2004 chevy trailblazer_lt
Hi everyone, 04 LT, 170k, 40k on the present battery, when I start the truck it often doesn't charge, battery light is on, sometimes when I start driving it will start charging, other times if I shut the engine off and restart, it will charge normally. Had this problem once or twice a while back but now that the colder weather is here it happens every day. Belt is fine and no unusual noises from the alternator. Ideas?
