Just getting ready to get the boat ready for the water, went to start the port motor but in the process the power cable bumped the block and sparked. Now I don’t have any power to the motor. Nothing happens when I turn the key, no click or anything, No voltage on the dash, I pushed the red reset button on the relay circuit. I’m assuming I blew a fuse or fried something? Any advise where to start looking first? Engine is an old carb 502 mag.

is there one of these on the starter its a fuse voltage goes through it to the top of the engine

Thanks F-2 no I don’t have that 90 amp fuse on the starter. Looks like I missed a wire on the starboard motor causing my issue. All good now!
