Electrical Problems

ELECTRICAL PROBLEMS
I have a 2004 Fleetwood Revolution bought used in 2006.
Can anyone help with this problem?
A. When on generator: (7500kw)
1. The Smart EMS, Model 900, indicates 50 amps in, all lights on the right are green and the load meter will indicate the amps being used.

B. When connected to 30 amp shore power:
1. The Smart EMS indicates 50 amps, all lights on the right are green and the load meter does NOT indicate amps being used.
2. The electric water heater, engine pre-heat and the two 115v outlets on each side of the bed do not work.
3. The rear AC works but the front AC does not.

If the EMS is showing 50 amps in when plugged into a 30 amp RV outlet... Then the EMS is defective and needs service.

It works by measuring the voltage between L-1 and L-2, if it's zero, you are on 30 amps (or less) if it's 240 volts (Well over 200) you are on 50 amps.

IT MAY BE (I have not read the owner's manual for yours) that someone hit an override and locked it in 50 amp mose.. You will need to download the manual if you do not have a paper copy and see if that is possible.. It is possible a full reset will fix it.

Try this: Unplug, do not start generator, Activate the battery disconnect and then lift the ground wire off the battery(ies) and then take a brake, say 1 cup of coffee.

The re-attach the ground cable, Re-connect the battery, and plug back in and see what happens.

No guarantee..... but this advice will cost you ... 1 cup of coffee.

The EMS sounds like it's working backwards, perhaps a reset is in order as suggested. Has there been any recent wiring done?

Reset works

I have been having a problem with my EMS. I'm staying at the in-laws plugged into a 20 amp circuit but the EMS would not let me select the 20 amp setting.

Last week I replaced a battery cable and used the disconnect switches. Yesterday I noticed I could now select the 20 amp setting. It must have been reset by last weeks repair! Learn something new every day.

I'm pretty sure you have a defective 50/30 adapter. One side of the 50A shore cord is not getting power, so the EMS sees a non-zero difference between the two legs. That tells it that it is 50A service rather than 30A. But the one side is not getting power (or very much power), so the devices on that leg do not work.

In most 50A Fleetwood coaches, one a/c and the water heater are on one leg, and maybe a few convenience circuits. Most everything else is on the other leg.
