Tomorrow I can take a look at the Mefi ground. What is the proper way to test this?
Mefi ground, you can back probe the connector, using a dvom set on ohms, one lead on connecter the other lead on a known good ground, perferably on the main engine ground if good it should read ~.1 ohm if you got nothing or infiniti the ground is open. Or you can just run a jumper wire from engine ground to the mefi ground pin 85, this would ensure a good ground.
