My 02 Chevy Silverado is having some electical problems that I can't quite put an answer to. Will show to be charging (14.2v) after jumping it off and running awhile, but after shutting down will not restart, replaced the battery a few months ago, pulled and cleaned all connections I could find for possible corrosion issues. A couple of times the gauges would actually shut down then come back on while it was running like a possible short or loose connection, but so far I can't find one. Any help in diagnosing this would be appreciated. Thanks in advance!

 

have u had ur alternator test or nething?
