No time for working on any of our Rovers either - too busy with a John Deere Gator non runner given to my son-in-law.
After checking out all the electrics and sketching up a wiring diagram for future reference found a dodgy connection at the battery and a fault with one of the rear motors.
All sorted now and it is in the hands of it's new owner our grandaughter. Only problem is she can't yet reach the loud pedal.
A temporary pedal block is in order.
