I have not been driving the truck as much as I used to, various reasons. Went out to take off on Saturdaythe 7th, and it would not start. Had enough juice to operate the remote locks and every thing else. Just got that click click click. Figured it was from not being driven enough. Hooked up the charger and it charged up in 30 minutes or so. It is a sealed high performance one, got tired of the old one leaking all over everything and corroding stuff. Drove it for few miles over to friends house for bbq, then home no problem. Went out this morning Tuesday the 10th and the same damn thing. So I have a question....is there a short in the system or regulator allowing it to drain while it sets there. The guage shows it charging while running fine. And I have let it set longer than that before without this problem.
