I recently installed mountaineer seats in my ranger and some other parts from it. I disconnected pos and neg battery cables to connect in my seats. For the last couple days ive been trouble shooting my truck as to why when i turn key on engine off everything turns on as normal, but when i turned engine on half the time it would kill the electrical. Well i went to check my new cables running to pos and neg terminals and Boom. I didnt fully tighten the POS cable and it wiggled loose.
stupid me. guess its better then being the idiot who puts pos to neg... ohh god id just start cutting myself up with a razor blade if i did that. Just figured id post. I mean when a new problem arrives first thing i think, "What Changed recently?". that is the best way to troubleshoot most problems when they arise out of nowhere, or seem to. Its always helped me, in every aspect, from hey my chest hurts, maybe its your new medicine. bam. solved. It almost works in every aspect of life.
