I have had a problem with the charging system on my GT after taking out of storage and driving it to a car show. It worked fine all day but the next morning the battery was dead. I found no shorts or anything on. I had the charging system tested at Oreilly's and they said the battery was good (whew! Red Top) - bad Voltage regulator. I tried another one... same thing. I ordered a new VR from them and a couple days later put it on and went back to them, they said VR was still showing bad. I didn't believe them and instead ordered a reman alternator from RockAuto. I put it on today and the amp gauge is showing 30amps at idle. I believe everything to be hooked up correctly after installation. I tried a diff VR and it shows the same thing. Would it be high if the battery were fairly drained?? I don't think the alternator should be putting out 30 amps at idle assuming it is reading correctly. Normally, it sits slightly to the right of 0 until you turn something on. Any thoughts? The rebuilt alternator is bad?
