Probably from the early 80s.Timer wouldn't stop, removed all plug in wires from timer area. Found out what I had to do too late! Unfortunately can only remember where to put back 3 of the 6 wires to clock/timer area so oven can work. Can someone figure it out or have the original diagrams??It was a Viking sold by Eaton's in Canada(they've been out of business for at least 20 years).
