The resolution to my issue with the 5 amp fuse blowing repeatedly is a new ECM.

Blows at 1 turn to right.

Flip battery disconnect ON, radio comes on, bilge pump works etc. when turn key to right, used to get warning beeps, but no now. Replaced 5 amp key switch fuse, but it blew again. Do you think I have bad ignition relay or something more sinister?

Well that didnt work. I’ll check cable connections - thanks

Battery good and in neutral. Trim down. Battery disconnect switch on. Hear click when switch turned on. Insert key and turn to right. Radio light comes on, bilge pump etc work. But no engine clicking or turnover. Ideas?
