pop starting only, batt has 12.5 amps - dynabill - 05-17-2014
Hi all my son is having trouble key starting his car. It will pop start and run but wont start with jumper cables. if you try to crank it, it sounds like battery is dead. Battery has 12.5 volts(this may be low?). New battery and new alternater in the last six months. this leads me to thinking the cellinoid on starter is bad. I guess I am just looking for confirmation. I will let you know if there are any other symptons. Thanks for your help cheers Bill

12.5v is about 25% low, the question is, why is it low?( my wild guess, excess cranking?)
what is voltage running? 13.3 to 15v across the batter is correct. if alternator is working and engine 750 RPM and more. (belt not loose to ALT)
but the jumper cable failure is key.
slow cranking, (sounds like dead) what does the sound , sound like.
1: starter dead silient.
2: starter slow.
3: starter clicks.
for the starter to click , (at least) it only takes, (besides charged battery, good key switch and good clutch switch.
firsts is to wiggle key, and wiggle clutch pedal depressed, cranking.
then smack the starter then solenoid with a hammer. no so hard as to cause dents, taps.
last , hot wire the starter solenoid, jumper the big lug to the tiny lug.
it must crank now. or battery /starter or cables are bad. (by bad battery, that can be discharged) all 4 ends of the starter cables must be clean and tight.

hey jerry, thanks for stopping by, seems like it was just a loose belt (so far) i was on my way out as he was on his way in so i fired off a smoke signal, to get ahead of the game. i didnt try and jump start it, so that was heresay, haha. At any rate, it seems to be starting and running as well as ever,thanks to your help. sorry about the dry run on this thread. but I think it can be closed for now. Cheers Bill
