Question for you guys whose dash lights are hooked up properly. When you have the key in the run position, just before you turn it to the start position, which warning lights are on in the dash? Should it be Oil only, Gen & Oil, or all three (Gen, Oil, Temp)? For me it is usually only the oil light. My temperature sending unit is not hooked up (another one of those pesky little tasks), so I've never seen that one come on.
Gen & oil lights will be on. The OP sender is grounded w/o oil pressure & turns the light on. When the car starts, oil pressure opens the ground, and the light goes off. The Gen light get 12 v from the fuse panel & is grounded through the alternator. When the alternator spins & makes 12V, it sends 12 v on both sides of the lamp & it goes off.
