I have a lord of the rings pinball that blew a fuse for the flippers. When i replaced the flippers the left coil melted. What can I check to see what caused this. Thanks for your help.

The driver is short and needs to be replaced too i guess .

Q15 transistor probably blown according to the manual and here is where it is located on the Power Driver board (see red arrow). If you have a DMM you can test it to verify but most likely it is blown and causing the coil to lock on when you turn it on or start a game. Fix this first before replacing the coil otherwise it will melt another one.

Awesome advice. I will take a look to see if it is blown. So totally a stupid question for you guys but what is a DMM and how do I use it to test the transistor? Thanks.
