Hello,

I posted this in the DM owners club, but thought I might try here too.

I just picked up a DM that has seen some better days. It powered up when I got it but would not start a game. Half the switch matrix was out and I was able to fully restore that to function including the claw in test mode. Now that I am further along in getting it fully functional again I had a couple questions I wanted to check. I know I have issues on the PD board and Flipptronics board, and I am waiting on the components to fix those. I am now trying to clean up bad splices and wiring that I have noticed so that I don't just burn up the new components on those boards once I replace them.

1. Once the switch matrix was working I quickly discovered that the right ramp diverter was not working. I suspect this was the culprit that took out the lines in the PDB. It looks like the coil was recently replaced (before I got it) but I want to make sure it is wired properly. The wire diagram from the manual says that there should be two power lines from J107 running to the coil (Red/BRN and Red/BLK)

Edited from page 110 of the DM Manual

It appears only the high power is wired.

Only the Red/BRN is connected

Should I add a daisy chain from the nearest low power coil (Right Jet probably) to the power lug on the diverter coil with the high power connection? If so, wouldn't that energize the rest of the low power string with high power? Can someone post a pic of your diverter coil so I can see how it is wired?

2. Each of the flashers has a large and small resistor soldered to it.

The colors look different in real life vs this picture

When I put what colors the bands appear to be into a resistor calculator, Brown:Grey:Gold:Gold, I get 1.8 ohms with a tolerance of 5%. The bands appear to be the same on both the larger and smaller resistor. All of these look like they were added later in this games life, at least the smaller ones do, and they are all electrical taped (poorly). At the very least I plan to replace the electrical tape with heat shrink. I just wanted to confirm that both resistors were necessary or if I should remove one or both of them?

Until I get the rest of my components in, this is about all I have questions with at the moment. Thanks in advance for any insights on these two things. Have a good one.

Thanks for the reply! Glad I am not going crazy, I thought it was wired correctly but the diagram threw me off.

And the resistors on the flashers seemed odd to me too. I thought it was either to extend the life of the bulbs or like you said, to reduce the intensity of them. But I am probably going to remove them if they are not necessary.

Thanks again, have a good day!
