I'll give it a probe next time i'm out. Owner is just a little paranoid after we found the warning buzzer had been removed by a previous owner and then the fluctuating gauge on his weekend away. We get the test alarm when switching the ignition on and the gauge is fine now but would be nice to...
yeah, it was the gauge wire that lead me down this path. Owner had a fluctuating gauge, turns out the plug had come loose and the only thing keeping it on was the fact it was trapped by the knock sensor. Was unable to remove it as it's totally trapped by it, anyway, once fully seated gauge is...
Ah, no. I meant the oil pressure switch, the 3 pin one next to the oil pressure sender for the gauge. If that's disconnected should that trigger an alarm or is it normally open and would have to be shorted to trigger it?
No, it's not on the drain plug but it does appear to be screwed directly into the block, it's tight against the oil pressure sender, so tight in fact you can't remove the single wire plug that slides onto the sender. he's my photo realist rendering, I'll take a pic next time I'm passing the...
Can't tell the colour. It's got an old black dirty sheath over the actual cable. It's a single wire bolted to the top. It's not in the manifold, it's in the block next to where the 2 oil pressure senders are. The pressure sender with a single wire and the "I presume" oil switch which has a 3 pin...
I'll get one next time I'm working over my his mooring. Also, with the oil pressure switch for the ECU/fuel pump, should that trigger an alarm if disconnected?
Ok folks, had a dodgy oil pressure gauge. I went out to the boat to see what his problem was. Turned it just a dodgy connection on the sender but there was another sender on the block forward of the oil pressure sender and so close that the gauge sender plug although loose couldn't come off and...
Ah, I just stuck one of my standard 12v control panel buzzers in there. The wiring was as you said but the buzzer was missing. When I turn the ignition to the on position the buzzer sounds once. I presumed it was a single one just for a test. Is the single activation an error code?
