A while back I bought an operation wolf Jap Taito cab with a gun issue. Shots not registering on the screen so usual problem with this game.
I've been chipping away at the issue and trying to work it out but am at a bit of a road block so hoping to hear from owners of this game.
I have a photocopied manual for this game and it shows the pinout for the gun sensor board should be:
Pin 1: -12v
Pin 2: +12v
Pin 3: Sensor out.
Pin 4: GND.
When measuring my cabs molex output at the gun sensor it is reading:
Pin 1: 0.02v
Pin 2: 0.02v
Pin 3: +12v
Pin 4: -12v
So clearly the wrong voltages at the wrong pins. So I trace the cables back from the gun sensor molex through the cab.
Pin 1 and 2: There is a grey cable that contains a white cable, with bare wire running along the outside of the white cable. At the gun sensor this bare wire heads off to join pin 1, and the white cable joins pin 2.
Pin 3: Blue cable. I didn't trace this one, I assume it leads to power supply as it reads +12v.
Pin 4: Pink cable, leads to the aux power supply and is being fed -12v.
I found this strange as it appears I have the correct voltages to the wrong pins at the molex connector, according to my manual.
Also strange is that pin 1 and 2 read 0.02v at the gun molex, but when traced back and seeing it join on to the gun sensor out pin on the sound board edge connector I measured this and it was about +4v. I can only think the white cable (pin 2 on the molex) is meant to join to the gun sensor and the bare wire is GND.
I pulled the cover off a spare op wolf gun I have and it has the same wiring colors in the same spots on the molex inside, even with the grey cable with white cable and bare wired etc.
So if anybody can help me with the following questions that would really help:
Q1) When your op wolf cab is on, what voltages are showing at the gun sensor pinout on the sound board edge connector?
Q2) At your gun sensor molex in the gun itself, do you have pink, blue, and a grey cable with white and bare wires connecting to the molex pins, and if so what pins do each connect to?
Q3) If someone out there has a jap Taito op wolf cab, can they confirm the above for me as well to see if there is a difference between the US cab wiring, and the Jap cab wiring?
Thanks for any assistance.
