Two problems related to alternator/generator/regulator have been reported for the 2001 Chevrolet S10. The most recently reported issues are listed below.
Second complaint for same issue. Dealer says that nothing can be done without vehicle backing up my claims, said to bring it in when vehicle is acting up. Alternator type sound coming through radio, all lights flickering (dimming and brightening), truck stalled two times last night. Truck gets nothing when you try to restart, no lights, no alarms, no engine click, no turn over. . . Nothing at all. However, 20 minutes later truck will restart, with everything reset and clock reading 1:00. Did this last night twice, once last week. Called dealer today and they said that they couldn't test it because the computer reset itself when the truck shut down. Bring it in when it acts up again. . . . . Even though there is no gaurantee that I will make it to the dealer without the truck stalling!!!!! that's comforting to know!!!!!!.
Alternator noise feeding through radio on occasion after turning vehicle off and restarting noise appears to go away. Flicking lights on instrument panel and radio, started out of a parking place with this happening and the truck moved 5 feet before losing all power. Truck would not start, no lights or alarms. Left key in the ignition after 20 minutes all alarms and lights returned to normal and truck started with 1 turn of the key. Can not take the truck to the shop until it is making the noise again, because they will tell me that they can't find anything wrong. What would have happened if the truck would have lost power when I was doing 65 miles an hour on my way home from work?.
