Hi i have a cyclamatic power plus , it has a fault when the moter kicks in it looses power and the leds on the grip go out? then if i wiggle the key it kind of erratically comes back on again? when the power drains i can hear a feint clicking which i have traced back to the barrel where the key goes in. Sounds like something is shorting and the power is not getting through , seems like a bad earth or something? can i rewire around the key barrel or can i get a new key barrel or is it something else? i have checked all the wiring and it all seems good , so it could be a weak connection in the key barrel ? thanks in advance .....
