I am more of an arcade guy, but picked up a Road King the other day that is having a few problems. Just looked at it quickly and found the following problems.

1. Start a game, and 2 balls will shoot out. I imagine this is a switch adjustment in the trough?
2. Right flipper (FL-17636) does not work at all. It's completely dead. This is different than the other one and took some photos of both. Any suggestions on where to start?
3. Top and right pop bumper not working during game play, but will fire in test mode.

Any suggestions/help would be greatly appreciated!

Thanks for all the help so far. I had a chance to look at this a little bit more today and still had a few questions.

#1. The two trough switches should be closed when the balls are in the trough and open when not in the trough? If that's true, then they show up in the switch test as closed.

#2. Noticed that the coil only had one diode connecting the outside lugs. I installed 2 new diodes and went through the guide. Is there only one fuse for both flippers and that's on the flipper power supply board? If so, it checked good. I cleaned the EOS switch and the button switch. Tested for 50 volts and got 71 Vdc. Coil did fire when grounded to the middle lug. Tested ohms and got 4.1 on one side and 360 on the other. This seems out of spec from the guide, but not sure what it should be since it's a FL-17636. Any other suggestions?

I have 71 Vdc on one side of the flipper switch. Tried grounding the switch to see if the coil would fire, and it did NOT fire. There was a little spark, but the coil didn't fire. I did have continuity from the flipper switch (ground) back to ground.

I appreciate the help on this. What's the next step?

I think you are right. It looks like the contact is missing on the right switch. I did test for continuity when the switched closed, and it does beep.

Thanks for the help on this. I will order the switch and see if I can get these other problems figured out as I wait for the part to come in.

Finally had a chance to install the flipper switch and the flipper still doesn't work. I did noticed that if I pull the flipper up, it will stay up until I release the button. Any other thoughts or items to check?

The EOS is pretty pitted and beat up. I will order a new one and replace. The flipper looks like it was hacked in and wondering if someone can take a look at the photos and see if anything looks out of the ordinary.

Does the diode need to go from wire to switch. Looks horrible the way it's mounted.

Thanks again.

(I will tackle the other problems once I get the flipper working)

Thanks, Andy_B. The photos really helped. I replaced the EOS and lane change switch and cleaned up some of the wiring, and the flipper is now working. Do I need to install a 2.2 uf cap on the EOS?

I also got the pop bumpers working. They just needed cleaned and adjusted. The two ball kickout was an easy fix, because I had 3 balls installed instead of two.

I have a couple more problems now. The left and bottom pop bumpers won't light. I replaced a new bulb and still no light. What's the best way to check if it's the socket, wiring, or something else?

I am missing the top-left segment on the credit display. Is this bad resistor? What's the best way to trouble shoot this, too?

Thanks again. Excited to finally play a few games on this.

I got the lights working on the pop bumper tonight. The connector to the PS is flaky. I will need to replace it when I have time.

The same segment is missing on the first two numbers on the credit/match display. It's the top left (vertical) segment. Is there a resistor that I can check or something else?

Still no luck with the missing segments. Any advice?

Also, what is the detour R exit switch? Can't find it in the manual. This flashes when the game starts.

Figured out why I couldn't spot the detour R game is missing it. Can someone take a top and bottom photo of the switch?
