Checking systems before I leave for a trip tomorrow. Start my Onan Gen 5500, wait for the microwave beep noise to kick in, turn AC Zone 1 on (inside temp 100 degrees, outside 94 degrees), set thermostat at 80 degrees. AC unit starts putting out cold air. Turn Zone 2 on with pretty close temperature conditions and it starts up. Within 20 to 30 seconds both AC units shut down, then Zone 1 will statrt back up. It did this 3 times. So, I ran Zone 2 for about 15 minutes, then turned on Zone 1 and both ran without shutting each other off. I have never had to do this where I could not start 2 AC's on one after another and shutting down. I am thinking there is a load problem with the generator. I hear the generator change frequecies from running a nice solid noise to a sudden decrease, then back to normal with 2 AC's running. Not contantly but enough to get my attention.
I have 74 hrs on the generator, keep up with maintenance, use 87 octane ethanol free with Onan's stabilizer product, and exercise the generator at least 2 hrs a month.
Where I am going has shore power so I will be interested in seeing if I encounter the same cycling problem of shutting down. Not an expert but maybe I have a short somehwere; if not a generator issue. I am having the EC30W Energy Mgt System installed by Cummins when I return and will explain the problem to them. Gen still under warranty. They can put a load on it and check systems.
Any thoughts on this?
