Hi! I have a Freedom 25
Inverter/Charger on my boat and an old 1987 Lippon "go anywhere" microwave. At times, when I use the microwave while plugged in, the amp meter usualy goes up to about 11 amps and stays constant. However, sometimes, the amp meter will go back down to about 1 or 2 for a couple of seconds, go back to 11 for 10 seconds or so, go back to one, and so on. I thought the microwave might be the issue since it is so old and it didn't seem like it was heating
as fast as before. So, I tried this with a new kenmore microwave (that used 1 instead of 12 amps) and it went back and forth as well.
I am wondering if the amps jumping back and forth is normal? I would think that a microwave would keep using the same amount of power while it is running. But I could also see the microwave cutting down the power at times while running. I am kind a little worried some of the wiring
may be having problems. Any thoughts?
