OP
Quoted from billsfanmd:
Helping a local Pinhead work in his sega pin. Game is huo and boards look perfect. But it just started resetting. It resets several times after you start it. I did a quick reflow of header Pins on power supply. Still resetting. Fuses all test fine and fuse clips are tight.
I had my dmm on 5v test point and waited for reset. On reset voltage did quick drop to 3 then back to 5v. Anything else to check ?

I had read that there is a adapter fix that stern made to get the dmd direct power so does not draw down the voltage. Ill try to find it and post the link.

here is the link for the fix i had read about

Quoted from Butch2099:
Good point, whole game resetting or just DMD?

The way i read it sounded like its for whole game resetting but could just be for the dmd here is info from stern http://www.marcospecialties.com/pinball-parts-blog/wp-content/uploads/2014/12/sb106.pdf

You could try disconnect the power to the dmd see if game resets with dmd not powered to rule that out. I been thinking also it could be bridge rectifier going up.

Quoted from Evilive69:
My understanding is that this harness just fixes the dmd reset. I had it happen on my MSF and all I did was replace the 2 wire dmd connector with a 5 wire connector. Even though you only use 2 wires the 5 wire connector fits tighter and won't wiggle loose and lose its connection.

Ah ok then i'm guessing is Bridge Rectifier and if that's case it's a easy fix
