Dodge Repair Questions? Ask a Mechanic for Answers ASAP
The GEN light comes on to indicate the charging system is not operating correctly. When this happens, the battery is not being recharged as you drive; eventually this will cause teh engine to stall and not restart if it is not corrected.
Possible causes include a failing alternator or a poor electrical connection somewhere in the charging system.
Any repair shop can quickly test your alternator to see if it is charging correctly; many auto parts stores can do this (often for free) also.
