Ok Gang,
Just wondering, since I'm not an RV tech, I'm always learning things here and on other forums. But, from what I've learned in the past, many of the pre-'05, 06 coaches had NO chassis battery charging while the coaches were plugged into shore power or, running off the generator.
Then, after about those time frames, Winney and Itasca both started installing the "Trik-L-Start" system to keep the chassis batteries charged while the coaches were in long term storage. Now, as I understand it, even the Trik-L-Start system is not really a charger but, merely siphons off SOME of the charge for the house batteries and sends it to the chassis batteries to keep them up. And, that system (Trik-L-Start) needs to detect a half a volt difference between the two systems, in order to trigger itself to start sending the chassis batteries some charging.
So, with all that being said, I would like to know if the OPs coach inverter charger is actually wired in such a way that it is tied into ALL OF THE BATTERIES ON THE COACH, no matter how many or, what type are used, in both house and/or chassis??? And if it is, does it, or, is there some form of built in charge controller that, will differentiate between the two sets and therefore, will STOP charging the chassis batteries when they're topped off but, keep on charging the house batteries due to extended use by "Inverting" if and when needed? All this intrigues me.
Again, I'm no expert but, I've never heard of the inverter/chargers being used to charge the chassis batteries. Now, does this mean they are not, nope, not at all. All it means is, I've not ever heard of them charging the chassis batteries. Before it went south, after 10 years of great service, my Dimensions 2000 watt Inverter/Charger was only setup (including wiring instructions) to charge the house batteries. And, when it went south, I installed a Magnatek 2012ME MSW Inverter/Charger and it too, is only to be wired to the house batteries, not the chassis batteries.
So, again, just trying to learn things here.
