1993 Ford E-350 Q&A

1993 Ford E-350 Question: starting problems

what is the recommended voltage to start a 1993 ford e350 ambulance -
Answer 1
Your batteries should have 12.6 volts when fully charged, 2.1 volts per cell X 6 cells = 12.6 volts. Have you had the batteries load tested to make sure they are maintaining the proper voltage while cranking? Too much voltage drop will keep the starter from turning properly; too much current draw from the starter will also cause problems. Are the battery cables tight and in good condition? -
Comment 1
I AGREE, THAT IS FOR EACH BATTERY! WERE BOTH INSTALLED AT THE SAME TIME? DOES ANYONE USE A HYDROMETER ANYMORE? YOU HAVE A TOTAL OF 12 CELLS IN 2 BATTERIES, IF ANY CELL IS DEFECTIVE IT WILL AFFECT ALL OTHERS. JUST LIKE YOUR FLASHLIGHT. -
Answer 2
ideally you should have 12.6 voltes, you should start it with 12.0 voltes as long as it does not drop below 9.5 voltes WHILEST cranking -
