Hi ' If you changed the battery and alternator,
Check the voltage at the red wire on the alternator. if there a less than 12 volt.
Check the fuse link, that goes in the starter positive bolt.
If the fuse is bad replace and recheck the charging system.
IF charging normal. good.
If not, che the fuse in the fuse box, "" cluster".
If the fuse is blow out, replace. and check again.

OK. I hope this work for you.

Intermittent Charging Problem. I posted a question a couple of days ago about an intermittent charging problem. The volt meter will drop down to 12 volts +- and the battery light will come on and remain...


When you wire it in, run a hot wire directly from the battery to the volt meter (this will give you a more accurate reading) The instructions will come with the volt meter on how to wire it. Just make sure about the hot wire coming directly from the battery.

What I would do first is take off the alternator and go to a parts store and have them test it for free. This will save any additional purchases. Good Luck.

Battery voltage is way above 14 volts in my 2000 Chevy Astro Van. What would be the cause of this? Please help?


Voltage regulator module inside the alternator may be shot. It is replaceable. Do that before you go for a complete rebuilt alternator.

On a 2000 expedition multi meter on battery while vehicle is running reads 7.5 car is dying little by little battery draining .. suspect alternator ?


Go to Autozone or Oreillys for a free scan. You would need to catch the voltage before it goes across the battery to know how much the regulator is sending to the battery. If the battery is that bad you are only measuring battery voltage and not alternator output.

Since most regulators are inside the newer alternators you will need to physically open the alternator to replace the regulator or buy a new alternator. If the battery is rapidly dying you are probably correct about the alternator. Usually a battery at 10 volts will hold 10 volts when it is getting a 14.2 volt boost to its good cells. Not drop like yours is doing.

I replaced the battery 3 weeks ago and everything has been fine. My wife drove around everywhere on Friday. She did not drive the van yesterday. It is now Sunday night. My wife went out ot start her van...


Your alternator is going bad. It should only put out 13-14 volts and therefore is overcharging your battery. This causes your battery to get a dead cell. If you replace the alternator and battery, make sure you check the cables for any shorts.

93 astro van suddenly died


Check that connections are clean and check battery voltage with a meter...If battery has less than 12v in it, likely you have a bad alternator.

Alternator not charging


Check for voltage with a multi meter or volt guage most of the GM trigger wires come from the computer and are only 5 volts. 5 volts is not enough to light some test lights. If still nothing the problem is probably the computer. But it can be manually excited. The two terminals in the alternator on the left of the pigtail (when looking from the front of the van) need + power. the far left is the trigger wire the one next to it is ignition power.
