Fusible Wire Location

[lfbox7]

I had the power wire for my radio come lose and arced which not only knocked out the radio, but also my defroster fans and my leveling pump. I am 95% sure that I am looking for the fusible wire that protects this circuit. But, I have not been able to locate exactly where it should be. Does anyone have any ideas?

I don;t believe the "WorkHorse" chassis or Winnebago use fusible link wire on their coaches. Mose likely it is a fuse, located under the dash. That hot wire must have been bouncing around for a while. Stil all it should have effected is it's own circuit.

I checked both the box under the dash and the box under the hood. No luck in either. I also checked for an inline fuse, but no luck there either.

I can find the complete wiring diagram for the Winnebago side, but not the chassis. So, I do not know if there is something else further down the line that blew.

And of note, the compass/thermometer is also out, but completely lights up when the key is in the ACC position.

Does the radio work off the house power (when you flip the switch)? Not that that helps find the fuse, but it at least lets you know the radio itself isn't an issue.

lfbox7 which position is the Radio Power Switch? Both fuses feeding the radio power switch are under the instrument cover, see link below.
Wire LS is General Purpose coach power
Wire LD is Automotive Ignition Power

The radio works on house batteries, not engine. I will check the diagram and see if one of these fuses is the issue.

Based on the diagram and on my actual dash, I appear to have the 'IPN' model without the fusible wires. This however does not solve my issue. There has to be some other fuse, not located under the dash or under the front hood in front of the under the dash fuse box, that I cannot locate.

It is effecting:

Radio (on engine switch)
Defroster fans
HWH Leveling pumps
Drivers side powered window
Compass/Thermometer

lfbox7, Check both sides of the Radio_ACC (No 16) fuse socket with the ign switch on and see if you have power there.

grtharris thanks for the tip. I had power on both sides, but I was easier able to trace from the fuse box out and found an added on inline fuse on the line that I had not identified before. Checked the fuse and it was blown... Thanks for your help.
