recently after a fishing trip my 89 ford ranger 2.3l would not start battery was dead. si u out my boat battery in it and used it to start the truck and i kept the boat battery in it untill i got home. when i got home i pulled the pos. cable off the battery and the truck died so i figured it was the alternator so i replaced the alternator and battery cable ends and the same exact thing happend so i check the volts with a meter and i was getting 14.8 charging volts and 12.2 volts on the battery when not running so it is charging. well i figured it wasent a big problem until now. now my truck is starting to miss fire and run rough like its not timed right but sometimes the truck runs perfectly fine. so i checked the battery connection i got a good connection on my battery but i started to think why will my truck not run on its own power from the alternator and why does it need the battery to run. and how does it charge the battery but wont keep the truck running can someone help me figure outthis problem.
