The thread title says it all. CHG light on the dash all the time. Well it does flicker when driving. Fully charged battery at 12.7 volts, start engine, voltmeter across the battery terminals shows the same voltage when revving up the engine. My fancy Sears battery charger says "CHK" with red light on "Alternator Test". ENG fuse blows as soon as the engine starts. I don't see any shorts but obviously I'm missing something. Any insight on what to look for? Thanks
