From Toyguy @Pinside:Original Post: "Bought a Black Knight pin last year with LEDs & Topper for $1800. It worked well. Haven't played for several months cuz have epilepsy & the flashing lights are a problem. However, recently put on the market for local sale, & the machine works except for the ball launcher. The balls stay in place after repeated resets. The wire connections look solid, have 3 balls in place & batteries are good.
Please help! Tx - rich (Appleton, Wisconsin)"
"<blockquote cite="#4537848">Put it in coil test and see if balls kick out to the plunger lane. If not, maybe a wire came loose on the coil. If that test is OK, remove all the balls, raise all the drop targets and go into switch test. See if all of the ball trough switches register as you roll balls into the drain. If any balls are in the lock, it could also be those switches. It won’t start unless it sees 3 balls.</blockquote>
Status: ran Diagnosis ok until Solenoid Test. None of the solenoids fired. Is this a blown fuse or something else? Obviously am inexperienced with these kind of repairs. Ur thoughts are appreciated - rich
