"Got a 1974 volvo penta MD1B,
"Got a 1974 volvo penta MD1B, and the "warning lamp for oil pressure" red light on the instrument panel has stopped lighting in the pre-combustion when i turn the key switch. it worked correctly (on when key is switched, then off when engine starts), then i did an 8 hour run of the engine, now when i turn the key switch the oil pressure warning light doesn't come on. i periodically checked it during the voyage and the light never came on, and engine worked well. got a little black oil in the bilge (this engine is new to me, so not sure how much is normal), but oil level is ok (though oil is a season old). there is no oil pressure gauge. i haven't tried to restart the engine.
after changing the oil/filter, and cleaning the strainer, i assume the first thing to check is the bulb itself.... and after that? oil pressure sensor? where is that sensor -- i can't find it in the workshop manual - - and how would i test it?
i'm pretty much a novice so any help appreciated. thanks."
