justtried it. it didnt light upand ow i only have 4.62v on the + of coil and millivolts on the -... does that mean i fried coil? also since i only had 4v i jumped a wire rom battary straight to + of coil to assure 12v was there and nothing.

Will need to ohm test the coil, I have the specs, but not here. Do you have shop manual?

No, it's long lenghtways.Coil numbers seem low.

What you described is the neutral safety switch AND backup light switch. The ignition switch is rectangular and lays on the top of the column lengthwise. Wiring harness attaches on the lh side, as I recall.

72 inline 6 . Go back and read carlnut50 post and check it out that way. It is not that complicated.

Sorry, I couldn't find coil specs for a '72 model. These are for a '70 model. Primary 1.0-1.7 ohms and Secondry 6.5-14.5 ohms.

With all due respect, every time I've tried to "ohm" an ignition coil OR suspected one was weak and replaced it . . . no change. Even when I ordered an AC-Delco one, it came with NO stampings on it, just an inked number on the bottom. Also, NO "Delco" logo anywhere to be found. This leads me to suspect that all ignition coils usually hit the same general resistance specs so they've all been consolidated into ONE product from "over there". Only the connections/terminals might be manufacturer-specific, I suspect.

I don't know if my suspicions are true and accurate, but it wouldn't surprise me if they were.
