Thanks for the suggestions John and Kev. I tried to retract the slide this morning and the same flashing red light indicating low voltage. Went behind the module and pressed the reset button, turned the coach battery off, 50 secs later back on, started the engine and big mistake I pressed both the in and out buttons simultaneously which was supposed to operate the individual motors on the slide but it only operated the front one and before I knew it the front was in about 5 inches and the back stayed put! Out came the ? in drive and under I go. After about an hour of sliding forth and back between the motors I finally manually cranked the slide in! Drove to quartzite and decided to try it again (bear for punishment) and lo and behold out it went no problem. Here I sit almost fearful to retract it.
Next morning in it came, and off to BLM at Imperial Dam. Out it went! I don't know if these are things sent to try us. I am going to inspect the wiring for loose/corroded connections once the bruise and abrasions from the previous episode have partially healed.
I have emailed PowerGear with an account of my difficulties but as of yet no response. I have not tested for voltage behind the module as this was part of my request to PowerGear (Where is the voltage tested?). I also tried to phone Winnebago but I don't have enough minutes on my phone to stay on hold that long.
