Hi folks, this is my 1st post here. While installing new 6 volt batteries in my MS I momentarily reversed the cables! As a result I lost power to all four slides, 2 hyd and 2 elect. I have full 12v on all other systems. I replaced the 3 30A fuses at the converter and don't see any others blown. None of the blade fuses in the power control panel are blown. I suspect the 30A relay or the solenoid at the hyd pump. Any ideas? Thanks for the assist.
