Notorious Yellow Wire

Recently I purchased a 2005 Winnebago Journey model 34H
I wanted to clean & paint the battery trays
Removed the battery's paying close attention to all connections
After replacement several fuses were blown
All 3 radios , thermostat , generator and back up camera .
All have been corrected and now are operational .
With the exception of the dash radio .Which happens to be a Magnadyne M99000
Which is the only item without a fuse . I have pressed the reset button on the face .
Bench tested the radio and it works .
Now it takes 2 , 12 volt sources to operate . A switchable 12V ( red ) and a constant ( yellow )
I have been through & under every thing in this coach
The breaker on the panel in front has current on both sides I can't find any in line fuses .
I will admit I'm having a tough time reading winnebagos wiring schmatic . ( why does wine use so many yellow wires )
With that said is anyone knowledgable with this dilemma HELP please !

    As per the last two posts
    I have thought of adding another constant source
    Also as mentioned a low source . Yes thats whats been puzzling me
    With repeated probes hours apart sometime I will see 12V also I will see it climb slowly in voltage
    An drop when the key is turned to accessory or ignition
    But all said it does require 2 inputs or it will not work
    I find it hard after all the hours i have been searching & reading It would be a shame to not be able to restore it to original condition . Especially since I'm already naturally grey

    If I remember correctly the yellow wire is for constant 12 volt power with the key in the off position maintaining memory for stations and clock. Very low power draw and as previously mentioned could be tapped into another circuit. Blessings kdk

    After looking this over for a while, I would just cut this wire,tape it up and find a new constant 12V source and connect it via a 1 or 2 amp
    fuse.This will give you less gray hair.
    As for the radio, if it does not have bluetooth and and and, I would
    check out the Kenwood website and find what U like.
    Siggy
