I'm having major cold start issues...anything under 45 degrees and I cant start if I'm not plugged in. I read all the other cold start threads and it seems the problem is more than likely the GPR or the plugs themselves. I'm trying to understand exactly how the relay works so I know if I'm metering it out correctly. I'm assuming that the small terminals are the connections for the coil and when energized the large terminals should close. There is always 12VDC at the large terminal with the orange wire so I guess my question is, when the relay is energized I should have 12V between the large terminal with the brown wire and the negative terminal on the battery, correct?
