What's left of Our Progressive EMS Unit
This is whats our EMS unit looks like after our last excursion. The box got fried. Bought it in 2009 and it has worked flawlessly up until a couple of weeks ago. No I don't know what or how, but it s...
Forum Discussion
Back on Page 3 of this discussion I noted there has to be more to this story than we know. Then on Page 7 the OP wrote -
"Like I stated in a previous post, all connections were tight when I removed it. I installed this EMS unit in our previous RV in 2009. It was in there for 4 years (no problems), then I transferred it to our current RV in 2014. So it's been preforming it job the last 3 years, and a total of 7 years. So I surmise my connects were done right. Something happened but probably will never know cuz Progressive Ind. doesn't care."
On Page 10 he finally posted a pic of where he installed this EMS, which sure looks to me like it was inside a sealed cabinet. :E Earlier there was discussion about the wisdom of mounting electronics in a plastic box, as Progressive has done with it's EMS products, but I've never had any overheating issues with either of the EMS units I've owned (one TRC, one Progressive). However, the difference is mine have never been installed inside a closed box (as seems to be the case here) which offers no ability to vent out any warm or hot air created by the EMS. Now that we have a pic of where the OP's EMS was installed this may well be a case where he's created his own problem, this not being a sudden catastrophic failure but more likely a cumulative failure caused by constant overheating over a long period of time. Years operating in a closed environment without venting out hot air, it's not surprising this EMS finally melted. If that's the case re-installing a new one would logically only eventually lead to the same result. To the OP - if you're going to install any type of EMS inside your rig you need to provide some means of ventilation for it - mine is under the sofa, sitting on the street side wheel well where air can freely move around the unit and it's never been anything but slightly warm to the touch.
