Wiring or fuse short

[Badger LLB]

I have a 2250 EL. It recently has electrical circuits that fail. I have Nav and depth finder(live well) circuits that work,but no power to docking lights and horn. I have only partial power to radio/cd. The radio face plate lights but no speakers. I have looked at the radio fuses-all good. I found a 10 Amp fuse that was also good. Are there other fuses to check? To other places to look?

look at the battery, there should be a fuse located on the positive side.

1. Meter the battery, 12vdc or better If not charge and check the battery.
2. Meter the input to the head unit. Seems odd to have “partial power”.
3. Start checking connections and terminations. Look for evidence a critter might have got to wiring somewhere.
Get thru that and if you haven’t found something post it up
Good luck.
