Hello everyone. Have a tech question on our latest BOP restore. It has been playing fine the past few months then yesterday I fired her up to an ENTER report. The error in question is “Check switch/helmet motor”. The helmet will not move at all. Did the calibration and it said error calibrating. Switch test and a physical check show SW67 working correctly. Erik and I did some digging and looked into all the old threads regarding a non working helmet. All the past posts show that people can move the helmet in manual operation..

In our case when we try to move the helmet using coin door up/down buttons we only hear a click when turning on/off. We pulled the circuit board in the lower left bottom and re soldered the header pins. Still nothing. Saw some posts regarding changing the relay but we have not attempted that yet.

Regarding SW67 is says closed when in the Indentation and open when we hold it down with a screwdriver. This seems the opposite of what the posts say and the manual. Kinda confused on that one.

Leaning towards the motor or relay. Any thoughts before we bench test the motor?

Thanks for any comments!

OK. We will test and give some comments as soon as possible!

So no voltage to the motor, checked fuse and it's good. Brand new rottendog power supply so that's out. F116 fuse good and LED7 is on. Looked for a loose connection somewhere and traced to little relay board. Using manual cycle T16I can hear the relay clicking on/off but no voltage even at the connector right next to the relay board. Thinking new relay?

Sounds like a plan. Will post an update!

Yes I have a new one in mine.

Nice cold rainy day to work on this... J2 pins 4 and 7 only have 3.45V at the pins. Same at the driver for the motor. All this talk about RottenDog boards made me head right up to J122 plug on the Rottendog. Seems J122-1, 2 and 3 are at 12V. J122-4 (Head motor 28 Blu-Yel) is at 3.45V. So it seems like power from the Rottendog is not at 12V for Solenoid 28. This is a brand new board purchased for the restore from K’s Arcade.

Why would it work for a few months then die out? Also I was thinking that since pins 5 and 6 are at 12V and are unused on BOP. Think it would be ok to just move the 4 to 5 to get this moving or just try to go with a warranty claim or repair?

I have stopped for the moment. K’s said there is no warranty due to problems caused by motors etc. He said to check the transistor Q20 using the diode test on the MMeter.. Not sure what values I am looking for to determine if it is burnt out. I’m thinking At this point of just putting in my original driver board From the machine in to rule out the RG board. Thank you Bublehead for the replies and help! I have read the manual a few times already but these extra posts are excellent for trouble shooting.

I removed the brand new Rottendog board and put in the original one tonight. Sure enough the motor works great and it is 12V at the test point indicated above. I am going to replace the Q20 transistor on the Rottendog but I am not sure why it failed in the 1st place and if it will be an ongoing issue forever.

As for the original board it has some GI lighting out and some trace repairs on the back of the board, nothing major but should I just refresh the OE board and keep it with BOP? Caps and rectifiers already replaced anyways. Any comments on which route I should take for reliability >>>?

I purchased the Rottendog for just this purpose, trouble free operation for many years. But I am thinking twice about this now...

Sounds like a plan!

So when we did a restore on my BOP we took a piece of the new side decals to the auto paint shop and they matched with the paint scanner. Here is the paint can with paint code. It’s a perfect match but it was all new decals so not sure if you have cabinet fade etc..

Tilt Graphics sells them!

Cleaning up my BOP today and the socket on the upper left ramp Assembly was so brittle it fell apart and split in 2.

It is 24-8821 according to the manual but no luck on a search. Any other alternatives?

Thanks! I’ll check it out!

Yes ordered and installed! Even have a spare JIC

My BOP did not come with a pan, Cliffy sent me one and it is top shelf fit and finish. Agree ti send him an email so he can made one up.
