mfewtrail Posted July 1, 2004 Report Share Posted July 1, 2004 Check your connections at the alt and battery to see if they're tight. Also, check your grounds in the engine bay and clean any that are dirty/corroded. Quote Link to comment Share on other sites More sharing options...
supreme_style21 Posted July 1, 2004 Report Share Posted July 1, 2004 Check your connections at the alt and battery to see if they're tight. Also, check your grounds in the engine bay and clean any that are dirty/corroded. Â And have them check the battery as well. I've had nearly new batteries go bad.

syknesss Posted July 1, 2004 Author Report Share Posted July 1, 2004 could the alt be related to my cold start misfire ? Quote Link to comment Share on other sites More sharing options...
GP1138 Posted July 1, 2004 Report Share Posted July 1, 2004 could the alt be related to my cold start misfire ? Â I'd have the ICM and coilpacks checked. I noticed when my coilpacks needed replacing my alternator wouldn't charge properly. I also had that same problem before I replaced my alternator.

Baddflash Posted July 1, 2004 Report Share Posted July 1, 2004 I had the same problem on my old Lum, I replaced the battery and the problem went away. It was last winter that this happened. Quote Link to comment Share on other sites More sharing options...
backinblack Posted July 8, 2004 Report Share Posted July 8, 2004 Check your negative battery cable. Especially the joint to the chassis under the battery tray. Quote Link to comment Share on other sites More sharing options...
