I have a 1989 FORD F150 XLT lariat 4X4 my problem is hard but maybe simple i replaced my starter truck started came out the next day truck wouldnt start without a jump.thought it was the battery replaced it didnt help took the alternator and tested it altenator was good (internal voltage reg) so i started replacing relays and harnesses checked my fuses,and ended up replacing my altenator anyway also my starting solenoid.so my problem is this my truck will start with a jump and run my voltage reading on my gauge inside the truck is low and not showing any kind of good voltage,and when i shut my truck off i cant start it with out a jump.
i really need help for i use my truck for volunteer work for my church and also work i really need it bad thanx to all who give this a shot
ok this is my previous post im still having the same problem but i
would like to know if in got a altenator with the (+) and negative terminals
would that cause bigger problems or would that solve my problem

 

I would check the battery, is it getting old? Recheck and clean all the terminals for the battery, starter, and alternator, as well as all your grounds. Electrical problems are not easy to track down.

 

Either its the battery or you have some bad cables. Corrosion on Battery terminals and internal cable connections. Also Make sure the Engine ground is clean and tight.

 

badstuff, only start a new thread when you have a new topic. Having multiple threads going on the same topic is hard for people helping you follow your progress.
Thank you, and welcome to the forum.

Check or have each cell of the battery checked you might be amazed, but check all ends to battery connections for rust or corrosion inside of the crimped connector
