Alarm going off 1996 Wellcraft

[toomuchclub_1113]

I have a 1996 Wellcraft Excel 21SL, with a 4.3LX Alpha 1. The problem is about 3 weeks ago I left the key in and "ON" but not running. I left the boat and about 7 hours later got a call saying I left the key in and a high pitch whine was coming from the boat.<br /><br />I assumed it was a low battery indicator but this doesn't appear to be the case as the battery is fully charged. The alarm now comes on usually after I run it maybe 20min, stop and re-start. The sales guy at the wellcraft dealer said this was a Low Oil Pressure Indicator, but I'm not buying that....again it only comes on when the engine is NOT running. The alarm has 2 wires coming in to it, it's located just aft of the throttle under a console and is about the size of a quarter.<br /><br />Any Thoughts?

Most I/o,s and outboards have alarms built into them, over temp. being the most common, and Merc/crusier could have a low oil pressure alarm built in. No, leaving the key on won,t cause low oil pressure, but could have damaged the electronic ignition mod., or low oil pressure switch, best have a M/C dealer check it.Good luck, Sting

I've got a 1994 Excel 20 and the owner's manual says the alarm goes off if the oil pressure is low for 20 seconds, whether the engine is running or not. I put tape over the alarm to quiet it and I'm about ready to cut it loose. I've noticed the wire connections are potted into the alarm as if the designers wanted to be sure it stays connected.

Low oil pressure will set it off but if the engine is running without knocking it is not that as it only requires 4lbs of pressure to stop this alarm. The other thing that could be causing it is low outdrive resevour oil. this the most common. Check this do not unhook the alarm this also lets you know overheating, oil pressure, low drive oil etc.<br /><br />You could have fried the sensor have the delar hook up the ddt machine it will tell you.
