got a tilt-n-trim unit off a 1987 70hp Evinrude. I would like to test it before installing it on a motor. it is a 2 wire unit (1 blue, 1 green) how can I test it to a battery?
Nope--No need to ground the unit at all.--------Touch blue to positive and green to negative for up.----Then green to positive and blue to negative for down.
