So since last update, burb has been to Phoenix and back is now in Ca with me at my Brother's house while I do maintenance to our coach.
Phoenix trip I had front ac issues. The high blower relay failed and I had some melty wires. Stop gap fix I made a jumper. 10 ga wire female spade alligator clip, blower to battery.
Ended up frying the noise filter at the blower with the sparks, over multiple connections.
Not sure if I will replace,. I thought it was aftermarket, but it may be factory. When I got home and repaired the melty wires, the purple blower wire was to short. I had to make a new one to fit w/o noise filter. So front a/c working as designed, 4 fan speeds.
The drive home from Phoenix, I got 10.1 mpg new record. It had been a long day and I was tired so drove very mild.
On the trip to Ca, I left at noon, 104ish out. Had both a/c running.
At cruise volt meter showed just over 13v, at idle well under 13v.
So I gave
@500$k5 a call and ordered the alt
@6872xtc spoke of earlier in this thread. Will be waiting for me when I get home.
Back to the drive to Ca.
Cruising along
@75 on I-40, I am starting to smell something, at first I thought trans oil smoking off exhaust, the it changed to be little electrical, I noticed a slight haz in cab. Oh S%^@. Shut off both ac and roll down window.
Cruise about 20 miles, no smell haz clears away, try the both ac again yup smell back, system off.
Got my pup with me she needs a break, so I stop at Kelbaker Rd, nice spot not to far from i40 away from the road pup can run around unattended, while I inspect the front ac wiring I had just repaired day before. All looked fine, blower motor case was cool and no sign of melt.
Get pup back on the road and only use front ac, volt meter sits at 13.7v, maybe a smidge higher. No haz or smell.
Next day check out rear air, I can see that blower motor case has been very hot, doesn't surprise me, records with truck show early 80s install of aftermarket rear air.
I ordered a new blower motor and 2 fan cage from Rockauto, should arrive today. Now to find the time to replace. I might be looking for a new rear air dash switch, not sure if the hi amp draw as motor failed damaged it.
Don't recall seeing 1 on lmc, even if they do not sure I'd buy it.
I sent LMC an e mail re the front blower motor switch, with pictures. They replied quickly, then said had been forwarded to the engineers, nothing since.
Well time to start doing stuff.
