UPDATE: Issue Resolved
I pulled the cabinet panel and first connected an extension cord to the TV plug, bypassing the cutoff module. That didn’t resolve it. Then I started checking all of the connections to the splitter and booster switch. Sure enough, just as a member on a different forum had suggested, I found that one of the coax connections on the booster switch was very loose. Tightened it up and that resolved the issue. I also tightened up all of the other coax connections while I was in there.
I would have never guessed that a poor coax connection would in any way be related to house lights interfering with a cable TV signal. Who knew.
Thanks to all!
FINAL UPDATE - So, what caused the high temperature alarms on our inner drive axle tires…well that remains a mystery.
BUT the process of eliminating the possibilities has been pretty insightful and educational with Frank and Tom’s guidance.
Improper Tire Inflation? Nope, all pressures were acceptable with no cold pressure variances from one morning to the next and no major unacceptable pressure changes after a couple of hours on the road.
Taking the advice of Tom and Frank, today during our drive day, I asked my wife to record tire pressure and temperatures every hour. We did this so we could learn what is “normal” for our tires so that any significant variations in the future, will grab our attention. I’ll be crunching those numbers later to identify our “norm”.
Brakes dragging? Nope. The comprehensive air brake test that Frank and Tom provided, proved that the brakes were not the cause of the excess heat. Confession: I have a less comprehensive air brake test that I printed and laminated and placed in the pocket by the driver’s seat…and there it stayed but for once a year at the beginning of each camping season. If the brakes were dragging, I would not have known it and the potential damage could have been disastrous.
Bad Bearings? Nope. Not likely since the inner tires on both ends of the drive axle dispatched temperature alarms. It would be a real long shot for both sets of bearings to fail at the same time. Following Tom and Frank’s advice I purchased a laser thermometer and checked wheel temperatures during a fuel stop today. All good. Drive and tag temps were right at 125 F and the steers were right at 110 F. The rear end (aka “pumpkin”) was 202 F.
Overloaded drive axle? Nope but not perfect. A visit to the CAT scales showed the following:
Front - 14,100 (15,160 rating)
Drive - 23,140 (23,000 rating)
Tag - 6260 (10,000 rating)
After adding 5 PSI to the tag via the pressure regulator:
Front - 14,200
Drive - 21,860
Tag - 7,380
Still room for a little more tweaking of the tag pressure.
So, while the cause of the alarms is still a mystery it has been a great learning experience courtesy of our forum’s moderators. The depth of their knowledge and their scientific approach to sorting out issues is amazing.
Frank and Tom…thank you for helping me and thank you for all that you do to make this forum so valuable!
