shorted out battery on ZZR!! now not starting

[sam.ashburner]

Yesterday:

I changed the battery on my ZZR400 (same as 600 in all but capacity) and accidentally connected the positive terminal to the frame a couple of times, resulting in major sparks! lol

It would start on the button afterwards, and I managed to bump start it on the third attempt, but it ran awfully and kept cutting out for about 10 mins, ran smoothly after that.

Today:

It wouldn't even bump start this morning, and I got two massive backfires in the process! I tried the old battery again to see if it was just the battery I ruined, but no luck.

Now when I turn the ignition on everything lights up for a couple of seconds then goes blank.

I've really got no idea whats going on with it and would appreciate any suggestions, otherwise I'm gonna have to go over all the electrics and clean and re-insulate everything

Thanks

Fried the ECU?

That was my girlfriend's dad's first response but luckily the bike is a 91 bike and consequently doesn't have an ECU. I'm gonna investigate the starter relay and main 30amp fuse.

I just tried jump starting it from my dad's car, with his engine running, and it was as if there was not battery connected at all: e.g. no lights on the dashboard or anything. I think I'm going to go through the Haynes checks for every wire and junction box.

fuse ?

Checked the 10amp fuses in the junction box and no sign of trouble there. Just gonna go out and check the main 30amp fuse now. Cheers

I know it doesnt have an EFI ECU but Im sure it will still have electrical circuitery of various kinds, to control ignition and safety features such as preventing startup when the sidestand is down etc?
