Taxi - Help

[tomdotcom]

Post a pic of inside your cab where the cabinet flipper switches are. It will be pretty obvious if there is a microswitch there. The switch has a long blade with a square end that goes by the leaf switches. If it doesn't have that style, then the other guys board ideas might be relevant.

Deadly - this part # didn't come up on RS website?

Sounds like the other gents are on to something Jow. I've never worked on a Taxi before so I have no idea about your particular issue.

That sucks - it appears ratshack doesn't stock the optocouplers anymore. I called two stores and they also had no listing for that part number.
Sorry my man.

It's just a basic opto-isolator. Something like a 4n33, 4n22, etc... should work. I would want to take a look at the data sheets to be sure that the pinouts match but it's safe to say that you could make a general purpose opto-isolator work in the circuit.

If it were me and the game does turn out to have micro-switches I would fix what's there unless I had to replace the switches in which case I would convert it to use opto-isolators.

Here are the pics for those who asked. Sorry for the shitty cell phone quality

Microswitches, so there is no optoisolator on the interconnect board. I would check the switches, if they are good then I would check the circuit that contains Q46 (1J8-9, 1J10-8 and 1J10-9 wires) - which handles the switches.

Those microswitches should control the lane change feature as well as the high score entry..make sure the blade is centered in the leaf switches, and test them in game to see if they work.

Joe, the wire on the switch in the first pic is broken off and it looks to be out of adjustment. ( not centered on the button).

 

[kastawaykid]

I agree with gregatron. The wire is off the switch on the first picture and the switch is also not centered.

The wire off the switch on the right wouldn't effect the left though, right? Sorry for the dumb question.

It could cause a problem if the wire being off caused a break in the daisy chain for the switch matrix. In any case... I would put that wire back where it's supposed to go, adjust the positions of the switches and go from there.

I forgot about this thread. I resoldered the wire and adjusted the switch... still nothing. Whats next?
