Always check the fluid level in each of the battery cells and top up with distilled water as required.

Using a multimeter you can assess th health of your car battery and alternator:

  • With the engine off, measure the volatge at thebattery terminal: it should show 12.5+ volts, anything under or around 10.5 volts indicates a shorted damaged battery cell -> bad battery!
  • With the engine running, the voltage reading at the battery terminal should indicate around 13.8 volts and anything under 13.5 volts and over 14.5 volts indicates a bad alternator and/or alternator regulator.
Hope it helps!

My alternator is not charging the battery checked alternator its OK. Checked wires to alternator OK what could it be


Not sure how you checked the alternator to say that it's OK, but if it's not charging the battery then it's not OK. You can take it to most auto parts stores and have it checked along with the battery to see which one is bad.

I've been having a problem with my 2000


No.dont diconnect the negative or positive battery at all The alternator only produces 2 volts above battery voltage so a total of 14 volts. If you dont have a volt meter get a small screw driver be careful doing this if you can safely access the back of the alternator (without shorting anything out)in the midddle of the alternator will be magnetic. That will tell you its charging or better yet get a compass and put it at the battery positive terminal and it will swing that tell you its charging. You disconnect the negative the whole car shuts off you disconnect the positive the car stay running but produces high voltage and can damage the alternator itself

1992ford ranger -alternator dont charge battery


If there is power to the big wire that is bolted on to the back of the alternator and no power out of the small wires that plug in to the alternator then it is possible you need to replace your alternator. start the vehicle and check to see if there is 14 volts at the battery while the vehicle is running if there is then the alternator is good if not replace your alternator and charge your battery with a charger to make sure you have a proper charge on the battery.

Not charging after new alternator and battery my 94 mazda protege has beeen through 3 alternators in 2 months and the battery and alternator are brand new, less than a week or two old and still not...


check for a big heavy fuse nearf the battery,i dont know if it has one?? iam a general mechanic not a mazada specialist,try this trick ? start engine and hold rpm at 1500,then disconnect battery and see if engine stops if it carries on running then altenator is working.If it carries on running then turn on all electrical thingys except the radio.If its still running ok then fault is elsewhere like a discharge overnight.
