Customer Question

I have a 2013 Yamaha four stroke with electric start. Did a stupid thing trying to do more than one thing at a time. Swapped battery and hooked up post backwards. Sparked when hit ignition. Can't tell if fuses are burnt or not. What's your thoughts besides this was stupid? Fuse? Battery? Battery is 2 yrs old and I did have to charge it.

Take each fuse ont one by one. Hold them up to the light to see if any breaks in the material can be detected. Is the engine still sparking when you turn the key, or what does it do?

Fuses are inline and cannot be removed without cutting and crimping back looks like. No, it only sparked at battery once then I fixed wires on battery. It does nothing. Hadn't started in a few months and battery was at 65%. I charged to 90 and tried again but still nothing.
