Picked up a DH recently that has a problem with the gun. If you choose load gun on the skill shot, it will load the ball into the gun but almost immediately the HQ hole fires like it thinks the ball is already in there. A while back I searched the forum topics and owners thread regarding this issue and thought I found something regarding it but can't seem to find it again. As I remember I don't think there was any resolution to the problem that was posted anyway. Any ideas on what to look at regarding this? The gun works perfectly in all other aspects of the game. Thanks in advance.

Thanks Lloyd for the quick reply. I took a quick look for the things you mentioned and the only thing I saw that looked a little suspect was the diode on the load gun switch. I'm not sure of the rule of thumb on which way the banded side goes but this one was not consistent with other ones I compared it to. On all the others the banded side went to the lug with no wires attached and this one was reversed. The switch looks like it was re-soldered at some point so they could have put it on backwards. Does photo look like it's wired wrong? Thanks for your help.

Thanks, I will reverse that when I get a chance and hope that fixes the problem. I will post the result.

I turned the diode around, actually put another one on because that one was a mess but still no luck. I took another look at the other switches and everything seems to be wired correct. The only other thing I can think of is the right pop bumper has been broken since I got the machine. It is missing the yoke and the whole thing is collaspsed underneath and not working. I haven't got around to ordering the part to fix it yet. That switch is in the same row as the gun popper. Could that switch, still wired properly but not registering have any effect on the gun?

Thanks, I will give that a try.

Moving the white wire to the other lug did the trick. It works perfect now. Thanks again for everyone's advice.
