Typically that means you have a bad diode or two (usually open) and are only getting a few amps out of the alternator.
The idiot light just indicates that the battery is supplying the coil, not the alternator. Bad voltage regulator will do the same thing, plenty of amps maybe, but not enough voltage to charge the battery. _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
