The right upper flipper has given out. The lower right flipper works great. I replaced the coil and still no response. The coil is getting the right voltages. Any ideas?
 
Normally it will not be a coil problem. Weak flippers scream EOS switch adjustment. End Of Stroke. It is the switch on the flipper plate that turns off the high power part of the coil so the low power can hold the flipper up. You want it to engage at the end of the stroke and release the switch at the last moment.

Also a flipper rebuild would do wonders. I just did a complete flipper rebuild on my Terminator 2 and the difference is simply amazing.

Someone had welded the coil stop to the flipper plate at a bad nagle and the stop was torched to hell >.<
 
Board trouble?

I did a flipper rebuild on the upper right flipper and it still would not fire. To be sure it wasn't a flipper issue, I swapped the upper and lower right flippers. Now, the rebuilt flipper from the upper spot is working great in the lower spot and the working flipper from the lower spot will not fire in the upper flipper spot. The upper flipper is getting the right voltages. Is this a board problem? The machine was given to me by a friend and didn't have a CPU or driver board. I bought a rottendog board which is working great. If this is a board issue, is anyone familiar with the rottendog diagnostics?

I reviewed the manual and it looks like to switch that controls the lower right flipper also controls the upper right flipper. Makes me think it is not a board issue.

Thanks for any suggestions.

The "switch" you are referring to is a double switch next to the flipper button you hit with your fingers. The first contact fires the lower flipper, the second contact fires the upper flipper. First make sure that the second set of contacts in this switch still have good metal contact -- if not file them down or replace the switch.

If the switch is good, each flipper is controlled individually on the driver/circuit boards. Chances are very high that it's not the CPU board (since as you said, it's new). However the driver board has several transistors that control the flow of electricity from the switch and ultimately deliver power to and back from the flipper.

Start at the switch and work your way around with a multimeter. Nice work verifying that it's not the mechanical part of the flipper.

Progress?

The right lower and upper flipper are now were both getting the right voltages. As soon as I pressed the right flipper button the flipper fired once and went out. There was a slight burning smell. When I go into the switch edge test, the right flipper is not recognized when I press the button or close the switch. The switch is making contact.

Would a blown fuse make that slight burning smell? They all test as good.

Any reason other than flipper switch error that the right flipper would not register in the switch edge test?

Photo of the right flippers on your whirlwind?

It would be a big help if someone could post a photo of the underside of their two right flippers so I can try to analyze whether or not I have a wiring issue. In the photo on Internet pinball database, it looks like there is a wire from the flipper connected to a lamp holder that I don't have. The photo gets blurry when I enlarge it and it is hard to see where the wire connects.

Thanks!
 
Here's pics of the right front and right back flipper on my Whirlwind. I know what you're saying that it looks like the wires are going to a bulb socket, but its not the case on either flipper. I could only upload lower resolution pics, but have 5mb pics of each if you need them. Hope this helps.
