Gday all, just got an ED2 Gli 6 cyl wagon with duel fuel and still familiarizing myself with some issues. There's a hose from the thermostat housing to the gas-mixer thingie.Where it connects at the thermostat there had been some sender (which obviously is now not present..and the wire/square-connector's just hanging disconnected)...what was the original sender for and what's affected by it's absence? (it's the rear one of the 2 bigger senders just above the small ?temp-guage sender/switch). I've looked at my Gregorys manual and can only see reference to this small(single wire connector)switch....but no mention of the other 2 bigger senders/switches. Can anyone clue me in on these 3 senders/switches. Note that my temp guage doesn't work either...and I've tried cleaning the single-wire connector on the lower(small) sender...still no joy. Thanks for any advice offered.....Steve.
