2000 Silverado 1500
2000 Silverado 1500 5.3L engine with approximately 167000 miles. The alternator has been acting up. This is the first day with good with no rain, and not feeling very under the weather. So this is the first time that I could look at the truck to see what is going on. What I found it the wire from the plug that goes to the alternator ground lug has broken off. Will that cause that alternator to act up. Some times you will get a battery warning light and other times it will show that it is working properly. I am wondering if that will kill the alternator and will I have to replace the alternator or will I get lucky and all I have to do is reconnect the wire to the grounding lug on the alternator, and be done with it. Also should I change the belt tensioner for serpentine belt and the idler pulley while I am at it. Since if that breaks we would be stranded on the side of the road.
BTW thanks in advance for any replies. |

Re: 2000 Silverado 1500
Examine the condition of your belt(unless you know how old it is. If tensioner original, then I would replace it when you do the belt. Other pulleys, see if they rotate freely. Without a good ground. You stand the chance of damaging your alternator and killing your battery.

with the wiring secure and proper the dash light intermittent with the battery light on is with these the alternator regulator. these get corroded over time . measure the battery volts . 13.75 -14.25 engine hot ,, 14.75 engine cold . If the voltage is lower then get a NEW not rebuilt alternator. The new alternators have the updated regulator .also rebuilt alt. have a very high failure rate. |

Re: 2000 Silverado 1500
Well the output voltage of the alternator was 11.5 Vdc which is too low. So I ended up putting the new alternator that the wife bought yesterday. I did not get completely finished with the complete installation yesterday. It was getting too dark and the mosquitos were getting to bad also. So I am going to head out a little later today and get the rest of the job done. I am waiting for the temp to get higher so I don't get cold, so I don't get any sicker than I am right now.

Re: 2000 Silverado 1500
Well I had my son helping me with the work on the truck. But he did not tell me that The AC belt tensioner was locked up. I found out when I started the truck. The truck started smoking, I thought it was on fire but when the belt pop then I knew that the tensioner was locked up. So I need to get a new AC Belt and Tensioner to fix the AC. So Now I know last year what was causing the swishing noise was, it was caused by the tensioner going bad that causing the noise when the air was on.

back in the old days all of these ac compressors where mounted up high . they lasted a very long time . rarely did a compressor need replacing. today these are big sellers. so what I AM GETTING AT IS MAKE SURE the compressor is not locked up. |
