    I need to buy the power cord for the 12 volt jump start model 38391. Can you help me find one. Thank you.

    Instead of writing a comment, I asked a question. Will you be able to reply with your answer? If not, could someone at Harbor Freight be able to help me? I charged up the Unit and for the first time it failed to work properly. I have owned it for about three years and it has been a godsend . Money very well spent.
  • CIRO AENONE Mar 02, 2017 11:45:
    After turning the ON/OFF Switch to the ON Position, there is no charge whatsoever​. With the Switch in the ON Position I then press the Test Button and, again, the needle does not move.
    Does this indicate that the switch is defective? Can I safely disassembl​e it , try to repair or replace it, and then reassemble the Unit>?
