thanks - Robert
On the cover there should be a list of what the fuses are for and their size. I just looked at mine. It has 11 fuse slots and uses 8 of them. Parallax recommends 15 amp fuses in the 8 slots that are used. This was printed by Parallax on the cover. Mine is the 55 amp model.

If the gas leak detector is powered it activates the propane shutoff valve(solenoid). That could very easily account for the additional current draw. Try turning the detector off. That causes the valve to close and power to the solenoid valve and the control circuit is no longer drawing current.
If you have a powered awning with remote, it too is always consuming some power.

Also check your stereo which is most likely hard wired to the 12v. I'm not sure what you are actually trying to achieve, but unplug the power cable behind the stereo and see if that accomplishes what you desire.

Read this thread forward and then backward. Still don't get it. What's the imperative to have the converter's fan off? It's doing what it was designed to do.

Next look at the specs for your converter, you can usually find it on line. Some fans are temp activated, some are current flow activated and I guess some even just run if there is current draw. Decide if what you are seeing is normal or actually a problem.

I agree with the others Re: the FRIG always draws a small current to the digital controls. Most other things like the CO detector and propane detectors use some, but very little power. IF you are worried, check the draw fuse circuit by circuit.
If the refrig is turned off at its control panel, there should be no current draw.

Removing each 12v fuse one at a time to look for the current draw will not (may not) find the device still drawing current. Manufacturers use inline fuses and circuit breakers for some current drawing devices. You may have that situation - just be aware of that.

For example, when our TT factory battery disconnect is shut off, the front leveling jacks still operate. (Dealers wanted this feature so they could operate the jacks without having to get the keys to open the trailer to enable the battery cutoff switch - to aid in moving the trailer in the storage areas).

Won't the converter itself draw some power?

High ambient temp

If the high temp sets up the operation of the converter fan what would then cause the .1 Amp current through the one circuit. The fan itself doesn't go through the fuse panel it is contained in the MBA of the converter. The temperature recently has dropped to mid 80's and the problem hasn't occurred, only when near 95. The sun shines on the back of the RV and the refrig is on the back wall so I was wondering if there is some circuit in the refrig that is activating the current draw even though the refrig is turned OFF.

I wouldn't think so but guess anything is possible. Sense the unit is 10 years old who knows what a previous owner did. He may have added a fan that is hot (running) all he time. Turn the fridge on. ID the fuse for it. Shut it off and pull the fuse. This will tell you if it is something on the fridge that is not controlled by the on/off switch.


I am still curious as to why you are concerned about this. Also why you disconnected the battery while on shorepower? What am I missing?
