Let me know what you find out, mine just did the same thing. I changed old coil sleeve, and it worked fine for a few plays, then broken again. I plan on changing coil next to see if that remedies the issue.

I had to figure that out today as well. Not sure if I did it correctly, but to ground out the tab, yours will be Q26 for ramp diverter, refer to pg. 3-5 in manual. I placed an alligator clip wire on the tab at the hole, then touched the other end BREIFLY to ground braid or leg of the machine. I had to do that to test Bazaar eject coil, and it fired. Note you will get a small arc or spark, I was hesitant at first, but I think I did it right. I searched high and low for info on how to do that too. Checking the switches before and after the diverter too is a good idea as LTG suggested. Check the resistance on the coil too, that may help others with more experience than I do to help you out.

I think you may need to just rotate the coil a quarter turn so the lugs point out towards the right side (towards pop bumpers). You wil need to remove the coil stop to rotate it.

Been there myself!
