Has anyone here repaired this brand of charger? It is the 2 joule, 50 mile range, approx 12" wide balck boxed unit. The closest repair person just rang me back 3 days after I left a message and said that he was back-logged 2-3 weeks, so it isn't possible for me to drive the 1 hr there and wait for it to be fixed. Quoted $20 to look at it plus one or both of the boards which are $35 & $20 each. Can I get these circuit boards myself and more importantly can I get the charger open! Thanks for any help.
