Afterwords I plugged in the shore power and turned the main break back on and unhooked the TV ..jacks worked.
Unhooked shore power but left the main break on... jack doesn't work.
Arrrrrg! Trying to avoid running yet another line to the battery but it's looking like I may have to.
Had btthe same symtoms on my 76 ovelander it was the ground fuse corroded. Sprayed with contact cleaner and removed/reinstalled several times, has worked since.
It could be the battery ground connection too.
