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?
-
only 3 wires?
-
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..

NO!
On a pot, it's not ground, +5 and signal. It's ground, other ground and wiper.
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.

Der. For some reason I was picturing a pot wired up in more of a "balance knob" configuration. Which was dumb, considering a steering wheel is not a balance knob. And even at that, it's really a case of two inputs plus a wiper, not two ground plus a wiper. Somebody smack me upside the head with a copy of Electronics for Dummies, please.
