Hello Hal. My name is Tan.

Does the fuse blow when you trim the motor or when cranking?

Could I get the engine serial number please?

I would say when trimming the motor because when i come back the next day nothing works and trimming was the last thing I did. Serial number is ***** o.

Do this trim the motor up and down does fuse blow? The only things that can blow the fuse are the trim relays, start solenoid(only when cranking) and the rectifier of the charging system. The rectifier and the relays are the most likely. If the fuse doesn't blow when trimming the rectifier is the only thing that will cause the fuse to blow if you aren't doing trim or starting the motor.
