2004 70HP 2 stroke battery wired up wrong (!)

[xfixiate]

Hi
Existing boat, ran fine.
Stripped out the garbage wiring, took out everything not in orginal harness.
Brother in law connected up battery to wrong posts, and it was sparking, he reckons it was OK.
After a couple of minutes wondering why things not working, realised error.
Battery is fully charged, but, there's nothing happening either at the motor end (tilt) or console end.
No spakring either.
I've obviously blown something, but I'm buggered if I can find it.
I have run a wire direct from battery to starter etc and motor tries to turn, same to tilt switch it works, but soemthing is wrong.
Any assistance greatly aprpecaited. I've looked at the wiring diagram and can't work it out.
Thanks
John

If that is a Suzuki look on the starboard side of the engine, up high, for a fuse or resettable circuit breaker.

If it is not a Suziki, tell us what it is.

There still ought to be a master fuse (about 20A) or circuit breaker on the engine somewhere. There might also be a master 12V fuse in your boat wiring.

step#1 find the starter. #2 follow the starter wire to the starter solinoid. #3look at the solinoid post that has the batery power to it(oposit the starter wire post). #4 there should be a 20 amp (agc) in-line fuse that feeds the dash. i hope that is the only thig blown! good luck!
