Because of static conditions, a small percentage of games may still exhibit a 
loss of controls occasionally. If this occurs, a cable adapter (Part # H-23741) is 
included. These symptoms indicate a static discharge problem on the steering 
and brake pot wires. The symptoms may occur more frequently during the 
winter, or in dry, static-prone environments. The anti-static cable H-23741 
connects between the MagicBus Board and steering / brake /gas cable.
 
[ ] 1. Switch off power to the VGM. 
[ ] 2. Following instructions in your manual, access the MagicBus.....board. 
[ ] 3. Disconnect the cable at MagicBus.....connector 3JP15. This is the 
steering / brake / gas control connector. 
[ ] 4. Find anti-static extension cable H-23741, that came with these 
instructions. Check the position of the Z-header on the cable. The header must 
be on the end of the cable that has ground jumper loops. Otherwise, move the 
header to the other end of the cable. 
[ ] 5. Attach anti-static extension cable H-23741 at MagicBus.....connector 
3JP15. 
[ ] 6. Attach the original steering / brake / gas cable to the anti-static extension 
cable.

drive.

performs satisfactorily, proceed with the next step. If the VGM doesnt perform 
satisfactorily, go over your work. Check for loose or improper connections.

drive.
