ok so i have a 1993 dodge d250 2x4..ok i went to start my truck and nothing happen so i was like what the heck..lol checked the battery cables and post all good jump started the truck cranked drove a from house to friends shut off went to leave same thing won't start so i changed the battery and put a batt that come to fined out was lower on charge then the first one that was in the truck..cranked up went to my work (autozone) checked the battery that was in it fully charged i was like kinda weird so i checked the alternator pushing 60.5amps i knew that wasnt right..but my question is if my alternator was going bad why would the battery i took out still be fully charged? having a bad alternator would have drained the bat a little bit. also if the alternator was bad how come when i put the second batt in my truck cranked right up like everything was fine..please help can't drive my truck till i get it fixed

 

did you check for both voltage and amperage or just one or the other?

 

Let me get this straight. One of the batteries that would not start the truck was fully charged. Is this correct? If this is so the problem is in the starting system not the charging system. Did you test the battery under a load? If not the test is not valid. Something is probably loose or dirty.

If this assumption is wrong please clarify for me so that I can help you.

 

it sound like your starter could be dieing. when a starter starts dieing it requires more power to turn over.

 

Since lets baja said nothing happened (IE: no clicking) I would think the starter motor is OK but the solenoid on it may be a problem.

 

dodge can be funny that way. my old 3.9 would never click even when the battery voltage was good or bad. it would either turn over or it wouldn't. you could take the starter in to be tested.

 

Hi,

I would also do a voltage drop test on the starting system to rule out any excessive resistance in the starting system wiring

 

sorry guys for not getting back sooner...yes i did test it under a load and yes a fully charged battery would not crank it..it weird because none of the lights were coming on like it was the batt and when i jumped it, it would crank right up which also lead me to it being the batt..come to find out it was the terminals the most easiest thing to check and i guess i didnt clean them good enough..but everything is workign great now jsut gotta fix my torq converter and tranny..thanks for all your guys help ..have a nice holiday
