I purchased my 2004 40 ft.Revolution last year and finally got on top to seal a couple of leaks when I found out that the solar panel is missing. The connection plug is in the air conditioning cover where the panel should be mounted. I am looking for a part number for the panel and is there an after market replacement? Also, should there be an indicator light on the intake cover in the motorhome? If that is missing, will the solar panel still charge the batteries? Also, which batteries do the panel charge? I realize this is a lot of questions however I received no books with the motorhome. I have found an owners manual but not much detail in there. Thanks in advance........Help!!!
