Yanmar with aftermarket tach and temp guage
I am tying to connect the following equipment to my Yanmar 2gm (1982), and am looking for advice. Thanks in advance!!:
1. Diesel electrical (Faria) tach. Although my panel doesn't have a tach, i do have the tach sensor, on the engine, and wiring going to the panel (unconnected). Yanmar manual shows 2 wire s(orange and blue/red), form the sensor, connecting to the factory tach, plus power and ground. My new Faria tach only has connectors for power/ batt, ground, and one signal (not 2). Anyone know if I can make this work? I tried each of the 2 sensor wires separetly, but with no luck.
2. Aftermarket temp gauge. I tried splicing into the temp sensor wire, where it connects to the temp alarm lamp, in addition to connecting the guage to power and ground, but with no luck either. Thoughts? Would the sensor signal used for the alarm lamp and buzzer be "graduated" to work with a guage, or would it be a threshold type signal only??
