sorry for the long feedback, thought I posted earlier
I live in Bonney Lake WA, but able to deliver the truck to Snohomish, I am looking for a competent mechanic that knows a little. Riverside Ford in sumner is ridiculous. Short story for all, I brought in truck for oil and fuel filters. They said my left side battery is in the "RED" needs attention. He asked if I have driven lately. Replied every weekend. Told me to trickle charge it at home. O.K. Mean while in the back of my head I am thinking why am I doing the trickle charge, why not you and how hard is it. So after "I" trickled charged it. The battery was still weak. Duh, had to take the truck back in and have them replace "warranty work". If you see a problem fix it, especially if under warranty. Sorry for the long story.
