The T-Rex no longer eats the ball even though the adjustment for it is set to yes. A factory reset and swapping back the old ROM make no difference.
T-Rex never eats the ball though the setting is on: head not centred on its switch
Cause: The T-Rex head was not centred, so it was not closing its centre (home) position switch and the game would not run the eat sequence.
Checks
- In diagnostics, run the T-Rex motor and watch whether it stops at the centre and the centre switch registers.
- Check the T-Rex direction relays, the motor voltage and the limit switches.
Fix
- Drive the T-Rex back to centre from the diagnostics menu so it sits on its centre switch (and adjust the switch if it does not close there).
