I took a TOM in trade, It plays but the trunk does not work at all.
I am looking for someone to walk me through this, I looked up some other threads but the didnt help.
Here is what I know:
Nothing...it doesnt work at all, no movement. Switch error #s 55-58 on boot up. Trunk does not move in trunk test. The board has 2 LEDs that are on...where to start?

Motor getting power ? Motor board getting power ? Wires up through trunk shaft all broken and shorted ?

LTG : )

Sorry, just got back to this...the 4 wires going up through the trunk are twisted and broken off. They appear to be for the bulb and magnet, I ordered a new one. In the meantime, should the trunk still spin with those disconnected?
There is power to the motor board (the red led is on)and the 4 position optos register in test.

The wires that come through the trunk are for the magnet and the lamp inside the trunk. They are not responsible for its lack of movement.

Did you check your eddy switch? When I got mine it didn't work. There's a pot on the eddy board, turn it till the light goes on, then back it off until the light goes out. Should be good to go.

I’ve had to adjust the eddy switch a couple times on my trunk as well. That’s where I’d start. I had to adjust them in the outlanes for Hocus Pocus as well. That’s a different issue though.

If the eddy is not working then the trunk wont move at all?

Go into switch test and sort out switches #55-#58. Not sure what those switches are from the top of my head, but they are probably related to trunk hits, etc.

Go into the test menu and test the trunk operation. You should be able to move the trunk into each position using the menu buttons. this will tell you if the board and motor works. I'm guessing though, once you sort out the switches, everything will work fine.

Switches 55-58 is the trunk opto board. Replace it with the Leon board. Well worth the money

Trunk does not move at all in test mode...
The 4 positioning switches register in test...

Then I would check to see if you are getting power to the motor. Can you hear the motor when you try to turn it? If your trunk motor shows voltage, the grease packed inside the gear box may have gummed up. You'll have to disassemble the motor to clean and regrease.

When in test mode, are there 3 closed switches and 1 open switch? (55-58) check the trunk opto interrupter as well to make sure it is positioned correctly.

Ok, I started this thread a few weeks ago and did a poor job...I should have taken a few pics of the area and had all the simple things checked... Im at the dog beach in San Diego now but when I get home I will take a look .
The trunk did not work when I got the game, the former owner said he tried some troubleshooting with no luck. I will report back. Thanks for the help

Ok. Let's see what you got also posting this issue in the club thread will yield more suggestions too

I would try disconnecting the motor and hooking a 9v battery to it. If it moves it's not the motor that's bad.

#16 1 year ago

It's just a fuse.

Quoted from cosmokramer:

No, it will not. In test mode you can roll a ball over the area in front of the trunk or hit the trunk with the ball to see it the eddy is working. I just had to adjust mine the other day.

If your trunk isn't spinning in test mode it is likely the motor.

CHeck for the resistors and big electrolytic capacitors, common porblems there

#19 1 year ago

Motor spins fine with a 9v battery attatched.

I found this lone connector, I cant find anywhere it may have come loose from. Is this supposed to be plugged into something or is it not used?

Not used.

#21 1 year ago

I would connect a voltmeter to the motor stabs and go into trunk test to see if voltage is going to the motor. And work my way back from there. Prob motor control board issues.
