go hop into my truck to leave for college, i commute to scranton to my college, and turn the key, one swift loud "click"... son of a bitch battery is dead, went and grabbed my multimeter, battery reads 12.35 volts.... aright, checked my wires and relays, swapped the starting circuit relay, tried to turn over the engine again, "click"... yeep, starter is shot, the aramture in it thrws forward into the flewplante but the starter motor wont rotate, just got back from napa with my $130 premium starter motor with the $50 core charge, getting her towed down to my old diesel shop at my old vo-tech... from high school a high school shop to a college shop.. back to a high school shop... haha o man, im so pissed but im laughing about it, figured i would entertain some people with my crappy morning

 

hmmm hate to say it but 12.35 volts is low for a battery. It needs 12.6 volts to crank the starter. You may want to consider taking your battery to a parts store and having it checked. (Load tested). A Battery with 12.35 volts may seem like everything is ok, but under a load it will probably drop. Just my .02

 

all done, taken care of, new starter in, fires right up, 9 out of 10 its a "flat" spot on the armature in the old starter, i did a bench test however on the old one and it operated fine but most likely i loosened up the aramture while smacking it around against the fram rail, o well, peace of mind, my truck will start for the next 3 years guaranteed or a new starter according to napa, idc, i just want to get to college and go work in my diesel shop... 12.3 volts would not raise any flags, just a weaker crank, your never gonna find a battery with perfect voltage its whole life, if it was reading 11.3 volts then yea, throw the jumper pack onto the battery then give it a shot, but that wasnt the cause, the old starter would just engage but wouldnt crank the engine, weird stuff if you ask me, but hell, in the end, it runs

 

12.3 is low next 2 months it wont start...

 

nah i just happen to like to run the accessory switch to lsiten to my radio while i work, im not worried about it

 

oh no wonder ur fine then
