May as well be new! I probably used it 2-3 times back in the day. Comes in original box with owners manual. ALWAYS stored carefully in my dry tool chest since I bought it new. This could easily be considered "New Old Stock"! Box says it works on 12 volt systems with. 4, 6, or 8 cylinders of any brand.
Needs to go to a good home with someone who can use it. Cash sale only, please. Thanks for looking.
