Perkins 4-107 Temp and Pressure Sending Units - Testing
How do I test the sending units for temperature and oil pressure? I gave the manuals a once over and do not see the procedure.
If it is a drawn out process, maybe someone could point me in the right direction. I am guessing it could be done with a multimeter checking resistance values, but I don't know how to do it.
Basically, I want to test my alarm system. I would like to be able to put it into alarm manually, from both the water temp, and the oil pressure.
