2003 90F HP Yamaha has a 20 amp and a 30 amp fuse.
The 30 amp blew - found and fixed carroded connector on red wire from battery to turnoff switch.
Next trip 20 amp fuse blew. Any ideas on what it protects and where to start troubleshoot appreciated.
Thanks,
Additional Info: When 20 amp blew, motor and tilt stopped. no ignition when start key turned.
Replaced 20 amp fuse and motor started but no electronic will turn on.
 
See my reply to your first thread. Makes sense, the fuses protect the starter and PTT. You must have a bad ground somewhere causing the overload.

Next post you make, keep everything in one thread, including updates.
