Have a doodle bug .was working fine .tried it the other day and the doodle bug wont work .when i hit the target to start the doodle bug .the doodle bug relay locks on the trapped ball is activated
But as soon as the trapped ball trips the switch under the doodle bug mechanism the doodle bug relay unlatches.if i hold the relay closed the doodle bug works ,but obviously this isnt right. What is causing the relay to unlatch when the trapped ball goes over the button switch within the doodle bug mechanism
Thanks in advance

Got it thanks it was the stop relay .contact must have gotten dirty from sitting . Works good now thanks again guys
