Default Battery overcharge

Havin some problems with Missbehavin and was wonderin if anyones had anything similar.
Dash lights in the heater/radio area flash off...Then the traction control light goes off and on....Radio cuts completly out and I get check charging system in the dash.....look at the charge indicator and it's showing FULL charge at IDLE? Rev her up and it goes normal....Maybe the Alternator rectifier?Been to the dealer and they kept her for a week and found nothing wrong..[:@]..It's drivin me nuts...
Anyone else had this happen?

Yes Hammeron....would appreciate it......The dealership I left her at has way more impressive stangs than mine to ..Hammeron....no pun intended...They are a Saleen and Roush dealer. I think the alternator is gone though... this is my second one and its a PA-Performance one...I can hear the bearings rumblin just like the first one. These Saleen blowers run em backwards as I'm sure you're aware and personally I don't think they get adequate cooling...I don't care what Saleen says. I spoke with PA-Performance about this and they said if the market was there they would consider building them with the fan oriented in the proper direction for the Saleen installs. I'll have to call em tomorow and see if I'm coverd under warranty as it's only got 1k miles on it.
