I just got a Vector in great condition, but I'm having an issue with the front left row of drop targets (defenders). At the start of the game all drop targets come up, meaning defenders 1-6 and x,y,z. Defenders 4-6 should drop after coming up (at power on and again after pressing the start button), but do not. If I complete x,y,z in order one of the 1-3 defenders drops as it should, but all 4-6 defenders come back up.

I'm running the v5 ROM and I don't think that would have anything to do with it as I'm guessing many of you are using it as well for the added skillshots, scoring and enabling unused speech samples.

I've attached an image of how my 4-6 drop targets are wired if anyone is able to verify against their table.

Thanks everyone! Looks like this is going to be a great table!

Thank you. The solenoid tests all work as expected (setup and drop of targets) and numbers all match according to the manual, but the solenoid expander board has been making some strange buzzing and crackling noises. I found another post where someone said that it had to do with the power supply and the voltage it supplies to the feature lamps. His issue ended up being a fried bridge rectifier. I will keep digging.

On the Solenoid Driver A3 board (AS-2518-22) TP's 1-4 test within range. TP5 ("All Coils") should be between 40-50VDC according to my research and I'm reading 13.2-13.7. Table is playable though. Still just having an issue with the 4-6 defenders not dropping when they should and coming back up when they shouldn't after completing the x,y,z drops. If the coils are running at 1/3rd of capacity might that explain some of my issues and also make slings and flippers a bit weak? Feels like a stretch...

Thank you mjalexan & vec-tor. Sorry for the delay, I ended up blowing the 1A fuse in the playfield and it took me a while to track down. Well actually it appears that someone had put in a 2A, so I replaced with a 1A slo blo and I'm back in business. I was not looking at the rectifier board at the bottom of the cabinet which is pretty dumb as that's where the main power comes in. -I just didn't realize. My readings from the bottom are: TP1 6.86 TP2 233-239 TP3 14.6 TP4 6.85AC TP5 43.8-43.9 which all appear to be in range.

I actually have had the game lock up a few times on me. Usually of course when I am doing well and likely engaging more solenoids. Power off and back on seems to do the trick. Sometimes I have to wait a few minutes.

I'm going to try to roll back to the old roms and see if that makes a difference on the defender issue.

Just wanted to provide a quick update. Resolution was a bad solenoid driver board!
