Is it a battery and what I think is for?

Does the RV have an Gen Autostart if the main/house battery gets weak? Could this battery be just to start the gen when main won’t do?

@wildtoad No, it does not. It’s manual start (rocker switch Prime/Start/stop). Whether this battery could be the backup for the main I have no idea. I know for a fact that the generator can still start when the coach battery is disconnected (switched to off). So, maybe it is the backup battery kicking in, but I doubt it very much that my unit is at this level of sophistication.

@dodge_guy mentioned that he never heard of a dedicated battery to start the gen. Actually I don’t know it for sure either, it’s only my guess. I had conjectured that the generator draws its power off of the truck battery, that is, until the discovery of this mysterious battery.

Both Tom_M and bobndot suggested that I disconnect the battery and figure it out. While that would be straightforward enough, it may not be the easiest. As I mentioned in the OP, the battery terminals are not easily accessed and harder to work on when you lay flat on the creeper. Tracing the electrical cable run from the positive terminal is also daunting, if not impossible, as it is braided with other cables into a larger bundle that runs alongside the chassis. I was hoping for an easier way out – by asking. To that end, though, I was surprised by the seemingly lack of industry standards in this regard. It looks to me that all RV manufacturers do not use the same/standard practices in dealing with the power systems (hence us consumers’ understanding/perception of it is all over the place). I just hope my generator does not die on me before I got a definitive answer…

Speaking of calling Coachmen for technical support, I’ve tried this route in a couple of (other) occasions before without any luck, in fact they never bother calling me back or replying my emails. I can try my luck again I suppose.

Thanks for all your replies.
