My model has the top that when in the down position extends over the battery box making it hard to access the batterys to jump, I do have the manual jack on the pump but had to make a handle for it as previous owner didnt supply it when i purchased it, i jacked it manually once and it did work just was alot of pumping, after that i installed on the tongue a quick coupler gray 12volt connector with rubber cover that if i ever need i have a 20 ft set of jumper cables i can quick connect to it,
Ezfreddy -- what is your year and model? Where is the manual jack on the pump??
