Been restoring a Data East Jurassic Park for some time now. Still fighting with T-REX. I had a bad switch on the T-REX down switch and during the replacement both of the wires to the left right motor came loose. Soldered them back on and she hasn't been the same. I think it's wired backwards since it now is going nuts when T-rex is enabled including resets. Thought i had pictures from the restore but i can't find them. Can someone take a look and let me know if it's right or wrong. Thanks for the help! Dan

Thank you. Corrected the title. It's the left/right motor that was rewired.

Thanks for the great work and the great tip. I'll probably include that as an uparade to the game as a next step.

Having said that I'm still not sure it's wired right. The game and t-rex was working good except it was not eating the ball reliably. Found the switch is bad. Replaced the switch. Found these wires to the motor had come undone. Reattached them. Trex is now a mess causing resets. I believe they are backwards and would love someone to do a visual on theirs so I can eliminate that as the cause.

Thanks!

Hmm. Appears to wired the same as mine...
