hey guys does anybody know if i could use this rpm gauge on a 1984 mercury 150hp black max https://www.amazon.ca/docooler-Digi...TF8&qid=1470159059&sr=8-6&keywords=tachometer
instructions say to attach to the spark plug. and then ground to the motor. i was thinking of using the merc harness sender wire (grey) and the ground wire instead of spark plug and attached to frame.
. i believe my current rpm gauge fried. i was in the middle of my run i noticed the rp gauge bounce around and then cut. i checked all the connections it was fine. the motor runs perfect and starts easily, so hence why i think the rpm gauge just quit. i want to put something cooler looking than a regular analog gauge.
thanks!
