“They say” things happen this way but I’ll let you in on a secret…….you’re damn straight! Before I get into this mornings discovery, Sunday morning is usually the time I fire up a pair of wheels and take a 50 mile round trip ride…..it’s not much but it’s enough…for now but hey, the will was there but 40 degrees……. only 50 miles but still……..I waited til it was 50 and took the car…..hey but I did have the windows down…heater blowing hi but I gave it a shot. Guess I can’t go to my “special out of the way spot” later in the day…. this guy was set up..2 fishing rods, smoking his pipe doing his scratchoffs there….guess it’s not as secluded as I thought….. bummer…Ralph and I found another spot to ponder the universe before heading back though Waiting for some warmth though I went in early….yeah I know it’s Sunday…it’s cold but hey….it was warmer in the bighouse so this morning I came in to find a disturbing sight….yes just disturbing….I don’t know if it happened because of the cold but the new quad bag system lost air….shut off! That means the new quad bag system itself…besides the 2 90 degree air fittings I knew of are leaking……this is something else. If it has those “push-lock” fittings on it they’re coming out!
But while I was running the ignition to check the air compressor… none of that was the disturbing sounds….. it was the completely original dash AC blower system! and being an original 1977, it had that “appendix” timer relay still installed This is only on the 1977-78 models…. the complain was the vacuum doors would not open fast enough when the coach was first started……Problem was the pressure of the blower in the box (when you left the blower on hi…hey, we ALWAYS leave it on hi!) held the wimpy vacuum baffles closed until it built up enough vacuum……. Solution? Add a timer relay to keep the blower from blowing until the vacuum system can spool up! And when it goes out your dash blower goes out…… you cannot replace it…no longer produced. If you have this relay still, disconnect the 2 wired connections and plug them together wheich will totally bypass this thing and yank it out! Next…look back 2 pics at the can on the original I’m sure blower relay……..WWII material! All that old stuff has to go if I’m going to replace the blower motor Now for the new Delco blower motor….I try to use Delco on electricals if I can find it So look at how tiny that cute little Delco motor is……. hey but that’s our new parts supply! So, sealing the new blower motor back in, the new blower relay gets new connections pitching the old multiconnectors that fell apart not using the red/white stripe wire (it supplies 12 volts only when the alternator is running) we add a fuse and connect it to the center terminal on the battery isolator….a good heavy gauge wire and a 30 amp fuse in line (the original supply was that wimpy what 14ga. red/white stripe wire? Cap that off! and connect this in place Upgrade the ground to the blower to 8 ga. too…I mean what comes in goes out……. Forget that radio noise filter on the original blower motor I’ve never had noise from the blower motor to the radio…run a straight 8 ga. wire directly to the blower motor and with all that done……here is the new blower motor in the coach will all the stuff it needs to work well
Note the 8 ga. black ground at the bottom of the motor has it’s own short self tapper screw holding it secure to the case of the motor. The other mounting screws go into the fiberglass housing of the assembly. Cut a securing screw to the outside of the baseplate to not scewer the “squirrel cage fan” inside OK, so another issue gets crossed off the list on the window
So that’s what I did on my Sunday morning in the cold Hoping YOU had as much fun as I did! I may post lter tomorrow…it’s ambulance crunch day……see ya on the other side…..
