| How to test a pot? |

I've got a set of pedals that don't work and am trying to figure out why. They connect to a wheel which is a USB device. The wheel and buttons work fine, the pedals act as if they are not present. So I started gutting things. The brake and accelerator are each tied to a pot. Two of the three connectors on each pot are wired together so I believe that they act like variable resistors. There are only two wires running from each pot. And they run to a USB board in the wheel housing. I did some poking around with a multimeter but I don't know what I'm looking for. Any suggestions? I'd like to verify that the pots are working properly and then go after the connections/wiring and then the USB board. TIA. -pmc |

Set your phaser on stu... No, wait. Set your multimeter on Ohms (resistance) Check resistance from the two pins that are commoned to the other pin. Resistance should change as you cycle the pot. |

Worked like a champ. The brake was like 200-ohms (if I got the scale right) and decreased to near zero as I applied pressure (turned shaft on the pot). The accelerator started with higher resistance, but worked similarly. I assume both are working correctly (as I suspected) and now I have either a wiring/solder problem or I have some sort of USB PCB prob. Or, of course, Windows could be messing with me as usual. ;) Thanks for the help. -pmc |

Do you have the correct driver installed? If you don't have one from the manufacturer, you can go to Control Panel > Game Controllers > Add to load a generic driver that might work. -Ace- |

It's a Thrustmaster Nascar Pro Digital 2. It comes with a mapper package which is nice for remapping buttons and controls on a per application basis. But there's no manufacturer supplied drivers. That's one reason why I'm so puzzled that the pedals don't work. I'm not sure what could even go wrong! Pretty sure I tested on another PC once and I got the same result. Everything else works and is visible in the Control Panel without the mapper software present. But pedals are ignored as if they are not connected. An inspection of the wiring and PCP doesn't reveal anything obvious. My next move is to poke at it with a stick and see what happens... Been playing Need for Speed Underground and Outrun but have been using the wheel paddles as digital accelerator/brake. Works OK. BTW, I can't get Spy Hunter to work with a digital accelerator at all. Seems to ignore my key presses. Messed with the controls for a good 30-min to no avail. MAME 0.97. Anyone else have trouble with Spy Hunter? -pmc |
