Starting having a problem with SMC, only lifting rear and not reaching proper level. Manual retract would work, but intermittently getting jack warning while driving and applying brake. Application of manual retract switch would quiet the alarm. Parked last night, attempted to operate system this morning, heard one jack seat and then system went dead. Now I have no ignition power or chassis power. Chassis Batteries test good. House jump button lights up the SMC panel, but will not provide enough to start engine. SMC manual shows 15 amp breaker at CB42, and 15 amp ignition breaker at CB24. Can these breakers be reset? Are these located in front electrical box, under drivers area? Or are they like a fuse and need to be replaced if blown. I suspect one of these has tripped. Any suggestions or advice would be greatly appreciated. Thank you.
