Today a local hunting club called us up to swap out there single dish with a super dish just so they could get the locals for there big derby party tomorrow, so being such a simple project we went over there about 1:30 checked out there set up which was two older Winegard receivers that were fed directly from the dish. The receivers were new enough that they did have superdish listed on the setup menu, so we installed the new dish put the 3-4 switch by the dish. When I landed one of the receiver wires on to the switch I saw a little arc not major thought maybe I brushed the lead against the case. So landed both wires on the switch went to the main TV and nothing the receiver couldn't see the switch so checked voltage coming out of the receiver and had nothing. So I grabbed a new 311 out of the van just to get the dish sighted in to get the other guy off the roof. Did that and it instantly saw the switch got the dish sighted perfectly. Then when Marc came in from the roof he went into the other room to check the other receiver as soon as he powered it up the new 311 started shooting sparks and flames out of the right rear of the receiver where the satellite in is. And now the receiver in the other room comes on but acts just like the first one will not see the switch and puts out no voltage. Has anyone ever had this happen to them or know why it happened? The only thing I can think of is a bad 3-4 switch. I ended up taking my 3-4 switch from my house and one of my receivers throwing it in there and it worked but now will not see the 119 sat but all I needed was the locals so I didn't care at 7:00 pm on a Friday.Any sugestions for Monday?
