ6 stolen but recovered last week. Some homeless folks cut the main ingition switch harness and tried to joy ride but couldnt get it going and gave up... not before they replaced my battery with an incorrect hunk of junk and spray painted her purple

    Anyways, I want to see if I can get it running again but am worried the ECU might be fried and if thats the case, I cant really sink any more money in it.

    So where I'm at now, I spliced all the ignition wires back together and she come on electrically. Fuel primes and everything. Neutral light does not show when it should. Does not crank with clutch in. Fuse on top of battery blown and replaced with 15A.

    Thought maybe the neutral switch was bad so I jumped the connection under the tank. Neutral light comes on and cranks but no fire.

    Is there any way to check if the ECU is fried? If thats the case, Im not sure what to do but I'll sure be out of a lot of money..

    Thanks for the help and advice ahead of time!

    Did forget to mention that I accessed the diagnostic mode and got codes 19 and 30.

    That sucks.. (at least you got it back)..
    @Motogiro will post and give you an idea what to do however, there are many bikes being parted out.

    A used ECU should be able to be found for fairly cheap... Check the F/S section or Flea Bay



    *Both codes point towards the ECU:

    Pretty solid confirmation that the ECU is done then? Would the neutral light issue have anything to do with it? I find that odd because I never had an issue with that before and I know they didn;t get it started to damage it at all.

    Higher probability the the starter cut off relay assembly was damaged. About 34 bucks...��

    If you can't fix it by hitting it with a hammer, it's electrical!

    How could I check that relay? And I can get the bike the crank if I short out the neutral signal, not sure if that would come into play. I suppose that relay could have been fried when attempting to hotwire right? That would be really great if it wasnt the ECU!

    BTW @Motogiro, love the Day the Earth Stood Still reference in your sig, need to watch that one again soon!

    Klaatu barada nikto!

    Yes ,Generally, in most cases, the starting cut out relay assembly is damaged when the ignition switch harness wires are shorted. This unit is comprised of diodes and 2 internal relays. One relay for the starter control and one relay for the fuel injection. There are diodes wired for logic that look at the neutral safety switch, side stand and clutch switch to create the safety logic for starting and shutting down or interruption of the engine running, if the side stand is put down while the bike is in gear.

    Here's a link. #24 onb the parts fiche. https://www.ronayers.com/oemparts/a/...1/electrical-2

    Relay Assy (5Vk-30)
    5VK-81950-30-00

    This unit is the same in the S1 or S2 FZ6

    All the best from Klaatu and Gort!

    Thanks Cliff! I'll pull that assembly tonight and see if I can get the relay to switch and get another one on order. Much appreciated! I will check back when I have some info.
