Yanmar YM oil pressure alarm failure
The latest is that I jiggled everything I could find both on the engine block and on the back of the instrument panel, and nothing worked to restore the alarm.
The next day, however, and ever since, the alarm (and light) has worked. So if I take it in, it will all be working and they won't want to fiddle with it.
Where is the oil pressure sensor on the block, anyway? I can follow all sorts of wires - sort of - but can't convince myself which one is which and can't find a diagram of it. 3YM20.
