pot wires steering wheel atari

Hi,

I have an Atari steering wheel, pulled from a Final Lap cab. Is it safe to say: black wire = ground, red wire = 5v and brown wire = signal?



hng:

only 3 wires?

Kremmit:

A wheel with a potentiometer on it (270 degree wheel) will have three wires.  An optical wheel (360 degree wheel) would have four.

On a pot, it's not ground, +5 and signal.  It's ground, other ground and wiper. 

What are you planning to hook this thing up to?  Should be an A-Pac or an AKI, unless you're using a Dual Strike hack or similar.

I'm using a dual strike hack. I see I've got the terminology down pat..

Zebidee:

NO!

For a pot, the 3 wires are:  Ground (probably BLACK), signal input (probably RED, pre-wiper) and signal output (post wiper).  Looking at the pot from the back, the three pins are:  GROUND - INPUT (ie 5v) - OUTPUT (signal, reduced voltage)

To use an apac, you'll need to determine the eletrical resistance rating of the pot by using a multimeter.

For more directions, look at the APAC page on Ultimarc.com.
