SOURCE: won't start, engine wont rev above 2000rpm

Have the alternator tested. You are providing a low charge to the battery when you jump it and when taking it above 2K RPM requires more amperage resulting in the engine dying and the rough idle

SOURCE: While warming up my 1999 Chevy Venture, the engine

Your right to think about gas but the fuel pumps fail all kinds of crazy ways. The easy way to cheack to see if its the pump is to listen to the tank ( with your ear right against it ) and turn the key on to here the pump come on. If you don't hear anything and the hearing it'self is OK then with someone trying to start the car bang on the tank to shake it and see if the pump will come back on (sometimes they quit altogether and this won't work) The vehical may start right up. If it does the pump is still bad even thogh its running and may not restart as early as the next ry or even quit while running as it already did to you. Rember evven though the gauge says theres gas there may not be be as someone could have stole it and the gauge got bent during the theif. Do'nt look in with a lit match just cause you saw it on TV. Shake the car with a funnell in the fuel cap and listen for gas slushing around. Nothing or slight your out. Listen for the pump this way as it'll really hum in the funnell even full of gas

SOURCE: the car wont charge .

same as mine ,4.0lt mine but its for sundays only cannot afford the petrol ,anyway check the wires on the alternator ,one big one and a smaller one ,now start engine and take neg battery terminal off if it stops then alternator isnt charging ,if so fit a genuine bosch factory exchange unit .but first make sure you have power in the thick cable from the battery though ,sometimes they get a dirty connection in the power distribution box ,if in doubt connect a wire from the jump start point on the firewall to the terminal on the alternator

I have an 2003 Chevy avalanche. My problem is that when I drive the alternator is fine, but when I stop with truck running, the tach shows it going below the normal 550at idle.


increase the idle to above 700. what is the problem with the alternator
Alternators generate power to run the system and charge the battery while a tachometer reads the engine rpm from coil or ignition pulses

New battery new alternator battery still wont charge ??


91 , (is the charge lamp glowing key on, (shoe drops)?????
there are many ways to make it stop doing 13.3v to 15vdc running,
lots. ill list them all..
the 2 stated. in blue above. and.
1: bad dash lamp this lamp boot staps the field current or the alternator is born dead. so is it dead key on, , yes, BINGO.

2: bad alt ground, or starter top bolt , ground to battery bad or loose.
3: bad wires to the rear of alt. all 3.
4: bad battery cables. (or just corroded ends or conn. wrong)!!!
5: alt belt loose or missing.
6: engine hot RPM not 750 to 850 Rpm if 500 BINGO.
and more.

here is the drawing.
IS the sense wire is dead, not 12vdc.???

http://www.fixkick.com/Charging/charge89.jpg


the reg inside can shut the ALT down for.
over voltage
over current.
or if it THINKS(sic) that the batter internal resistances is too high. for ANY REASON what so ever. it will shut down
these protections prevents the ALt. from blowing expensive electronics (all of it) to kingdom come. $$$$$

its a feature.

Charging system voltage low


there are only 3 parts. but the causes are 25 or more.
1: belt missing slipping,
2: engine rpm below 800 RPM (lots of ways ,ask )
3: ALT had.
4: wiring to ALT bad.
5: bad battery or its connections, (wires)
6: bad fuse. see fuse link a11? on fFM page 20?
7: car is PCM alt controlled, it can be bad too. see 2 field wires on ALT and PCM on page 20? below?
8: battery temp sensor bad. making PCM think battery overheats.
the fSM covers all tests above.

pick car here, then pick charging.

Chevy step van turns on but wont start makes


that just means that your battery does not have enough charge to start your car. you need someone to jump start your car or you can take the battery out and take it down to autozone and have them charge it up for you.

Why doesn't it charge at idle?


It depends if the system is RVC/regulated voltage control. If so, there are about six modes of operation. One is, "fuel economy mode". In that mode, the targeted generator out-put is 13 volts and battery state of charge is greater than 80%. There are two other conditions.
Is there a battery discharge problem? Does the instrument cluster give charging system message or warning lamp?
Any charging system trouble codes? My info on your charging system is limited.

Charges ok, battery was replaced, connections cleaned and painted,ran fine for almost three months, then battery went flat again, checked altenator clleaned and greased connections, van ran fine for any...


I would check and clean any wire and connection between the alt and the battery and all grounds. Also check and see if charging voltage is the same at the battery post as it is at the lug on the alt.
