Merc115HP ELPTO Two stroke Low Oil Alarm issue Serial No. 1B023978 Trying to determine which item is bad. Low oil sensor, PowerheadTemp/Engine Overheat sensor, Warning Alarm Module or ???
Originally the alarm horn did not work and I accidently ran theSilverQuick oil out - engine stopped, I refilled reservoir and all is OK exceptthe alarm horn near the starter key did not buzz intermittent or steadyalarm. Troubleshot the alarm horn and it in very dead. so I Bought an off brand12V Alarm with Light and replace the it (Purple and tan/blue wires near starterkey).
Now the horn stays "on" Steady as soon as key is turned toon. Merc Service Manual for this engine, page 3C-16 has a TroubleshootingChart. Went through the "Steady - always On" horn areaand it is not making any sense. Here's why: It says to disconnect Engineoverheat sensor BLACK wire and try agaion. It is a tan/blue wire, notblack. Disconnected tan/blue, still Steady ON horn. I have the Warning Moduleunbolted from engine (Module P/N 821889) it has three wires of four inuse, black, red, tan connected to wiring harness, black, red, tan. Also ablack/yellow wire that it not used.
QUESTION: is it possible to check to operation of this warning module?
QUESTION: What if anything do you recommend -- need some advice?
I have not checked the blue wires on low oil float because they are very hardto get to without removing the oil reservoir.
