2007 Honda BF90 - hooked up battery backwards - all dead now at engine

[Northerndude]

Hey all, I did the unthinkable and hooked up my battery backwards.

It blew the 30a fuse on port side of engine. Did not blow the 15 A fuse above. I tried to start (after I realized it was incorrect, got battery correct and replaced fuse) and got a relay click sound then all is dead. Can't use the trim to lift engine either. I just get a bit if a scratchy sound out of the small Control Relay box in the back port side of engine. Somethings blown, but I just need some troubleshooting tips on exact places to hit up. |

I have my 12.69v on the main heavy lead coming in and I have it across the 30A fuse.

Any help would be appreciated. Damn i'm a dummy

Funny, I checked the V and I ohmed out all connections. I just had a high resistance open in my + barrel at battery

I had a bad connection inside the barrel on my + connection coming from motor to battery. Just need to replace and solder new connection on wires from motor.

Luck beats skill. EVERYTIME
Paint the TOP only, of the positive battery post... red. And the top of the + cable also.
