Yama 130 Erroneous Alarm

[scubafish]

I have a pair of 130's that I get an audible alarm with no indicators. Seems to take a few minutes and only past idle, when I return to idle it goes away. I have it narrowed down to one of the engines. I have disconnected the temp sensors and the oil levels are OK. Switched oil module. Indicators for level works fine at both tanks. I recently had to replace the remote pump. Any suggestions? Lots of hours on this motor

1995's ...Digital Tachs with the 3 arrows indicating oil, temp, etc.....alarms sound, cut RPM's on both engines but no arrows are indicating. When I fired it up today, ran it down the canal at cruising, it alarmed in a 200 yards or so and then every time I ran it past idle...When out this weekend I had the same scenerio, stopped offshore, disconnected the battery to the engine in question and then after an hour or so ran back in 4000-4200 for a mile and then 19-2200 for a few miles and it sounded. Once it started, It sounded anytime I went past idle. Seems thermal related, but may just be a bad connection. Is anything tied to the alarm circuit other than the 2 temp sensors and the 2 oil floats? Thanks for the help

hello<br /> look to see if the gray wire at the 4 pin trim harness in the engine is connected.<br /> then test the overheat alarms by grounding the pink wire while the key is on and watch the tach.<br /> if its alarming it should give an indication.<br />you may wish to buy or borrow a temp gun to insure the engine temps are normal. when was the last oil filter change in the remote tanks?<br /> good luck ands keep posting

Re: Yama 130 Erroneous Alarm

Both filters are new, Oil flow is good, Done the pink wire grounding, it was fine, will check the gray wire in the AM. I drained the main oil tank and noticed the foam seal was not in place and intact, so I removed the oil line to the pump and cleaned, reinstalled and bled the pump. Did not find any debris or obstruction.<br /><br />Kitty Hawk, huh? Got a good friend up in that area at a reuinion. From Kinston originally, but in Lauderdale for years.<br /><br />Quick response.
