Buy a factory service manuial. Go Beg a dealer if they still have the
books to copy the page for you. Find someone with a mitchell 1986 wiring
book for GM trucks and beg them to copy the page for you.
Tried the dealer (local) already. They don't keep anything that old, (old??,
I'm 64). I used to have all those old
Motorist Manuals, but mine are gone too. Just thought there might be someone
around who still had them.
Thanks for the suggestions, I suppose we'll run onto it somewhere.
Friend of mine and I both had 80 models, his was gas mine was diesel. His
dual tank switch quit working, he bought a new switch, that didn't fix
it.....bought a new transfer valve , didn't fix either.....several days
before all this he remembered his dome light quit working.....checked and it
blew the fuse.....replaced fuse to dome light....guess what.....dome light
and transfer switch worked also!!!!! He bought the new switch and the
transfer valve for no reason, all he should have done was check the fuse
box! The diagram and fuse instructions didn't even show the transfer switch
being on the same circuit as the dome light! just for your info as your 86
is probably using the same or similar diagram.......Mark
