| Hydro Thunder Restoration - Steering Issue Help! (Solved!) |
| (1/4) > >> |
| Shaybe:
I picked up a cheap semi-working Hydro Thunder recently. There was no response from the wheel pick a track or boat, but the boost button works. Once I get into the race the boat goes forward and constantly turns hard right. I went into the menu and did a factory restore, now the boat won't move at all in the race. No response from steering or throttle in the test menu. I tried unplugging the motor like I've seen suggested, but there was no change there. I measured both potentiometers with the multimeter and they both appear to be reading what they should be. I've looked around and found others with this issue, but there was never a solution found. Anyone have any ideas ***issue solved, see post at the bottom*** |

did you calibrate the steering? |

Thanks for the responses Malenko, I tried to calibrate, but I get no response from wheel or throttle PL1, I have not tried measuring with power applied, only resistances One thing I have noticed is that sometimes the voltage reaching the coin mech can be anywhere from 4.66-4.8v This is the same +5v that is going to the steering and throttle potentiometers. Would I voltage slightly lower cause no response? I measured from the power supply and I'm getting +5, and there doesn't seem to be anything it goes through before it reaches those points. |

The slightly low voltage probably won't cause "no response" unless the voltage dips low enough to keep the A/D converters from working but stays high enough for the rest of the circuits. :dizzy: Scott |
