Strange EHV actions. This is my first post, although I have read many of the entries over the past 20 years. Right now I have a 1989 300 TE with 288,000K miles and have recently replaced the head gastket, water pump. The car set for 4 months b4 I finished it. The problem is that the car starts/runs perfectly until I connect the plug to the EHV, which immediately causes the motior to stall and the auxsillary radiator fans to start.
I checked the "all seasons temp sensor",, the EHV, neither made a difference. Another strange thing was that the interior light would not go out when the door was closed. ( yes, the light switch was fully forward. This has started working correctly. In fact the cars rins like a sewing machine at all speeds, only occasionally a very minor hunting at idle.
