Looking for some help on where to connect this wire. Was loose when I got it. Gonna replace the orange cap this weekend and want to wire this up properly. I believe it is on 38v line on schematic. Looks like it connects to a bridge rectifier. The ground is connected so should I attach on the bridge rectifier the ground is hooked to? If so what leg do I connect to? Thanks

Quoted from Biffbar:

On mine, it connects to the back left diode bridge (as seen from the coin door, 38 V non-controlled solenoids). So the loose wire goes on the diode bridge terminal which should already have an Orange-Blue-Blue wire, on the opposite corner from the green ground wire. There may be a raised bump, a rotated terminal, or a plus mark next to the positive terminal.

Thanks Biffbar will check it tonight and see if my wiring matches. Game works, but I wonder now if this being disconnected causes non controlled solenoids (flippers, up kicker) to be weak.

Quoted from ForceFlow:

System 1 games don't have any caps on the transformer panel. It's system 80.

Yes, mine is Sys 80 it is Haunted House. I need to check the readings on non controlled bridge rectifier for short. The ground connection was loose too when I looked further. Then I will fix the ground and solder to the place Hawknole and other suggested. Will let ya'll know if I succeed or fail.

I picked up a Solar Ride and the displays work, but the small transformer is putting out ~80v AC on tab 8, through the 69v fuse. It shows continuity to the connector on the power supply A2J1 but I get no AC reading on the 2 pins where 69v should be. A2-P1 pin 6 = 69 volts AC (blue/wht/red)
A2-P1 pin 7 = 69 volts AC Return (org/wht/red) Anyone ever see this on their machine? I thought the 69v was needed for displays to work but does not seem to get to the power supply board....but displays work. Also I get 80v off the transformer. I guess I should check bottom panel diodes and the bridges again but thought they were ok...and score displays are on. Any help appreciated.

Quoted from CactusJack:

Are you checking the 69 AC across pins 6 AND 7 together (not is respect to ground)?
Your displays would not be working unless you had the 60VDC and 42VDC . Unless, of course, your game has been upgraded with LED displays.

CactusJack, each pin separate using ground pin on black and red on pin 6 or 7

What playfield angle do folks use on your Haunted House? Mine when I got it is 6 degrees measured on the playfield...but makes hitting the ramp hard

Looking for some guidance. Had a party and Solar Ride was on for 1.5 hours. Played fine until near the end of that time. Then it started making these weird squelching sounds. It also lost the free play setting, but I could add credits and get a game to start. The bad sound persisted. Original board with 7404/7405 replaced and battery damage repaired. Power supply has NOT had caps replaced. Sound board is brand new from Boston Pinball. Everything worked fine before and during most of the party. Just happened near the end. I suspect the power supply, have the kit and will replace the caps.....but wonder if there is something else. I also plan to repin connectors. Video below of the sounds.... https://www.facebook.com/scott.guthrie.779/videos/2050609218325347/

Update Oct 16...Replaced all the power supply caps and the noise/squelch went away. There is still a hum but i think that is just the transformers. Will do the repin on connectors and hope that keeps it going. Love that Solar Ride

For the remaining hum should I replace the line filter? Also I heard some people whack the transformer with a hammer and that can make the hum change or go away...any thoughts?

Has anyone worked on a solution for the older sys 1 to allow modification on the existing sound tones? Was wondering if there was a way to modify the sound on the existing board, or use the multitone, or aftermarket to get different sounds. For instance if you had Solar Ride and Dragon and wanted to distinguish the sounds between them. Something other than adding MP3 triggers or more exotic solutions.
