Work horse WH w22 chassis electrical
Need wiring diagrams..schematics, chassis build Dec 2009 RV Thor Serrano Jan 2010 Fuse ..up front under hood...60 amps..keeps going out Feeds sub panel under dash fuse panel All fuses in sub panel...

easier said than done..
first chance you get take a look under the front end of a FRED on work horse chassis
i'm not convinced this is a short
my thoughts run to a loose/broken connection, and the surge of the return to power on "all sub circuits" from the interruption that blows the fuse
IF it was a HOT line power short, removing or changing fuses would do nothing
BUT since removing some of the load, reduced the incidence of happening
i conclude that the lower surge reduces the incidence of tripping the breaker AKA fuse blow out
there is at least one other person with this exact same problem on the same model
which is why i posted the update
the reason for the ABS fuses removal was to test the idea that the ABS was the circuit overload,, since that did not ..remove the problem, but only reduced the incidence, it adds to the conclusion above..
the rate of fuse failure is directly related to the amount of load being interrupted, its the return to service surge that blows the fuse
A/C compressor clutch is an electromagnetic coil aka High surge..when caused to suddenly drop out and then return to full load,
the A/C control fuse does not blow, it is the sum total off all these ACC circuits going off then back on, while under full load that usually causes the failure
i have tried to make it fail during testing but it doesn't happen, it takes a unique set of circumstances
