Re: Alternator Output
You need to isolate the problem to the battery or a drain on the system.
A. To check the battery for bad cells, have it load tested at AutoZone with a resistive load. You can also pry off the inspection caps and measure the voltage of each cell with your voltmeter. The cell that reads a lot lower is the problem area. B. To check for loads that drain the battery while parked, try removing the fuses from the fuse block. See if the problem goes away. IF it does you need to figure out which circuit is "stuck on" Look at the brake lights, glove box light, etc. To see if the alternator is at fault, you will need to disconnect the wires while parked and see it the battery stays charged with your voltmeter. Good luck.

Re: Alternator Output
Hi,
What is the alternator capacity? What is the voltage with engine shut off? Usually when charging system is acting up, radio in AM mode will show lots of whiny noise regarless of tuning dial position.

Autozone load tested the battery I bought 3 months ago. A possible weak cell

Re: Alternator Output
MHolland.
Here is a suggestion on how to check for elect. system drain on battery. Simply disconnect the Neg. battery cable end and connect a test lamp between the two. Touch the post and cable end together while the test lamp is attached form one minute to reset the computer. Now move them apart and check to see if the lamp illuminates, if so begin disconnecting fuses till the light goes off. You will then know which circuit is causing you battery drain. If the lamp doesn't illuminate you have no electrical system draw, and it sound like the battery has a problem. Also charge battery and let sit over night disconnected from car. If it is weak or dead the next day you have an internal drain in the battery.
