  1. I can give you a hand with this one bud. No need to start poking around with a test light, your wasting your time. The radio is being controlled by the BCM through the serial data line. I assuming you have a stock radio and there's no modifications done. Let's start there before troubleshooting. Also do you have a scan tool and any codes?

  2. Where did you get this alternator? Do you have a model number? Or take a pic with the back cover off. Have you tried to put the 105 amp back on to see if the problem goes away.. Can you give me a detailed description of what exactly happens with the new alternator? I can help you out but I need the details so I can pin point the problem. I'll have a little time later on to text you through the troubleshooting but for now the info would be a good start.

  3. Check your pins inside the wiring connector for any corrosion. Use a temporary wire jumper from one of the alternator mounts to a good grounding point so we know it's getting properly grounded. Also what all do you have not connected right now? The body, powertrain and the output driver modules have to be connected. A scan would be helpful for futher troubleshooting, sounds like there's an issue with the control signals from the pcm or your new alternators regulator.

  4. Yeah I have a scan tool but have to wait till next week when I put my trans in so I don't throw anymore codes... could you possibly text me so we can talk during the process instead of the site lol

    Yeah, we can do that. But first, give me any details that can help with troubleshooting. Is your original alternator a Delphi AD230 and the upgrade an AD244? How's the belt tension, a little tight? Are there four pins inside the alternator connector? I think I know what's going on, the power coating of your alternator housing.. Pop off the back cover and you'll see two brush clips to the left of the wire connection. The top goes to the voltage regulator and the bottom to ground. If that bottom clip isn't getting a good ground your alternator with not work correctly. That brush is controlled by the regulator to turn your alternator on. If your not sure what I'm talking about, take some pics and we'll go from there.

  5. I was worried about bypassing that fusible link wire.

    Also, this guy seems to use different ground points on his 06 silverado http://www.jrrod2004.com/silverado/bigthreeupgrade.html

    Your right, if your replacing that wire you should protect it. If your just going with a 145 amp alternator, I wouldn't change that wire. Get an AGM battery and connect your extra load directly to it fused within 18" of the battery. Ground your loads as close as possible to one grounding pont.
