Question about Cars & Trucks
I dont know how to hook up the batteries the batt. where gone i bought 2 new batt. to put in it and dont know how to hook it up it is a army pickup truck 1986 with a 6.2 deisel
A way to hook up two batteries in a 12 volt system is u hook them up, positive to positive and negative to negative. it will keep it 12 volts. and will give u more watts.
if you hook it up in a series parallel it will become a 24 volt.

SOURCE: 24 volt charging problems .2
A 12 volt battery is actually 13.2 volts fully charged. If you are reading 16 volts, you are probably getting extranious voltage from the system somewhere, especially if the vehicle is running when you check the voltage. The alternator will put out about 15-18 volts to charge the battery normally, and yours may put out 28-32 volts to charge them in series, but the batteries, when disconnected, should never read more than about 13.2 volts each. Typically, it will read about 12 1/2 volts when disconnected. COMPLETELY DISCONNECT BOTH OF THE BATTERIES. If you still read 16 volts when it is disconnected, you must have a bad meter because the battery can't produce that much voltage, no matter what. (Six 2.2 volt cells connected in series inside the case.) Put the meter on a known good battery on another car that is not running and see if you get the same reading. It sounds like the other battery is almost dead, regardless, and it sounds like your series/parallel switch may be malfunctioning. (That is the switch that puts the battery in series to run the 24 volt starter, then puts the batteries in parallel to run the remainder of the vehicle on 12 volts. This is all assuming that you have a diesel vehicle with a 24 volt starter and that is why you have two batteries.

The problem is the voltage regulator is bad. However the regulator is almost as expensive as a rebuilt alternator so unless the alternator as been replaced recently I would suggest to go with the rebuilt alternator.

The alternator on your truck is a self contained unit. The voltage output is controlled by a rectifier bridge and diode trio. If you ground the test point on the back of the alternator (near positive post) it will go full out. Remember if you run at full output constant, you will damage e.c.m., g.e.m., and battery. You will also shorten bulb life and possibly damage radio.

Generally the standard voltage should be 13.5 to 15.5 depending on the load that is being put on the vehicle and age of the battery an older battery may require more voltage to charge. Unless the voltage drops below 13 you are probably ok.
