I have an old izip cb26. It worked ok 2 weeks ago. Got i out today. Battery fully chargedd, switched it on and all of a sudden you can hear clicking from within the controller. The throttle seems to have a weird very loose clicking sound coming from within so i suspect it could be the controller. Motor works fine, dash lights come on but all that happenes is that it clicks. What could the problem be ? If its the throttle could i purchase a standard 3 wire throttle and wire it ? Many thanks.
