See just the聽oil light lit when I turn the ignition key. Normal? Thanks

I don't think so. There should be a light "test" position or button.

Also you should definitely be seeing an "alternator fail" light as the聽alternator is not聽charging while聽engine stopped. Brain escapes what high temp light should be doing.

You should also be hearing an audible聽alarm. This not happening is often related to the peizioelectric(sp?) horn failing - the round bigger "grill" next to the tach. It is fussy but you can replace this.

I have removed the panel on my聽Volvo and carefully removed all the connections and cleaned them. My lights all聽work now but the horn is still doa...

It's bizarre how much "electronics" is packed in that聽control panel. Who figured...

Thanks for the info, I'll see what lights up w/ the test button. The聽alarm works, goes off as soon as the聽engine starts. What triggers it -聽Oil pressure? Over聽heating?

Regards.

The warning horn is for low oil pressure. Until the engine starts or turns over enough to generate oil pressure, the alarm sounds. I don't know what happens with an overheat. The PO disconnected the temperature warning and added a gauge with it's own聽transducer. Unfortunately, the horn didn't sound and the gauge failed when critters blocked the聽water inlet. Had a聽mechanic change the聽transducer back to the stock warning light. Assume it will sound the horn if the engine ever overheats. Haven't seen any light for the temperature because the engine hasn't overheated, that I'm aware of, since switching back to the stock system. Engine made me very aware it was聽overheating when the inlet was blocked filling the cabine with steam.

The schematic shows the buzzer is connected to the high聽water temp, low oil pressure, (and rubber seal on the sail drive if you have one).

There is a toggle switch that in one position lights up the tach, in the other position tests the high water temp light. (This position is momentary if I聽recall.)

Oil and charge lights should be on with key on and engine stopped.

Don't remember if this聽alternator is self exciting or not. If it is excited by the聽battery, it gets that聽current through the warning light. If the warning light is burned out I assume the alternator won't excite and won't produce聽current.
