okay I have an 90hp 2002 Yamaha with a random starting issues. I can leave it for weeks and it will fire right up. However a half an hour later I turn the key and nothing happens, but I have full power on the console and the engine hydraulics work. I checked the battery and the wing nuts are tight, but this is driving me crazy. I have my doubts about the wring as their about 6 wires connecting to the battery terminals. Any help would be appreciated.
