O.K. Brian ;
The W-123 relays are on PDF file page 52 , that's very nice . I wish they hadn't left California .
So to - day after work I got busy and re installed my Uro brand HVAC fan and tried to cobble up a cigar lighter power plug for it (going to HOTazona Friday) but the test lead I have that fits the fan's plug in , was too short so back to the drawing board....
I was futzing with it and turned the ignition on and punched the control buttons a few times whilst testing the MonoValve , it slowly came to life and began blowing air out the dash vents .
I took the MonoValve apart to try another , used original one , discovered it wasn't leaking , cleaned up the good used original one and inverted the coil , assembled it and connected the wires , set it on the cowl so I could see it through the windshield and played with the temp. wheel , ignition on ~ Max. cold make the spindle jump out 13MM or so , rolling it back to Max. heat makes it retract the same amount .
This looked promising , I am told it works as a ' frequency valve ' and as you're driving along it's in almost constant motion , all i cared about was some cool air as I blister my way across the Desert so I buttoned it all back up , cleaning everything as I went along (Example: there was a blob of some gooey reddish stuff in the tiny screen,I used a new toothbrush and aerosol brake cleaner to clean it off , the screen is still reddish and not easy to look through , I may experiment later with swapping the new rubber and screen from the inoperative no brand ' kiss me quick ' spindle , if that works I'm all set for life) .
A while back I discovered my overboost protection valve wasn't open so I by passed it and that's been bugging me ever since so as long as i had my hands grubby I removed the intake to ALDA pipe , it was broken into several pieces and patched up with rubber hose here and there , another thing I didn't like looking at so last Sunday I bought an unbroken one from a badly wrecked '83 300D sedan , got the pipe and the valve too for $5 , it was also clogged , both the valve and the plastic pipe with banjo fitting on one end so I found 4' of thin fairly stiff wire and as always , my faithful aerosol can of brake cleaner , blew it out a bit and noticed the inside of the banjo ring fitting was full of black crud , took a war surplus dental pick and scraped it out , forced the wire through the pipe a few times until I could get it in either end (kinda tricky getting it in the banjo end) , each time I got it in I'd work it back and forth a while then withdraw it , wipe the accumulated crud off the stiff wire and blast the pipe with brake cleaner again.... slow and somewhat tedious work but in the end , knowing a thing is done right is it's own reward .
I buttoned it back up and took a test drive , the overboost valve closed up again so I by passed it in a Chevron Station and it runs fine again .
As the fuel gauge is below 1/4 tank , I took the opportunity to remove and clean out the clear plastic fuel intake screen ~ I'm about to run it out of fuel again and am not getting as much black crud in there as I used to .
here was of course , a whole lot more I did but i'm done for the night .
It's nearly 11PM , I'll get back to it to - morrow .
-Nate
