Hi guys I wonder if anyone can help. I have a crown wave 50 in my work place and I just cannot get it to charge. When I plug the cable in it won't even go through the self charge Checks can't get no green amber or red light display is dead. I have just replaced the charger with a brand new charger and still nothing. Charger got 240v going in and can't get the 24v output. I checked the fuse on the front next to the plug in and all is good. Any advice would be appreciated
