Links to threads from one of my forums...ditto solutions from another of my Boy Racer forums, but won't link them here
Note that there are some posts with sleezy stuff and part of why that forum died...freebie and out of pocket ran into better software needs...but not enough of the members pitched to help defer our costs

Positive battery terminal modification My first post on this GM battery side post discovery and solution. Year 2000, so my Suburban has 17 years with that modification and have NOT had a connection problem since... Hasn't died for unknown reasons (sure the fuel pump has left me stranded a few times and once with ignition module dying). No more mystery computer resets by itself, etc.
