So I have a question I am sure i know the answer BUT . I bought a 24 volt power max from a guy , I wired it up in series ( just like my troller) When i go to make my connection( positive terminal is connected) on the ground side of the power max it ARCS bad you could weld with it .I first plugged it in and tested for voltage, There was none, Owner told me they will not read without being connected to battery. So then i tried the above. Removed the fuses and wired it up , Inserted one fuse ( barely) and it arced. Gave up and typed this. What yall think? Im thinking its cooked .Thanks for the help Jerry . P.S. fan never ran either.
