Hello all, Just got back from our first official Colonial Travelers Rally in beautiful Wyoming, PA Grace and Dick Missett were wonderful hosts, the company was welcoming, the weather was phenomenal and the food was too.

Upon arrival at Frances Slocum State Park, pulling in to register, a quick "flump" from the engine and a slight rpm change, the alt light began to glowed dimly I thought I threw an alternator belt, I had been struggling with a squeal and was believing I overtightened it...kept the engine running, and took a quick peek, she was still spinning. Once plugged in I flipped the boost button to charge the engine battery...I've kind of gotten into the habit since I left the radio on once or twice and killed the engine battery. Upon leaving the glow was gone, I wrote it off to gremlins...108 mile trip home was uneventful. Checked voltage when got home because engine was slow to crank when I restarted, only 12.5 V, turned on lights and voltage began to drop. Advance Auto Parts tried to spin it on the bench but failed the "light test" and would not proceed.

My engine and "rebuilt in China" Delco only have about 250 miles. could leaving the boost switch on while plugged in prematurely burn out the alternator? Or is this a replace till you get a good one scenario? Anything else I should check? rewire radio into house circuit?
