Simple idea but when not getting the right result, we may have to go low ball?
Techs can get too involved at times, so just a different idea?
A broken connection can do the same as a blown fuse! When checking for power, did they actually have the info on where power should show up at the controller and check for both battery and ground to let it work?
I hate to think it but I do not have a high level of confidence in techs we find working on RV!
It seems they skip over testing and go straight to changing parts. In this case, changing the parking brake switch seems to be an example. The test on a simple switch that is either open or closed is to just put a meter on the connections at the controller and see if the switch opens and closes the connection!
But the users out here are a bit more handicapped than the techs should be. as we don't have access to the info they should have on hand, nor the back up to call folks with that info!
So we have to dig harder as you really are more interested in getting it fixed! They can just go home at night and forget the whole question!
But that is just where we are, so moving on?
I find we get different info that sometimes leads to questions if we look at different RV with what seems the same problem???
This is a recent example:
issue the switch for the bed slide broke at the face plate how does the switch come off of the contacts ? And where do I find a new one to replace also their is a control box someplace? Seemed like we lost power to the switch with engine on so I tried to remove it and broke the face off even...

We get different drawing info, so is it a different slide system or why does this RV have six breaker feeding two slides, if you only have two power feeds feeding two slides?
Can you tell from looking at this drawing of the slide controller, whether it is the same as you have or different? Age, brand, model of RV and parts can all make a big difference, so I fall back to the basics when starting!
Like any form of mechanical brain, the controller has to both get the right info as well as put out the right info! The old , garbage in/ garbage out idea?
Are we dealing with the rear slide? That can cut the chase in half!
If the same system, why not six power feeds instead of the two we are finding?
A big example of us needing the full schematic drawings info the techs should be able to access!
What we really need is the info that tells us each point on the controller, what shows up there and when! Do you have any brand/model number of the slide controllers? It is worthwhile to check online to see what we might dig up for info.
