Hi, I have EFI Live for my LS1. I own a 03 Duramax with an Edge, exhaust and AFE intake. Work truck.
Heres what it started doing today.
OK I've noticed that the Volt meter doesn't go to 13.8 or so until the trucks been running for about I don't 20 seconds or something. Its always been like that since new. I figured they have a relay or a delay built in to the alternator field flash for some reason.
Today I got a not charging message and a low voltage on the volt meter. I got out to make sure I didn't pop a belt. Belts fine I wiggled the Alt plug. No luck about 2 minutes later it started charing. Wierd. I shut off and started 5 or so more times through the day and the same thing it takes betweeen 1 to 3 minuted to start charging.
Is their a relay or something going bad. My Batteries are fine.
Thanks Ed
