So i did a cam swap on a 2006 c6 ls2 corvette and everything went smooth and it started up fine. BUT, its displaying a service charge system and acting like the alternator went out. Could the alternator just go out from pulling it off and putting it back on?? Or is there anything else that i could have mixed up such as the wires that go back on the starter and engine grounds. It also is showing battery low voltage. Any help would be appreciated thanks

Have the alternator and battery checked first, because those are easy and free to do at most parts stores.

Next thing I would check is the plugs and wires, if you changed them in the install sometimes the car isn't a fan of NGK's and upgraded wires...something about "noise" in the signal. Try putting the OEM stuff back if you swapped.

Last thing, check the connections from the battery to starter to car. I have headers on my Vette that caused the starter solenoid to get hot and the plastic around the bolt the connector went on to was melted, so it caused a bunch of shorts intermittently and was a big pain in the *** to find. If that's the case, you have to replace the whole starter assembly (unless you find the solenoid separate, I couldn't) and add in a heat shield.

Good luck.

I've never had that issue durring (3) C6 cam swaps.

I would disonnect the battery and alternator and double check the wires for any problems. Then plug the alternator in 1st, then follow with a good secure connection to the battery.

If it persists, see if your horn works. The "service charging system" has been known to be tied to the horn not working, never really looked into it but it's the truth. Removing the alternator should not cause any problems.

Welcome, happy I could help. I know that issue makes the car do some crazy stuff so it's quite unnerving. Glad to hear it was a simple fix.

Never heard of a LS engine not liking NGK plugs ... it is probably the most popular brand of plug being used in these engines...I've used them for 230,000 + miles without a problem...same with MSD wires .... never heard of anyone having a problem running the good 8.5 mm MSD wires...I just put on a new set after putting 100,000 miles on the last set.

Yeah i have never really had a problem with them either.

I don't know if it's necessarily an LS issue, but it's certainly a Corvette issue. Lots of instances of problems with NGK plugs and/or aftermarket wires on C6's. Can find plenty of instances on CF

Those bozos on CF dont know which end of the wire goes to the coil and which goes to the plug...the site is a major joke...they are experts on high performance floor mats and cup holders though...been working at a chevy dealer which is one of the top three in the nation in vette sales for the last ten years and have never heard of one instance of a problem with MSD wires or NGK plugs in any GM vehicle with LS power under the hood.
