okay so about two weeks ago I had an optima yellow top and a 5 farad cap along with an epicenter in my trunk... got a stinger spg32 isolator everything was working great turned off the car at 14 volts and turned it on to have 16.3 volts when bumping around 13... then the other day my water pump pulley snapped I was a across the street from a shop so I left it there to get switched... when I pick up the car it takes a little cranking to start though it was because it sat for a day and a half then I drive to work and the fan wasnt working no big fixed that but it wont blow hard and its getting the feed on a relay from the stinger isolator... then I check my voltage and its at 12.2 out back at idle. I rev it and it goes down. but all my light work fine... buy a new relay for my fan same thing... checked all my wires front battery has got 14 volts but the back stuff just keeps dying? did my isolator die from not having current for like 1 minute?
