I bought a used Quad 5100i on CL, it's installed and ready to go except when I picked it up the lower grill with the blower connections was disconnected.....I've got he manual I downloaded off the Quad web site but must be an airhead 'cause after reading the section about the wiring harness I still don't undersand how everything should connnect and my best guess results in nothing happening. On the left of the grill there is a rherostat with a white female and a black male wire, there is also an on/off switch with two male connectors. On both the left and right side of the grill there are a blue male and a red male connectors....those are for the power cord, so it can be located eiher on the left or the right sides. So coming off the right side of the harness are four connectors: Red female labeled "bypass switch" Blue female labeled "bypass switch" Red female labeled "speed control" Blue male labeled "speed control" So I connected the two "bypass swicths" to the on/off switch and the two "speed conrol" ones to the rherostat....nothing else makes sense to me but nothing works.......could the on/off switch or the rherostat be burned out? Could the "snap disc" listed in the manual be burned out, would that cause this? Any help or insight would be appreciated.
