I am changing my coin acceptors from IDX X-10 to Microcoin QL on my vac with Dixmor LED 6 timers. I wired the black wire to 24v , the yellow and blue to Neutral (common) and the Green wire to coin timer pulse. the issue is the coin acceptor accepts the coin but never passes the pulse to the timer for the timer to start. checked all connections and everything is ok what else can I check.
