Last week we got our first blast of Arctic cold here in Southern Colorado. My son and I leave for work early (0530) so our cars occupy the garage and when I leave I pull my wife's '87 740 in. My 240 when it's below freezing never fails to start. When I turn the key on, there's always a few seconds delay (longer the colder) before the dash lights come on with the click of a hidden relay. Last Wednesday, the warmer of the cold mornings (-4) her 740 dash lights wouldn't come on until almost 30 seconds. The next morning, -13, I waited until I had to leave, about 2-3 minutes, the relay would not energize. There was plenty juice to crank the engine, the seatbelt light came on, but no electrical from the relay to the ignition/injection system. Her 740's always been garaged so this is our first experience since buying it 4 yr ago with below zero starting. She went out midmorning when it was sitting in the sun at about 0+ and it started fine, the relay kicked right in. I'm assuming it's the one of the relays on the fuse block, "H", I think from the Hanes manual diagram. Had tried bopping the side of the dash next to the fuses but no result. Called the dealer in Colo Spgs and they said they hadn't heard of cold-lazy relays. Only ignition switches that needed replaced. Anyone have any experiences with this type of cold-start behavior? Seems that contacts in the ignition switches shouldn't cause that much of a voltage drop. Suggestions? Thanks.
