Before I email Mezel mods, does any one have any experience with this mod. Just did the install, double checked the connectors. I have not put a meter to anything yet. No schematic for the mod came with it so I’m working blind here which I really dont want to do. Essentially it does nothing.

Yes i had those directions and did the install accordingly.

Did you buy and install one?

yes, and I had the storage facility lit up for quite awhile.

Just did some testing with a meter. I have continuity on all connectors. At node boards and the new control board. What I did discover is that with the game powered off I can rotate the servo motor back and forth but with the game on the servo motor cannot be moved either direction. Does this mean the board is telling it to go both directions at the same time? Only A guess but to me this would seem like something incorrect on the board. As the servo should only see power to it when active. When not active it should be able to be moved manually as if the game was off.

They have been emailed 2x at the same times as my posts here. ONly posted here in the hope someone had the same issue and found a solution. Knowing now that the servo locks up when game is on is only telltale symptom i beleive that will help diagnosis.

Mezel is having me send back the harness, board and servo for them to test.

So they sent me another board and another servo. Failed as well. I managed to find Tim that makes these for them He flat out told me he does not offer any tech support for these. Only thing he gave me of any value was pin 3 and 4 have to see 5v for 4 seconds to activate. Need to test the actual voltage going to those pins. I had asked mezel to test the parts this time prior to shipping but they said they could not. I have to wonder if anyone else has purchased this mod recently and if it worked for them? Will test this weekend. The amber led does flash constantly when machine is powered up. Otherwise I have nothing to go on to find the real problem. This sucks.

Digging a little deeper. I put 5v from pins 1 and 2 to3 and 4 for 5 seconds and stay puft moved. Testing the trigger wires from the led for Storage Facility Lit the wires only test at 2 volts even though the led lights up. So I have to find some choices for 5volts elsewhere that are not constant. I do realize the GI lighting although somewhat constant is 5 Volt. Any other suggestions for 5 volt triggers that stay on for at least 4 seconds?

I hear you. This one actually does now also. My problems appears to be the trigger output From an oem board to the stay puft board is not within the spec to trigger the unit. Ie, to low a voltage even though that low voltage still lights up its led inserts as its supposed to. Would think they would look dim but they dont. So its not the Mezel unit but one of the oem boards their jumper harness connects to. I undid that harness and made a jumper for pin 3 and 4 to trigger off the GI turning off and on instead. Works now. A short game saw stay puft walking a few times. Calling it a day with that!
