Intellitec Load Shedding problem

Thought I'd post my recent experience with what I thought was a malfunctioning Intellitec climate control unit or flaky generator. I found that when I tried to run my A/Cs on the generator, the Intellitec kept 'shedding' one of the A/Cs. All was well on 'shore power'. What I eventually discovered was that my house batteries were about done and they were causing enough of a draw through the charger that it would cause the Intellitec to shed an A/C. Why this didn't happen on shore power is still a mystery to me since as I understand the wiring, the Intellitec senses the same current flow on either supply. It took a while before I realized that 'hidden' current draw was there. If you have a problem like that, check your house batteries! I have a 2004 Fleetwood Flair with an Onan Gold 5500.

The Intellitec "KNOWS" that when on APU, that you do not have full amp current as with shore power. If you have the instructions, it will show you how the Intellitec is told what amp draw to pull and then shed with a APU(you program what amp APU you have). But, it senses the same amp draw, but does NOT allow the same parameters on APU. I assume you have a 50 amp RV. 50 amp RV is a total of 100 amps, while your 5500 has about 48 to 50 total amp produced(available). Doug
