Any update?
Jim,
this actually makes sense to me because the temperature sensor/sender for your unit is immediately BEFORE the solution outlet.
This of course would make it AFTER all pressure and temp bypass measures.
I guess one way to check is to hook the temp gauge to the sensor at the hx which normally serves as a shutdown............
anyway....I'm still not sure what increasing the PSI may do other than increase the amount bypassed resulting in less heat transfer to what amounts to a dead end road at the sensor point......
I think so...
day before yesterday I took it out for the 5 cleanings....it still was working backwards to me but I was getting good heat and it was cleaning "normal"...( not normal for me but normal ).....
but..
Every job the EM light would come on and it would shut down....
I checked everything...fan....circulation...everything I could think of......everything seemed fine...I fought it all day long...
brought it home and checked everything again....everything seemed fine....
Called the guy that works part time for me and asked him to work yesterday....4 jobs...I want to take both trucks to each job in case the thermalwave breaks down...
He can do the cleanings and I am going to stand there and baby sit the machine and watch everything it does.......
Long story short....I am standing there listening to the machine and watching everything it is doing...half way threw a pretty good size job.....it started to sound different....pulled the top cover off...and noticed the radiator fan had slowed way down..then it picked back up to full speed...then it just stopped....then it picked up and ran really slow....then took off........OK..that explained EM light and the shut down......
On the way home I stopped and got another fan...put it on last night...when I pulled the old one I broke it apart to see what was wrong with it..............( got to know the hows and whys )....from what I could see when the radiator hose let go and threw antifreeze every where it got in the fan motor and shorted the windings and was making it cut in and out...there was still anti freeze in there......but every time I check it it was fine...so probably when it got really hot was when it started to act up.....but I was always in a house cleaning...........so that problem is solved......
as for the new normal...the machine is working fine...but it is backwards from what I am use to...in other words..from what I can see...both of us are correct.......
that little blue line that is coming off of that "T"....goes straight to my manifold where the solution lines hook up......and from what I am understanding..it whole purpose is for my temp gauge.....it by-passes back for the temp sensor..........there is a little hidden orifice in there that is worn out and is by-passing way to much water....
according to the guy who looked at it from interlink.....he has never seen one hooked up like that before...he does not even show it in his service manual or have a part number for it.....so because this thing is shot it is making it work normal for what he is used to seeing and abnormal for what I am use to seeing........
I wanted to take the computer out of the engine compartment and get it away from all that heat...I was told that you could buy a longer cable to do this.....but from what I understand it is only for the Nissan engines...not the GM ones......while I was replacing the fan last night...I noticed that there is already about 4 foot of cable twisted up and wire tied in there....so while I had it all apart...I made a stand and pulled the computer and mounted behind the filter box..away from the heat and water.......there is nothing wrong with it but...when all hell broke loose and antifreeze went every where........the computer got flooded........and after the fan problem...I don't want to take that chance again...you only get lucky once...........
so it appears I had a chain of events all at once....
radiator hose.....
thermostat...
coolant pump..
orifice...
fan.....
but for what it is worth...I learned a lot more about the machine.....electrical...flow...heat...and a whole lot of new cuss words...............
