2 years ago I replaced my alternator with a rebuilt. Yesterday, while camping at Dosewallips on Hood Canal, my truck wouldn't turn over so I had to push it, and it ran fine but when under load the check engine and brake lights came on. I drove it back to the campground and I added a lot of water and charged it up which only took a little while with the State Park's charger. Today I drove home for about an hour and then hooked up the charger I found the battery was fine. NO starting problems and no dash lights. Do I have a problem or not?
Thanks
Mark
