Hi guys. was just having a fettle up of my stern grand prix and somehow I've blown the main fuse 250 volt. What happened was I was cleaning the contacts on the coin door switches the bottom of the two.. dunno why just thought I would then I took it off and out ... as you do .. for no real reason and took the door switch apart .. I know I know why I hear you cry and anyways it fell apart and I couldn't get the little bits back in. Well I thought I'd put it back together properly but had'nt and of course shutting the coin door didn't create the required circuit and no sooner had i flipped the switch than I literally blew it . Question other than an new switch and fuse do you think I've caused any major damage. Parts will take a week or two and I really don't want to be fretting on it.. just wondered what everyone thought were.. ps yes I know I screwed up
