Sprint 1 troubleshooting
« on: March 02, 2017, 03:48:34 AM »
I'm troubleshooting a Sprint 1 pcb. It works properly with just one exception: it ignores the gear. 9312 is ok and I can follow the switch signals till data bus.
Any idea? Coin, start, led, test and gas work properly.

Thank you.

Quick question, when in test mode do you hear a screech sound every time you change gear 1,2,&3? Changing to 4th gear shouldn't make any sound in test mode.

So you were assuming that the gear don't work properly because it didn't change the sound?

This reminds me that I still need to check the Sprint 2....one of the cars is getting insanely fast in gear 4  :?
