Trying to locate Intellitec EMU-2 in coach

Sorry to keep returning to the forum with the same problem, but I'm very grateful for all of the advice that we've gotten so far.

At this point, our shop seems disinterested in helping us get cool by our departure deadline (8/10) and no other local RV shops can get us in before we leave. And getting someone to offer advice based on someone else's diagnosis...well, I understand that mechanics are reluctant to do this.

We would like to replace the EMU-2 with a simple toggle switch, if possible. This will prevent both rooftop AC units from running at the same time just as effectively as the EMU-2. Failing that, I can hardwire one AC to the thermostat and we'll just do without the other while we're workamping the next six months.

The hard part? Finding the EMU-2 itself. I cannot physically find it! Yes, this makes me feel like a damnfool, but it's not in the fuse/breaker panel under the refrigerator (nor behind it), it's not in the wall behind the thermostat, and I am unable to find it in any of the exterior access panels either. Can anyone who's had a mid '90s Dolphin or Sea Breeze help me out?

I don't have this type of coach, but can try to help anyway.

Here's a link to the EMU-2 service manual. It shows that it has a current sensor connected around one of the shore power wires. I'd start looking around your main breaker box for this sensor. It'll be on the 10AWG wire connected to the incoming 30A breaker (or the 10AWG neutral wire paired with it). Hopefully you will be able to trace the small sense wires back to the actual unit.

A second place to look is around your transfer switch, usually located very near to where the shore cord goes into the coach.

Good Luck!
Stewart

Are you sure someone didn't do a modification to run both A/C's at the same time... It's a common mod on 30 amp RV's... Look in your generator bay and see if you have a 120V plug on a box on the wall... unplug the plug and rear air will stop working.

There is such a box in the generator bay. Is there a chance that unplugging it will make the EMU-2 start working again? (Presumably the modification was made before we purchased the coach in 2008, and the AC units and EMU-2 were working fine until the end of June.)

I have the ECC-2 and it is tied into the thermostat. The ECC-2 black box is mounted behind the wall where the thermostat is and is accessible by removing a panel in a cabinet in the bathroom.

The electrical box with the plug by the generator - when the plug is in, the generator will power the second AC. When un-plugged, you can then plug in a second shore cord into the outlet getting 50 amps to the coach from both cords which should fool the EMU to think you are on generator. Do the A/C's work on the generator?

Both A/C units work when the generator is running, should we choose to turn them on. Neither works on shore power. Unfortunately, where we're going, it will not be feasible (or economical!) to run the gennie all day to keep the A/C going.

You should be able to unplug this plug, connect it (through adapters as necessary) to a 20A outlet (located along with the 30A on most CG pedestals) and fool your EMU-2 just like it is being fooled when you run the generator.

You may have to buy a 30A extension cord but that will be cheaper than finding a new EMU-2. You can use a smaller extension cord but make sure it is 12AWG wire to handle the A/C current.
