Hi it is either a bad battery or something is draining the battery if u own a amp meter or can get a hold of one dissconnect the positive
[+] of battery and place one side of gauge on the battery lead and the other side on the [+] battery make sure ignition is off and no lights are on close doors and boot.if the gauge reads 0 replace battery
if it dosnt Then what u need to do is pull one fuse out at a time and check reading. It will drop to 0 when u find the right one. When u have found which one is draining power check what the fuse is for and thats your problem

My can wont charge my battery and it wont rev about 2500 rpm in any gear. i have replaced cam sensor and crack sensor and put new timing belt and tensioner on?


My car won't charge my battery ? Check the alternator (charging system) . You put new cam & crank sensor an timing belt on for a charging system problem ? Or after you did this stuff ,now the charging system isn't charging the battery ?

What color is the light suppose to be when my pyle pro pwma600 pa speaker is charging suppose to be green or red?


Hi,normaly the green light says that the battery is fully charged,so if its red it might be that its charging but not fully charged,but saying that if it dose not charge after some time then the red light can mean its not charging,just food for thought,all the best.

Chrysler battery charge light on


check the charging system and battery to make sure these are working properly. if the charging system is not working then the alternator will have to be check and possibly the PCM as the PCM controls charging voltage and the alternator continuously tries to run a max. check for a code in the PCM related to charging. this may help finding the problem.

What causes the charging system go from charging then stops then charges again


To test a battery use a load tester. The problem may be a cell bridge failure . Check for tight clean terminals and tight wires on the alternator.

Bmw 750il 1999 not start when I changed battery


Did you mean charged or changed? If charged, it could be battery has lost depth of charge. You can charge a "tired" battery for hours only to have "surface charge". Just doesn't charge deep into the plates like it used to. If changed - did you get a big enough battery? That 750 (12 cyl) is a monster on battery and your electrical system is almost in the NASA sphere of complications.

92 yj gauge show not charging disconnect battery engine dies but check with meter shows charging if you disconnect the battery should it keep running if its charging.


It is NOT good to disconnect the battery with the engine running as you could destroy the computer!!

Charge volts with digital multi meter shouild be 13.8v-14.4v...if low then battery must be fully charged to check charge rate.

Meter Explanation


You are correct on all accounts. A high number means you dying battery is sucking more juice from the Schumacker. A low number means the battery is not as thirsty. That's how I always think of how to read the meter on mine. Slow charge is a better, deeper charge. The quick charge will get you going, but you should maybe follow it up using the normal mode - car alternator and prolonged drive time. I never use quick charge, personally.
