you should have 3 wires on the pot, the outer two should read 5v, the inner one should go from 0-5

if not 0-5, check the connector into i/o board.

download schematic, and check voltage coming out of analog port on i/o board.

avcc = 5v , agnd = gnd

check to make sure you have +5/+12 going to i/o

did you go into test, and do jvs test from there?

and were you able to run the JVS test?

What wiring diagram are you referring to, if the link provided is not the correct one? BTW, the JVS I/O pinout is here: http://triplemoonstar.brinkster.net/the ... ockid=1718

the basic wiring diagram should be the same.

Do you have a Crazy Taxi or a Crazy Taxi High Roller ?

What part # is on your I/O ?

What does the JVS Test say? Does it report no I/O found ?

If no i/o found, is there power to the JVS I/O ?

Yes I am able to go to test mode. also the JVS I/O power is up and have its power to CN7 and i slo try CN8 both CN7 and CN8 will power up the JVS I/O

Then i went to test mode check the input for the buttons.

everything works fine except the ACC/Brake and Handle.

what did i do wrong?

thanks Guys !!!

I have the Crazy Taxi Sit down. and my board is 837-13551 without - 92.

i look at the web and seen only able to find 837-13551-92 what's up witht he -92 are they the same?

It found all the keys tested ok except the ACC/BRK/ HANDLE they all have funny number like dfh...and its jumping when i move the other keys...

if you see my video you can see the dfh flicking...while i am trying the other buttons.

thanks thanks
