Had the same trouble , I took the couling off and worked the stalk to find the gap between the cotacts to big, just bent them back abit and now all works ok . Hope it helps

Cocked that up ,wrong forum and spelling . Its called linex . Sorry about that , it was late .

Can anybody tell me if they know anyone or anywhere I can get my rocksliders sprayed in lynex in the Sheffield area. I saw one done at a show and it looked smart as well as practical. Cheers
