Take alternator off and have it load tested. Sounds like it's leaking.

    If you have an analog meter

    1. Put it on AC on the battery

    2. Start the truck

    3. Put the meter at lowest to highest.

    4. If that ****** moves your alternator will kill this battery

Dash lights going haywire and engine tries to stall.


This sounds like a low voltage problem, so yes check the charging system first. At 1500 RPM with all the accessories turned on AC blower set to highest speed and headlights to high beam you should have at least 13.4 volts at the battery.

I pack my car this morning and when i came back to stat it it couldn,t.so it was jump started. i drove for less than one mile and and it went off again. i recharged the battery again, i drove...


3 possibilities are:
  • Dead cell in battery; a battery with a dead cell won't accept a charge from the alternator
  • Bad alternator; if the car will run on it's own without stalling, the alternator is probably still good; if the car stalls you may have alternator problems
  • Bad starter; (assuming you've ruled out alternator problems) a bad starter will start when the car is cold; once warm, it requires more power to engage than the battery has therefore, it needs a jump start
I'd advise bringing the car to a shop (most autoparts chains will do a free electrical system check) and have the electrical system checked.

99 suburban wont start, power to starter, only clicks. new starter. lights all work dash warnings seat belt alarm etc. owned for four years never had any issues.


If you installed a new starter and your getting battery volts at the starter wire on the soleniod switch while trying to start the engine, then you bought a bad starter, Good luck, Gary

Charging system erratic


You need to Check the Belts for Tightness and replace the Battery Cables. When you Replace the Cables, you will need to Grind the Area where the Cables attach to Make sure that they are Contacting the Area Completely. A wire Brush will work very well for this. If the Belts are worn, they will Stretch out and will not allow the Alternator to charge the Battery. If you need more Help Just let me Know! Please Rate My Response! Thanks!

Will not start, no dash gauges light except "low gas level"


I have a '99 dodge dakota, 4 cyl, 5 speed manual. While researching a no start problem ran across possible solution to this problem. If no guage lights show when key truned to on position then normally a bad ignition switch. With fully charged battery and working ignition switch guage lights should slight up then go out when ignition in "on" position. Try shaking the key back and forth.
