Power seat and refrig wiring
Posted: Mon Sep 23, 2013 4:47 pm
In preparation for adding batteries under the couch and upgrading the converter I was reviewing the existing wiring and verifying it with a 95 owners manual someone was kind enough to post on this forum. The diagram below appears to be consistent with my 93 b190.
Here's an actual picture of what this looks like under the couch
So the power seat and fridge are NOT fused circuits off the converter but are powered directly from the battery connection on the fuse board which is why I assume airstream has added two circuit breakers to this circuit. There are plenty of open fuse positions on the circuit board which makes this circuit seem a little odd since they could have used them to supply power to seat and fridge thus avoiding the circuit breakers and messy wiring.
The only rational for not using the fused circuits that I can think of is if the power seat and fridge each draw more the 20 amps which is the limit on the fuse board. From what I've seen on this forum the fridge draws 10amps. The power seat amp draw is unknown as I can't find any information or posts which contains this information.
As an aside, I think it's kind of strange to power the seats off the house battery and not off the starter battery. I can't think of a reason as to why airstream would do this. Others in this forum have mentioned it before.
So I'd kind of like to clean this up a little by removing the circuit breakers and creating a 15amp circuit for the fridge and a 20amp circuit for the power seat. Here's the diagram showing the modified circuits.
Has anyone done something similar to this? Has anyone determined the amp draw of the power seat and fridge?
I appreciate any information, feedback or thoughts on going in this direction.
Thanks for the help!
Mike
