Update on this problem.

Foam didn't work, so I removed the entire VUK Merlin assembly. 4 screws from the underside. I do love how all the electrical components are plugs or sockets for easy removed !! Nice

There is a curved metal scoop, half moon piece that directs the ball into the seat.

I'm guessing that I made too many direct hits with the ball into the metal scoop, cause it had bent.

To fix, I obviously bent it back, but in a clockwise direction. Wish I had taken a photo to better explain.

Now, Merlin is keeping the ball seated, 9 times out of 10. Big improvement.

I'll answer my own post.

Mosfet test with multi meter when NOT installed on board gives completely different readings.

Inserted mosfet onto board and retested, BINGO same readings. Now re-soldered back onto solenoid board and tested working.

Can you tell I hate repairing electronics !!!

Cheers

During game play, LH troll remained up, even in test mode could hear coil powered.

Inspected Solenoid driver board, and mosfet Q7, troll power, with multi meter in diode test, gave open circuit reading - also compared to all other mosfet on board plus the other 2 solenoid driver boards.

Manual suggests part number NTP6412A, however part de-soldered is F3710Z. This part is also shown on  the PPS parts page as a replacement.

I'm in Australia and to buy a $2USD part plus $56USD is crazy!

Part listed in manual purchased locally

Tested with multi meter prior to fitting - reading are completely different. I'm not going to install without confirmation.

Any suggestions Lloyd  - Thanks in advance

Thanks for the replies.
Tried the foam and even re-tensioned the spring on the gate entrance.

No improvement

Almost as frustrating as mode start on Indy!

Finding it increasingly difficult to hold a ball into Merlin Magic.

A sweet shot particularly from the left flipper fires straight through. About the only way I seem to hold a ball in there is from a miss-hit after it hits something else slowing the momentum of the ball.

Anyone else Any modifications suggested???

Thank you

Problem fixed.
Globes removed and not only rotated but also flared out the wire contacts on the base of the LED.

Easy fix 

Thank you from Down Under!

MMR Support [MMR Members Only] / 2 hooded post lights for Castle

« on: December 27, 2015, 01:33:22 AM »

Both these hooded lights don't seem to come on at any stage during the game.
Lamp and flasher test, all lamps work except these 2.
Cannot find any reference in the manual to there correct name or matrix location.
Looking at the wire colours they are wired to operate together. I think
All plugs and connections reseated but no change.
 
Not willing to poke around on a brand new machine without further official technical advice.

Thanks
