you really should read the manual again
but go download the pdf book on your slides maker, its not thor, its either lippert or bal
as a rule running more than one at a time probably pulled a tons of amps
is your 12 system still working?
did the big fuses at the coach batteries blow or fail
i would call thor again and who ever makes your slide
bal and lippert despite their faults, generally have pretty good customer help
if its a bal slide...there is also a thermal switch at the motor behind the fascia above the slide
really need more info
hope you get it worked out as they are all closed now till monday
