[QUOTE="DILLARD000, post: 1050539, member: 74901"] Inspect all Cables+Terminals at Battery + Alternator + MegaFuse + Starter; need to be clean + shiny + tight without broken\pealing insulation. Then do a basic VoltMeter check at BatteryTerminals: * With KeyOffEnginOff, should read 12.2~12.7v = Older~Newer Battery. If lower put Charger on Battery for 4hrs, then remove Charger, check again. If still lower then Battery is bad or you have a shorted\draining circuit. * With KeyOnEnginIdling, should read 14.5~13.5v = Cold~Warm Engin. If lower then likely a bad Alternator or broken Wire\Terminal. 2004+later HEC InstrumentCluster is also a possible culprit; its a NotoriousFailureItem. [/QUOTE]
