2000 super duty
Under hood fuse #22 50 amp junction box battery feed . Parasitic drain. Both batteries disconnected. Meter on 10 amp scale. Meter shows .21 draw.. Remove fuse , meter reads .01 What accessories does battery junction box feed .. Batteries read 12.6 volts but no cranking amps. Specific gravity test shows one cell needs recharging. Have to use NOCO 150 to start engine every time i shut down. Alternator puts out 13 + volts but batteries don't hold charge. Two years old. AAA and Autozone say batteries are OK. Need some help. Thanks.
