03 Silverado Charging System

[WingDing2]

On a recent road trip to my favorite fishing destination my 03 Siverado(120,000m)I had a problem. Got to the lake just fine, woke up to go fishing and the truck was dead no power. put it on the battery charger for awhile, nothing. Replaced battery $100 Truck starts but I immediatly noticed on the Volt meter it was discharging (below 14) lights go dim at stops. I install new Alternator $200. Truck seems to work good now (got me home) but what I am still worried about is it seems to still be discharging intermitantly. The original Battery turned out to be just fine under load test w/full charge. Had no resources to actually check the original Alt. I dont really think I have fixed the actual problem. Any one know if I have overlooked something?

Make sure to pull the bolts out of the connections at the battery and clean them, it's a problems that I have seen with those connections. You should also have the charging system tested for voltage and amp. out put. I have seen some problems with a rebuilt alternator. Good luck.

Deep I believe I purchased a new alternator... the N guy never said anything about re-man and I thought $230 was pretty steep, but considering the location I was lucky to get one period. I did get the $30 AAA discount yeah! I will clean the connections today. Thanks

cheapo clamps on battery. i have decided that the cheap ends are going to replaced on my truck. i buy the replaceable heavy duty ends from the auto store cut the old ones off clean any corrosion from cable and clamp them in place. other thing to do is put some battery protector on the cables.

Jeffreyd, That's got to be the culprit. It's working but, just not how it should, I did not notice if there was any corrosion on the cables, It was too cold out. I did some investigating online, I did get a Re-man... a new Alt. goes for $250

There is not much difference between a good reman and a new alternator

Depends who is doing the re manufacturing. Places like Nappa and Oriely's those only fix what is wrong with then sold. I'm still fighting my charging system on my Camry went through two recons alternators, cables, fuses and still no fix. I must have a draw somewhere. Just may have to break down and see if a diagnostic will trace the problem.

Did not mean to hijack the thread but these charging systems can be a pain.
