Got it. There are 3 things that will cause the alarm to go off on this engine.
1. Low gear lube, or a bad gear lube sensor in the bottle.
2. Engine overheat or a bad temperature switch.
3. Low oil pressure, or a bad oil pressure switch.
The gear lube sensor is in the bottom of the bottle. The temperature switch is at the thermostat housing. The oil pressure switch is located down near the oil filter. The wire colors for the oil pressure switch and the gear lube are tan with a blue stripe. The wire color for a temperature switch is yellow. All you would need to do is start the engine up, duplicate the alarm, and then when the alarm is going off simply disconnect each of those 3 sensors. Whichever one silences the alarm is going to be the bad sensor. Does that all make sense. That is where you stand on your end and what the problem is. I think that should do it but I work for tips so I do want to make sure you are happy with my service before you go. If you had a further question on the issue by all means feel free to ask. If not, Just in case you do not understand the way the website works (and some folks do not). You do have to put forth a positive rating in order for it to credit me for helping you. When ratings are not done, the website simply keeps your deposit and they will not credit me. The ratings box is located at the top of the screen. To rate, you must select the star you wish and also confirm it. Please let me know if you run into any problems or errors when trying to do it. If you do have a problem, or if you can not see the ratings box which is at the top of the screen. Please reply back "I rate Jason's service _______" and fill in the blank.
Please note that our question sessions never close out, so if you need to come back later down the road with follow up questions to the issue, you can do so at any time, even after putting through a rating.
Thanks in advance, and good luck
