The easiest way to check an oil pressure switch is to disconnect the wire from the pressure switch, turn on the key switch to the "RUN" (not START) position, and then ground the wire. The buzzer should buzz. If not, then the problem is somewhere in the wiring harness. Assuming that you then hear the buzzer, then the switch is likely bad.

I have a question about my newly installed 2GM20F. I just installed this engine last month. It came with its own electrical panel and looms. It was a good running take out, from another sailboat The Buzzer in the old engine I took out would sound the second I turned the key on. Once I pushed the start button and gained oil pressure the buzzer would turn off. The new engine does not do that? I am afraid to run the engine long as I may or may not have oil pressure. So here is the question. Is there a way to check the pressure switch with a meter? It screws into the block just under the oil filter base and has one wire connected to it. I know the buzzer is good. It will sound with the toggle switch on the interments panel. So I need to know if there is a way to test the switch. And please explain step by step. I know nothing about electrical stuff. I am trying to learn and I am reading a lot of books and watching u-tube how to vid to try to get better at it. Thanks for your help. Capt.
