Hi;
Finished up converting a Pole Position cab, (no one wanted to buy it) to a Great 1000 Miles Rally 2 and I cannot get the steering to work. I am using the original PP wheel and encoder and it just does not respond.

I tried swapping the CLK and DIR but that did not help.
I checked and the voltage is present at the encoder board, (wired correctly as per manual)
I tried another steering assembly - NG
Even tried 1/2 a trackball - NG

Also, in the manual, which is in mostly Chinese, it says to wire the potentiometer gas pedal to the 4 pin connector as per the chart below and the chart is missing, there is just a big blank space where it should have been!

I have two questions for anyone up to the challenge:
1- Can I use the PP steering wheel or do I need to swap encoders with something else?
2- Does anyone have the wiring diagram for the 4 pin connector so I can use the potentiometer gas pedal?

I'd hate to have to use a joystick - it would be so lame!

Thanks in advance
Jeff
 
OK, I went back as I remembered that there was a sensitivity setting for the steering and I thought that might have something to do with it. I set the DIP settings for a switched brake pedal and put the game into test. I toggled by grounding the brake wire from the harness and was able to gain access to the settings page.
I set the sensitivity to low, it was on normal and no response. I set it to high and no response. I went into the controls test and it shows a 360deg steering wheel but on the little green squares that are drawn in a circle to show where the steering locations is, 2 green squares are lit, 180deg opposite each other and do not move when I spin the steering wheel.
The hex readout is 4 places and the first, third and fourth places are steady but the second place shows the second character in the hex switching quickly between two different characters......
Do you think the board is bad or is the encoder not compatible??
Thanks
Jeff
 
OK, went back one more time and disconnected the steering harness from the game PCB and still had the same readout on the controls test:

2 green squares lit, 180deg opposite each other and value = ec

and the 4 hex values on the bottom right side of the display are:

hh 8b/c ff ff

In the second position, the b and c quickly switch between each other.

I guess either the boardset is bad or the DIPs are not set correctly.

I have them set as follows:

1 - 1
2 - 0
3 - 0
4 - 1
5 - 0
6 - 0
7 - 0
8 - 0

Any help would be appreciated.
Thanks
Jeff
 
I know that I could just replace the board but I have spent so much time on this one so far.
Replacing the width caps on the WG chassis to get the display right and that was after I spent an hour or two trying to get a G07 to work but the &$#! sync just would not dial in, sooooooo
If anyone has any insight on my steering problem, I would really appreciate some pointers.
Thanks

1 if the encoder is like an atari trackball encoder, you will most likely need a happ type encoder.
If you have a happ trackball laying around try it.

2 the game dose play much better with a joystick.
 
also if you need an encoder hit me up on a pm. i think i have a few in a box
 
I think I have a spare Happ TB, I'll try it tonight and we'll see how it goes.
Thanks for the help.

VERY GOOD CALL!

I hooked up a Happ TB and the steering worked!

Thanks for the suggestion but as always, nothing is easy as the new encoder PCB does not fit on the existing PP steering wheel, the bracket will have to be modified. I will post before and after pics once completed.
I also sent you a PM - Thanks again.
Jeff
 
Done!

Here is the before and after......

I took the liberty to clean, refinish and lube the assembly while I was at it.

It's never easy... ;-)
