KISS Bally solenoid problem

Working on a Bally Kiss. Turn it on and it fired up. Pressed start and mothing happened. Opened the coin door and did a test and all solenoids fired as they should. i then disconnected some of the connectors to check for continuity and when i replaced them the game would start when the start button was pressed but now no solenoids will fire. What am i missing? I have switched both the CPU and Solenoid with my working KISS and both boards work fine. All fuses checked. Do i just have bad connectors?

Do you have 43VDC at the coils?

Likely bad connectors, especially if they are original.

They are original. Which connector would i need to check or repin?

Check the fuse under the playfield.

Ive checked all fuses. my first thought.

Personally, I repin every connector in the head when they are original.

It sounds like you need to replace the smaller (0.100) pins going to the MPU, or at least J4 on the MPU. Check the smaller pins on the SDB, too.

Those smaller pins are hell to repin

Assuming you have the proper crimping tool, the smaller pins are no more difficult than the larger ones. Good light is must, and for me, reading glasses too.

I agree with Jethro, and a good wire stripping tool is a necessity. Ideal industries has some good ones, or a thermal stripping tool for a Pace machine is better, but those tend to make the area pretty smelly.

Sorry to be repetitive, but for the sake of clarity....when you said you checked all the fuses, just to be sure, there is a fuse attached to the bottom side of the playfield near the flippers as I recall. Slow-blo. Did you check it with an ohm meter, or just visually?

I always check fuses with a meter

The slo-blo fuse on the underside of the playfield, between the flippers, mine blew tonight and all solenoids other than flippers went out.

First thing I thought of, but he's already checked that fuse....see above Post #4, #5, and #13.

Billc479 asked you in the very beginning if you have 43VDC at the coils. What did you measure?

They are getting power. At first they worked in self test then they quit. Fuse under the PF is good.

OK Verify all your rectifier voltages, and voltages at the test points on the SDB and MPU. They are probably good, but its still a good idea to check.

I still suspect the pins in the connectors, especially if they are original. Not else what it could be, especially since you said the boards worked in a different game. Replace all the signal pins going to the MPU and SDB - these are the smaller pins.
