Mrbill08 got my Mad Planets running smooth and I got all excited to get everything hooked up.

Started up a game and my ship just sat there spinning on its own and wouldn't stop. Eventually, I got it to stop. Just coincidence I'm guessing. Now, when I spin, it acts completely erratic. It just spins somewhat randomly.

Does this sound like a bad IC on the interface board or a bad optocoupler?

Thanks.
 
Take it apart and check the solder joints on the opto board, and clean the opto. There is no IC, just the slot opto. Make sure the harness connector pins are clean and the wires making good contact with the pins.
 
I'll check again.

I was referring to the ICs on the interface board. Thought something had maybe gone bad on there.

Its possible. You need a scope to verify the outputs from the spinner's opto, and to verify the operation of whatever logic chip that reads it.
 
can you give me a close up shot of where the wires connect to the spinner board? i can't get any movement on mine and want to make sure i have them in the right spots.
 
yes i've been thru the manual. mine was a conversion bowling game that i also rewired a krull harness for.

i believe mine is wired correctly and i've replaced the opto board and i get nothing.
 
Fudd. I'll take care of you. I'll be in there anyway. Schematics are great, but sometimes you just need a picture.

Fudd,

Here's those pics. I just fixed my problem. Make sure to check the ribbon connector on the interface board. Mine was loaded with green oxidation. I put a new female connector on and all is good.

can you get me 1 more where it plugs into the trackball pcb on the door? i have exactly what you have and even a new opto board and no go....i'm guessing red is +5 and black is ground and the other 2 are directionals.
 
Here's another pic. Let me know if you need to know how to match the colors here to what I think you're expecting to see.

Can you do me a favor? My trigger switch had a green wire hanging out in the open when I got it. Does that plug into the same connector pin as the blue wire or does it go somewhere else?

was that a mach 3 joystick? the mach 3's had 4 wires. blue,white are trigger and ground....orange/yellow were for the 2 thumb buttons and not used in MP
 
The MP and Mach 3 use the same joystick. I have a green and a blue wire only and not sure where the green wire hooks up at.
 
courtesy of cnlmoores website...you only need the 2 wires in this pic...and yes when it plugs into the same connector and the other wire
