National 148 with vendors exchange board

Recommended Posts

Henan Mei 7512 develop some sort of electrical problem in this machine last week. I think I was a bad low level tube sensor. Every time I went out to check the machine it would give me an error saying the B tube was empty I would reset the machine and it would work fine for a day or two and then have another problem. I replaced the coin mech last week and just got a call that machine is not giving proper change.

Has anyone developed strange problems with the Vendors Exchange kits?

Found the problem. The 9302gx doesn't align properly with the coin chute. The back hangs about a quarter inch outside the chute
I notice this with some models we upgrade with inone or ucb kits.
The usi 3014a won't fit many mdb mech when upgraded without modification.

I upgraded a 3014 and the only issue I had was that the MDB harness from the validator wasn't long enough to reach the harnesd coming outb of the board. I'm not sure, but I think the inone board is supposed to have a longer harness for the 301x. Maybe they didn't give you the proper length harness.
