454 are notorious for battery drain
something to do with the starter or alternator
both of my previous MH had 454 and both would do that just setting
yes you can rewire the radio, i did, just find the (2) hot wires, 1 is for play the other is radio memory, and move them, run a wire from the house circuits up front under the hatch
unfortunaely, the emg start relay gets it power from the chassis battery which was dead, so pushing the button did not work
it might have worked if you had pushed it before hitting the key ... maybe
take the hot wire from the rocker/push button and move it to a hot wire from the house batteries, that way it will always work (as long as the house batteries have charge) thats what i did
while your at it
go online and find a 454 hot starter sheild
hot starter restart problems are another thing, they are know for
the starter blanket reduces that problems, keeping some of the exhaust heat off the starter, so it doesnt get heat soaked and lockup
I can explain it to you.
But I Can Not understand it for you !
