Thanks for the help so far Robert, Now I have a new problem.
in the diagram where the sequencer is, the saw tooth looking symbols under M4-M3 and M5-M6 is a symbol for internal resistance but is that the connecting tabs at the bottom of the sequencer closest to the mounting plate?, that are unmarked? There are 2 sequencers one has M1-M4 and the other M5-M6. My question is Does the BLACK/WHITE wire going to the 24V side of the transformer and the WHITE wire going to the T-STAT harness go to the sequencer with M1-M4, and the and the Black wire from Blower Relay post 3 and BLUE wire from the T-STAT go to the sequencer with M5-M6?
a friend had replaced the sequencers a while back but there was no diqgram used then and the BLACK/WHITE and WHITE wires were on M5-M6 seq. and BLACK and BLUE were on M1-M4 seq.
My father replaced the BLOWER RELAY and TRANSFORMER a few days ago, and on the Blower Relay he had the wires from post 2 and 5 switched around, the system worked but could not turn the Blower on with ON switch on T-STAT. with it like this I had to put Auto/On switch at T-Stat to ON and Auto/On switch at furnace to Auto for Heater to Work if not the heating element would heat up but blower would not come.
After finding my wiring diagram yesterday I wanted to check and see if I could get the AUTO/ON switches working correctly. I first notice the Sequencer wire from 2nd paragraph and switched then to the way stated in 1st paragraph, but DID NOT notice the switched BLOWER RELAY wires. Turned the breakers on, noticed a flash and turned them off. Then noticed the switched wires on relay and thought they may have caused the flash. I put the Relay wires in correct places according to the Diagram turned breakers on. The AUTO/ON switches work correctly now BUT now when I turn the heat on the elements heat but the blower does not come on even when all wires are switch bakc to the way they were when the furnace worked. Did I blow the sequencers/ I just ordered new sequencers/ both limit switches, relay, and motor capacitor, transformer is new, I am just going to gut the system and replace all parts But i am confused on the sequencer wireing
