I would have recommended calling Sargent Ste, but your previous post led me to believe that the only reason for your dilemma was a flat battery, and having establiehd that, all was OK !
I too have called Sargent on a couple of occasions. For those unfamiliar with the name, they are the main OEM electrical and electronic equipment supplier to the Swift group.
I found their customer service, attitude and helpfulness to be nothing short of exemplary. What I was even more surprised about was that as an OEM supplier, they welcome calls from Swift customers with technical questions and really go the extra mile in satisfying their cause, when they would be well within their rights to refer callers to either Swift’s helpline, or the dealer from where they purchased their van.
A real credit to the industry, and from my experience in terms of customer support, almost a very valuable USP for Swift group caravans (Unless Sargent are also the OEM suppler to any other UK caravan manufacturers ......... Anyone ?)
