1970 cutlass no power after motor swap
Hey guys.
so I recently got done doing a motor swap on my 1970 olds cutlass and I went today to hook power up to the car to bump it over and I got nothing, no lights no horn nothing inside Or out side the cab. Did I miss a wire or something? I got the purple and the main power wire hooked to the starter and I cant get nothing to come on the battery has 12 volts so I’m really stumped on what’s going on

Two questions:
1) did you put another Oldsmobile engine in it? If not, tell us what's in it so we can do proper diagnosis.
2) do you have the 1970 Olds Chassis Service Manual that has the wiring diagrams in it? If not you need one.

Took my opinion a bit too literally...
I have (what I call) a dead battery - won't turn the engine over, just clicks - and it registers 12 V on my MM. I didn't mean dead dead dead really. A fully charged healthy bat registers well over 12 V.
Some folks might think a 50% discharged bat measures 6V, 75% discharged measures 3V, and so on. That is not the case.
