San Francisco Rush The Rock Alcatraz Edition Steering Wheel Issue

Hello Veterans,

I have searched this forum throughly and have potentially found the issue to my single sit-down, San Francisco Rush The Rock Alcatraz Edition. When the machine starts up, during self test, the steering wheel fails. When I select a track, car, transmission, and start racing, the steering wheel gets a mind of its own and steers back and forth wildly, making the game unplayable. The common issue it seems here, and which seems to be brought up time and time again on the forum, is the steering "pot" or potentiometer is bad. I wanted to post a fix all end all for this issue, as it seems so common, but doesn't seem like there was too many 'final' solutions on the forum. I wanted to post pictures so I can get some confirmation from the vets who have experience with this problem, and to confirm that my pot is in fact bad, and not the steering board or something else entirely.

Any help from anyone is GREATLY appreciated.

Here is some video of the issue:

It also seems like my gas pedal is giving me some feedback, is that typical?

I am told that either one of these parts will fix the issue:

part # 96-4916-00

http://www.jameco.com/webapp/wcs/st...amecoall&ddkey=http:StoreCatalogDrillDownView
part # 13995

Is that correct?



Once again, any info on this would be great... I want to post the outcome from start to finish so no one has to be clueless on this problem again!

I'm not an expert with regards to this game but did recently bring one that was not completely working and actually had the same issue back to working status. In my case I had a dead pot that was wired wrong. You can google "testing a potentiometer" or something to that effect to get the exact explanation of how to test a pot. In general it goes something like this. Take your meter and set it to ohms. The setting 1 up from the value you are trying to test. So if you are trying to test a 5k ohm pot put your meter at a value above 5k. Your pot will have 3 legs. Like I said this is not the definitive way but with a little poking around will get you the answer you want. Basically try any two posts on the pot at a time. I believe one group will read infinite resistance. One group will show like 2-3K resistance (on a 5k pot). The third possible reading and the main one we are looking for is one where the value moves between 0 and 5K ohms when you turn the knob on the pot. So I guess while you're poking around with your leads you will want to give the knob a turn as well to see if anything happens. In my case when I turned the knob the resistance didn't change at all. I tested a different pot I had laying around to get an idea what should be happening. Once confirmed dead I simply replaced it. Although I did still have the wiring issue. I looked at the rush manual and was able to make an educated guess which wire went to the center leg on the pot. Don't quote me but off top of my head it's the mainly yellow (or white) one with the stripe. Form here I simply wired the red and black wires how I thought they should go. I was wrong though. Here's how I could tell. When the game comes up in test mode as it shows in your video, when you turn the wheel or pot you can see the value represented on screen it shows "01 - your pot value- FD" If your center wire is correct and the other two are wrong, you will see your pot value shows backwards on the test screen. Meaning when you turn your pot to the right the top value should show FD on the screen and when all the way to the left should show 01. If when you turn the pot all the way left it shows FD then you two outside wires are swapped.

Does your Force Feedback work?
A bad steering wheel pot WILL cause the wheel to "hunt" back and forth. They are available from Happ......
My .02$ says its a bad pot.......
 
I've sprayed contact cleaner in my Rush pots and turned the pot back and forth a lot. It cleaned them up to being playable.
 
My force feedback does work. I am going to try and clean them and see what happens. I have ordered a replacement pot from jameco through the link listed. I will let you know if this is the correct part for this machine.
 
Well after putting this off for so long, I finally finished repairing and cleaning up my rush.

I replaced the pot with one I got from jameco. Sure enough, the problem is fixed!!!

Just wanted to once and for all end this thread and archive for future reference for anyone who encounters this problem in the future.


Thank you everyone for all your help!!!!!
