I guess a perfect example of me and racing occurred this weekend. I busted my butt getting the grass cut and the tires prepped, balanced, and installed on my duster. I was loading up at 8:30 last night on a hot humid day for a day of racing in 90 degree weather today. Well after loading I went to back my trailer down the hill and the batteries in my truck were dead. I threw the charger on and went in the house to shower and eat. When I went back outside it wasn’t charging so I put the charger on the other battery and went to bed. I got up at 7am and the other battery wasn’t taking a charge So I disconnected them, cleaned them and tried charging them again. 2 amp, 10 amp, 40 amp, start circuit and nothing worked. There was a time when I would have pulled both batteries, drove the 20 miles to get new batteries and install them but not today. It was a humid 80 degrees already so I was done for the weekend. Maybe next weekend.
