just a comment.
these digital gauges we are talking about here are cyberdyne. that is what newell used for years. i have observed several strange things about the digital temp gauges which leads me to believe that perhaps the reading of 225 and or when i had 212 was NOT (edited) accurate. hear me out.
lets start with my digital temp gauge for the genny water/coolant temp. when the genny is running and is at a steady temp reading (without the main coach engine running), all is good. as soon as i turn on the coach ignition switch and start the engine, the temp immediately increases about 10-20 degrees. like you can watch it go up from say 190 to 210 in 20 seconds. if you turn the engine off, it settles back down as fast. i had other issues with the temp readings at first so i have actually changed the gauge and the sender on the genny thermostat housing.(gauge still did the same for going up when ignition was on) now the temp is accurate UNTIL you start the coach engine. so i have learned to kinda subtract 10-20 degrees from the genny temp when driving. but, not all the time. i know, check the grounds etc. but easier said then done to get a new ground to that location. the main thing from this is that the temp on the genny coolant does not go up by 10-20 degrees in less than a minute just because the series 60 is now running.
next...
when i did the check on the aquahot, if you recall i said something similar. it was a slow steady increase on the temp of the aquahot boiler water. climbed from 98 to 198 or so and then you could hear the flame for the boiler shut off. the gauge climbed another couple of degrees slowly as you might expect. then the motor shut off completely after a minute or two and then the gauge climbed another 10 degrees very quickly like i described the gauge for my genny did when the ignition is turned on. no way after a slow steady increase with the webasto firing that now with it off, it increased 10 degress in less than a minute.
i believe on mine, the gauge is not accurate and that the top temp is actually around 200 degrees and everything shown after the webasto shuts off and is still off is a guage problem and not a aquahot problem.
it almost sounds like chesters is the same. how could the aquahot go from 200 degrees when chester says his shut off to 225 with the burner off?
i will try it again today when i am doing some things out in the garage.
if what i am saying is right, then we dont want chester trying to fix an aquahot problem when there isnt one.
but....could be this is just my coach acting this way.
food for thought.
