OK - here is my issue.
Engine: 2005 - 150hp Yamaha 2 stroke - oil injected.
Problem: Low oil alarm at key is "sounding" constant, while engine is running. Engine goes in to limp mode.
1) Alarm at key appears to work (makes noise), limp mode works due to alarm.
2) Disconnected the engine mounted oil tank harness. Alarm still sounds.
3) Disconnected the remote oil tank harness, alarm quits. (Problem solved, so I thought). I ohm'd the old remote oil tank sensor, and float switch seemed to work intermittent. So, I purchased a new remote oil tank sensor.
While waiting for the new sensor, I learned a couple things:
I removed the black wire, from the remote tank harness, just before it connects to the oil tank sensor harness. This stops the alarm, and also allowed engine to work "NOT in limp mode". The engine runs great, because it does not think remote tank is low on oil. Engine continues to run fine off engine mounted oil tank, until it gets low. When it gets low, key alarm sounds. (which is good)
a) Learned both the oil pump transfer switch works & the oil pump in remote tank works when holding the transfer switch. Does NOT pump oil though, while black wire is unhooked. I can transfer oil from remote tank to engine tank, while engine is running.
New sensor arrived:
Installed new oil tank sensor. Plugged black wire back in connector, and hooked everything back up to stock configuration. Moment of truth...started engine.
4) Damn key alarm is going off constant, and engine is back in limp mode. (New sensor did NOT fix it...grrrrrr!!!)
Now the oddity:
Removed new oil tank sensor from remote tank, hooked up to wire harness, so I could manipulate float, while engine is running. When the float on the sensor is in the "up" position (indicating good oil level). The alarm sounds constant. When float is "down" or indicating tank is low, alarm does not sound.
In my mind. This is working, exactly opposite of how it should be working.
Any suggestions what could be the problem?
Bad key switch/alarm??
Bad harness on the remote oil tank??
Thanks in advance for any help
