I have been working on my 646LBH and and having a problem with the wiring, the oil pressure light does not come on when the key is on and engine not running. I have done a lot of rewiring and everything else work. The oil pressure light was green and wasn't hook up when I received it. I replace the light with a red one. I wire it from the sender to one terminal on the light, and ran a wire from other terminal to the ignition post on the switch. I am thinking the sender is bad. Can I replace it with a standard automotive sender? :fingerscrossed:

Thanks,
Ted

from what i see in my manuals, with the engine running
their should be a closed circuit through the switch to ground.
good luck. boomer

If I read this right then the light would be on at all times the engine is running. Am I correct in this assumption?

Oil pressure light on.
No oil pressure light off.

On mine, the light is on when I turn the switch on. When the engine fires, and the oil pressure comes up the light goes out. Hope that helps.

Is the new light an LED? They are polarity sensitive. Try to swap wiring at the light...

You want sender with 4 pound spring its more universal than automotive used mostly on hour meters its called oil pressure switch, sender used with electric gauge. This pressure switch supply's ground for lite ease way to check pressure switch is to ground wire on engine block at pressure switch location with key switch on if lite comes on pressure switch is not grounding on inside.
