GazB Posted July 18, 2009 Share Posted July 18, 2009 I've got a link unit on mine and i've taken battery of many times and never had a problem, i'd suggest looking for a boost leak. Quote Link to comment Share on other sites More sharing options...
Guest daz 6576 Posted July 19, 2009 Share Posted July 19, 2009 everything is checked visually. only thing i can think of is it vacumn rooted in the wrong way. i will upload a picture of the way its vacumn rooted and you can have a look to see if its wrong. this is the only thing i can think of now. cheers guys anyway Quote Link to comment Share on other sites More sharing options...
