I just got a Sega Super hang on that seems to be having input problems and the vibration feedback motor doesn't work. Everything else appears to be in working order.

I've replaced all of the potentiometers and made sure that each is getting 5v. The Break input works perfectly. The throttle input works great, except I believe that it isn't maxing out. The steering input doesn't seem to work at all. Every once in a while I can get it to turn sharply to the left, but nothing more.

I've tried reseating, and making sure all of the connections are good. I've tried calibrating in the input menu, but I find I can't get the steering angle to go past 50h and I can't even get 7ch or 80h to come up.(the manual says to adjust to 80h) I've search this problem up and down and have not found any sort of definitive answer. Help would be greatly appreciated.

Also if anyone could please take a picture of their handle bar wiring that would be great. I have a two wired plug that goes to nothing.
 
Whats the color of the wires on that 2 wired connector your looking at?
 
I personally don't have any experience with Super Hang On but I happened to have acquired a boardset recently for like $40 from some local CL ad.

From what I can tell it's part of the input I/O harness on the boardset as the gray and green wires are bundled together with most of the control inputs on the filter board.

Would that green wire happen to be a different gauge than the gray one?
 
its actually a green wire with a white stripe and the wires are the same diameter

Oh ok. Well there is one green wire with a white stripe on the cable connectors between the filter board, but its on a different set of connectors....but no gray wire bundled with it. Possibly something that is fed to the force feedback control board?

I've got an OutRun, and it's quite similar to Super Hang On, so I took a look...

Are your replacement pots 5Kohm (or close)? If too low of a value is used, it may pull too much current.

Were you careful when replacing the pots to put the three wires onto the proper lugs? There are 3 connections: 5V, GND and the wiper. With power on, the voltage on the wiper (the middle lug) should vary between 0V and 5V as the pot is turned.

According to the schems I found, there's only 1 two-position connector going to the controls, and it's for a turbo switch/button.
EDIT: correction, there may be another one to power a light in the speedometer.
ANOTHER EDIT: and, of course, the wires for the shaker motor.


On the force feedback... This looks quite similar to OutRun except it's lower voltage. There should be a 4A fuse in the bottom box that fuses power to the motor. If it's OK, check voltage at each of the 10000uF caps down there. One is for audio power, the other for motor power. Should be like 12-15V at each cap. If that's good... it might be your SSR (solid state relay) board. It's a little PCB with a 6-position and a 2-position molex connector it (and a funny looking flat black component).

To clarify...

According to the wiring diagram in the manual, there are three different 2-position connectors going to the controls:

1) For the "meter lamp" (presumably a light for the speedo). This should have yellow connector housings, and the wires should be purple w/white stripe & light green w/white stripe.

2) For the 12VDC motor. This should have white connector housings, and the wires should be red w/white stripe & white w/blue stripe.

3) For the "turbo switch." This should have red connector housings, and the wires should be light green & white.
 
Update....

The two pronged connector that is not connected is for the light behind the speedometer. the light is missing, so is it okay to leave this unconnected?

I can not find a 4a fuse on the board that powers the vibration motor but the capacitors check out voltage wise.

What exactly is that weird black component on the solid state relay board?

Also checked the pot to make sure I had it wired correctly. voltage on the middle prong goes from .80 to 4.83 is this correct?

Yes, quite alright to leave unconnected.

OK. If the fuse (where ever it is) was open, you wouldn't have voltage on one of the caps.

That is the the actual solid state relay. Think of it as an electrically operated switch. When it gets a "high" signal from the game (~5V), it turns on and allows the (seperate) higher voltage to go to the motor and drive it.

Also checked the pot to make sure I had it wired correctly. voltage on the middle prong goes from .80 to 4.83 is this correct?

That sounds reasonable enough, although I might expect it to do closer to 0. However, I'd need to check on mine to verify.
 
Okay, thanks guys for your help so far. I'm still getting the same results. I tried changing pots again. These are the things that I'm 100% certain on.

-I'm getting 5.08v from the power supply.
-my potentiometers are wired correctly and are getting 5v
-I have the shaker motor DISCONNECTED
-I have the light that goes under the speedo DISCONECTED
-My angle values for steering go from 0H to 52H with a bunch of 3ch values in between.
-My angle values for acceleration and braking are the same. I've tried twisting the pot all the way and it changes nothing. The values do not go smoothly in correlation with the turn of the potentiometer, if that makes sense.
-I'm getting roughly 13v off of the big blue capacitor in the bottom of the cab
-The game itself seems to operate fine. All menus are accessible.


Something about the way the values are not maxing out leads me to think its some sort of power issue, maybe with a capacitor? I'm wondering where I should start looking and what values I can expect from the big blue capacitor and the smaller black one that sits next to it. these are located in the bottom the cab next to the two smaller pcb boards(not the main game boards)

Darren also pointed out that it could be my solid state relay, where can I find on of these?

If this doesn't pan out for me, what are my chances of using a working Hang On board in this cab with the existing wiring. I don't care about the vibration motor, but I would like to reuse the power supply.

Not me. The caps in the power filter voltage for two things: the shaker motor and the audio amp. One of them being bad might be the cause of a shaker motor not working, of having no/bad audio... but will not effect not the analog inputs.

If all of the analog inputs seem to be nonlinear, and don't go full-scale, I'm thinking perhaps the ADC or the multiplexer (a couple of ICs on one of the the PCBs, the bottom one I think)

EDIT: according to the schematics, the multiplexer is a 74HC4051 @ IC117, and the ADC is ADC 0804 @ IC116.

Again, the SSR suggestion was with regard to the non-working shaker motor. Won't have any effect on analog inputs.

Darren,

Thanks a ton!! I checked out the two spots you pointed out for the IC and ADC. Sadly someone has been here before and really fudge up the traces and it looks like they tried to fix the problem already. I'm going to replace said parts and go from there.

Thanks again
 
I got a Super Hang On board lying around, supposedly working, or at least that was what I was told. I can't test it at the moment because I have no harness....

Just have to replace 2 caps on the top board because I knocked them off with my feet....lol too much junk laying around.
 
Trying to troubleshoot a Super Hang-on with the following issue: during game play, throttle and brake appear to have no effect on player's velocity. When throttle maxed, speed goes from a flickering 92.x to a solid 93. When the brake is pulled, the rear tire rendering changes, but that's it. In test mode, both of those controls range through to spec.

Thoughts on where the issue may be? Thanks in advance!
