Alan ;
before you touch anything else , go to WallyMart & buy the plug in alternator tester ($18.95) , it fits into the cigarette lighter plug and provides s dynamic real world indication of what the charging system and battery are doing .
Above idle it should be charging 13.9 VDC ~ 14.7 VDC . the cheapo voltage regulators barely top 13 VDC so if you need a new one , take the time to order up the correct Bosh brand one I posted the P/N to before , I know others have this P/N and will post it shortly ~ DO NOT allow the parts boob to have you anything else as THERE _IS_ A DIFFERENCE ! .
Never , _EVER_ trust the boob behind the parts counter to know what he's talking about ! .
Why do you cay the battery ' fried ' ? .
What is the specific symptom you're having ? .
