I regretted leaving the club in 2012 when I sold to help pay for TRON.

After this weekend, I am now a card carrying member again.

As my girlfriend so eloquently put it:

"GOOD. Now don't fuck up and sell it this time"

When it rains it pours!
Joining TFTC in my graveyard of down games is BSD.

One of the optos on the left ramp or at the castle lock is firing on its own.
In switch test, everything appears fine.

But when you start a game, after a few seconds you magically have bats, then castle locks etc.
Has anyone had this issue? Any help is much appreciated!

Trying to get my BSD back in form, any help is appreciated.
I am having a couple issues related to the castle optos.
Ramp shots or secret passages are randomly triggering when the ramp is not hit.
This leads to extra points or bats starting on its own.
Also, the castle release post only works when 2 balls are in the castle lock.
If only one is there, the post drops and pops back up too quickly to allow the ball to release.
Are these issues related?

After some digging, it looks like the castle opto 2 was replaced at some point without a shielded piece.
In switch test, everything works as it should.
The castle optos have been working fine for about a year and have just recently started acting up.
I have attached some photos so you can see what I'm talking about:

Just tried this and I cannot get the opto to trigger without properly blocking its path.
No amount of wiggling of the optos or the habitrail itself would cause a mis fire.

Any other suggestions?

Eureka!

Further prodding has just revealed:

Touching the solder points on the back the black part of castle opto 3 on the blue board causes a mis fire.
Is this the transmitter or receiver?

Plan of action is to reflow solder on the two points connecting the opto to the blue board.
Correct or no?

Reflowed solder on the opto board and problem solved!
Even the disappearing castle lock post is functioning properly now.

One more issue to resolve to get this thing playing 100%:

The drop target.
Have a look at this - what a strange piece in the reset plate assembly !

The issue I am having is the drop not falling with enough force to trigger the microswitch.
I have used a leaf switch adjuster to fiddle with the switch arm and haven't been able to get it to click.
I also notice the switch plate has some play and I can move it around.

Should I replace the microswitch or maybe it is the rusted spring not having enough tension?
I tried removing the spring so the drop stays up, but then you can't access video mode.

The switch arm seems to be floaty and besides not triggering, it also can get stuck on the drop target screw.

Where do you see a penny? That looks like a regular old fashioned house key.
Actually not all that much different than the pic in the manual (#8) ... hehehe

I will try to find the proper reset plate assembly, swap the spring, and probably a new microswitch as well.
That should work ... I hope.

Found the reset plate and spring, but the part # for the microswitch yields no results.
Can I use any standard microswitch ?

Thx

Thanks

Thanks fishrace.
Picking up a new reset plate and spring soon.
Then I'll get to fiddling with your advice.
Cheers
