Question about Chevrolet K2500

1 Answer

Hello. I installed a Bosch alternator in my vehicle below back in November of 2005. About a month ago, the voltage gauge on the truck started to register below the normal "14 volts". At the same time, the battery "idiot light" would pop on. After driving the vehicle for a little bit, the gauge would return to normal and the idiot light would snap off. To make a long story short, it was deemed the battery was bad so I replaced the battery. Now, the same sympton is back. I just drove into work with the guage well below 14 volts and the idiot light on. As I parked my vehicle, both returned to normal. Am I lookinig at an alternator problem? Sure seems that way. Suggestions?

Check gauges light came on for voltage and it went to low. Changed battery gauge went back up for few min and went back to low. Alternator check out ok.

Just because the alternator checks good off of the vehicle does not mean it is charging when on the vehicle. You need to check battery voltage with the engine running. At idle you should have at lease 13.4v, if not your alternator is not charging and you need to find out why.

I have charging problems replaced alternator twice

Is your voltage regulator internal in the alternator? If not, you may try replacing that since it regulates the voltage being put back into battery when used by the car. Make sure there are no things remaining on when you turn vehicle off. An item that was installed by a third party like a radio or driving lights or similar stuff could effect the draining of a battery. If you replaced the battery, be sure you get one with the most cold cranking amps you can find. You may also install a voltage gauge in car to check your voltage as you drive your car. Cheap batteries that you may purchase are exactly that, cheap. Investing in a good battery can help and remember if it goes bad prematurely you can bring it back and get a pro-rated price return on it depending on the quoted months listing on it. For example a 72 month battery is suppose to last 72 months+ and can be returned or prorated towards a new battery. Alternators are also in this same type of group. You want to by a decent one because the cheap ones are bad. Many Autoparts stores will test both of these items for free for you. I suggest having one check those parts and that way your not replacing things that could possibly be still good. It could be something else completely causing the problem.

Alternator Problems, help!

First snug up belt to alternator. With engine running check voltage at battery...should be 13-14 volts. If not check connections...both battery connections, ground wires etc. Is battery good? Sounds like a short though.

Truck will not turn over replaced ignition switch and cylinder,its as if there is no power going to alternator. no remote start. if you keep turning ignition key it will start finally. does not happen all...

Hello! There is a Technical Service Bulletin (TSB) # 02-06-03-006B written that addresses this issue...Dated November, 2004...It concerns the way the battery cables are connected to the posts...Loose connections cause improper battery charging and intermittent starter cable continuity....The TSB mentions that the bolt that holds the cable connector in-place is either stripped or too long...The Bulletin also mentions the charging voltage...Running voltage must be greater than engine off voltage but less than 16 volts...A function of the Alternator...If the battery is leaking, the alternator is overcharging...Take the vehicle to an authorized GMC dealer and have the TSB installed if necessary...

You can check the battery cables (both - and +) for tight, clean connections...If you have a voltmeter, set it to read +12 volts...Measure battery voltage with engine off...Record reading...Start engine and measure again...Voltage must be 1.8 - 2.0 volts higher...In both measurements place the meter probes directly on the battery post and not on the connector...

It seems like there is most likely a bad connection between your alternator and your battery I would look into replacing those wires. That is far more likely than that many bad alternators.

The gauge in your truck reads the alternator output. Following are the possible causes:

1. Belt is slipping
2. Battery is shorted
3. Poor connection at battery or to frame
4. Alternator failing

The fact that it came back after turning off the heat and lights, I suspect the belt, and would start there.

I definitely agree with motor1258's suggestions, but from the trouble code you got, it sure sunds like an alternator replacement is in your future. If you have a voltmeter, and the battery has enough charge to start the vehicle, you can check the battery voltage with the vehicle off, then start the vehicle and check voltage at the battery terminals again. If the voltage readings are essentially equal, the alternator is not charging the battery. (Voltage at the battery posts with a good alternator should read around 14 volts.)
I would not pull a used alternator from a 14-year-old vehicle to use as a replacement, no matter how "new" the salvage vehicle looks. After all, you'd probably get a 14-year-old alternator.

My gauges and heat dont work on my car and the check engine light comes on

This may be related to a loose battery cable or alternator concern, low voltage can cause these concerns as well as an alternator problem, also this could be related to the body control module, Go to a Kragen, Auto Zone and have the battery and alternator tested, it's free, let me know the results.
