Batteries new, alternator new, starter new yet STILL will not hold a charge. HELP

 

check fuse 2.45, its a 10 amp fuse. When the alternator fails, it can burn out this fuse for the indicator and prevent the batteries from charging,

 

If it charges when running but loses it overnite you have a parasitic draw. Best way to find is to disconnect batteries, place low volts meter between battery and cable. Don't forget both batts need to be disconnected. If you see volts over zero with everything off you can pull fuses till u see what circuit is problem.
