Remote Entry/Cargo Lock Problem

[RickO]

Having trouble with the SCS/Frigette keyless remote entry system on my 07 Itasca Ellipse 40FD. Following heavy rain here in Ca last month, the keyless system quit working entirely. The dealer found a faulty control unit and replaced it under extended wty. Then, I drove 500 miles mostly in the rain and now the entry door and patio side cargo bays still work with the remote but not the road side bay doors.

Nasty road conditions had gotten all of the bay locks dirty and I could even hear the grit inside when I used the key. I cleaned the locks out as well as I could with silicone spray lube and removed the lock mechanism covers from the inside of the bay doors. There doesn't appear to be contamination inside the lock and I can see the solenoids attempting to engage when the remote is pushed... there's just not enough "umph" to actually engage the lock. After the cleaning, several of the doors will now lock with the remote but not unlock. I should add that the buttons inside the coach used to lock the doors have the same effect as the wireless remotes.

Should I be looking for a ground wire whose connection got dirty in the rain and is creating a high resistance and voltage drop to that side of the coach?

Does anyone know where the control unit is located on this coach?

Any insight will, as always, be greatly appreciated.

One trick that we Monaco folks learned while searching for the remote control box is to turn lights off in coach at night and lock it ... then look under dash for a flashing red light.
It may not be the same for you... but it is worth a try.

I would suspect either a bad ground or more likely a bad connection at the controller that will be under the dash. If you cannot find the wiring problem you can either contact Winnebago for a wiring diagram or just run a new wire from controller output to the first compartment lock and tap into the circuit feeder, the rest should be tied to the circuit already.

Thanks for the quick replies. I'll check under the dash and also measuer the voltage I'm getting at the bay door solenoids and see where the mystery leads me.

RickO, sounds like you're on the correct path by checking the voltage at the relays in the DC distribution panel. You stated nasty road conditions caused your locks to get dirty while driving. I believe the electronic remote control locks are somewhat mechanically isolated from the key locks. Dirt in the key tumblers needs to be cleaned, however, this should not affect the electronic locks. Sounds like a poor ground or poor power connection.
