The fuse in the picture


I was driving the boat after a day on the lake when i heard my ignition sound the beep sound. After investigation (ill spare you all the details) found this fuse popped which I thought was for the trolling motor. It seems it also controls the tilt trim gauges and ignition. Does this seem correct to you or did someone have fun with the wiring on this boat?? This is the second time I have had the boat out.

By "ignition" I assume you mean the keyswitch? as opposed to the engine ignition system (coils, spark plugs, stator, etc)?

The gauges, TNT & keyswitch would ordinarily be on a 20-amp fuse, which I'd be looking for on the powerhead near the main harness plug. I guess if the person rigging the boat wants more devices on that switched circuit (hot only when the keyswitch is "on"), they might increase the fuse feeding 12V to the keyswitch, and hopefully increase the wire gauge accordingly.

I wonder if the main wiring harness fuse on the motor is still in place?

T/M is usually on a circuit breaker, and better be more than 20 amps.

The alarm sounded when the fuse blew? That's pretty fancy.
What boat and motor is it?

Yeah the little beep you hear when you tirn the key. The fuse which is locatedunder the cowl is fine I checked it. I have yet to find a normal fuse box on this boat. The fus eim talking about is in the picture by the trolling motor.

that is the forward tnt switch so you can trim up or down from the bow, it sounds like it is in series and if so when the fuse blows you lose tnt power.
if this is the case you need to find out why the fuse blew in the first place and go from there.

thanks hop. I doubt im gonna be able to ever find any wiring schematic on this boat so looks like its time to make my own.
