Inverter Squeal March 19, 2020, 08:33:11 pm Twice on the trip to CA and back (home tomorrow night), after a day of driving, when I shut off the engine after a day, the inverter under the refrigerator squealed loudly and when I opened the door to exit, the electric step would not extend. Restarting the engine caused the step to work OK. No noise from the inverter when restarting the engine. Thoughts?Chris

My bats are 6.5 yrs old, and since I didn't fill them before I left for Morro Bay, I filled them there and they have never been so empty. Took about ⅓ gal. distilled water. Wonder if they were damaged. Anyway, it's about time for new ones. Thanks, Larry.
