Williams, 1990Getting awful close to being done with my FH playfield swap.
When powering the game back on for the first time, are there any safety measures to take, like unplugging power to certain switches, solenoids, flippers or anything?
I don't want to screw things up while standing at the finish line.
Thoughts and advice are welcome. I have visually inspected everything, and things look good.
Everything was going great....I had powered it up and everything was working great.
Powered it back down. Installed two new switches.
Then the playfield fell off the rotisserie, at least one corner did, and it came down semi gently on the table on one corner.
MUCH profanity emanated from my workspace, a veritable tapestry of foul language.
I thought everything was fine....I checked the underside and it looked ok, so I got everything back into the cabinet and powered it up.
NOTHING....no power to the CPU board, and now I notice on the power board that LED 2, 3 and 4 are all out. (no 5 volt going to the CPU, right?)
I went through everything on the underside, and found a couple of switches and a coil that might have been touching a bit, and adjusted the wires.
Looked around to see if I could find anything else that was shorted.
Checked the connectors on the power board and the CPU.
Everything looked good.
Powered it up again,
Still nothing. What did I do and how do I get back to the glory of a working game that I had just moments before?
I am guessing at the very least I need a/some new fuses.
and I am hoping I didn't fry anything on the board.
There was no problem with the game prior to the game falling off the rotisserie and the installation of those two new switches, so I figure it has got to be something was touching something...or I screwed up the wiring of the switches....I don't know.
I just know I need your help to get it back to operational. It is times like these that I truly appreciate the limitation of my actual knowledge.
I am not quite following how you ended up with a CPU problem by dropping the PF from a rotisserie. Was the playfield fully plugged into the game when it dropped or bench powered? Obviously you want to check the fuses on the playfield but I would not guess that dropping a playfield a bit (sounds like a mostly minor drop) would be that drastic. Are you sure your not missing something simple due to the freak out factor of dropping it in the first place. I would chill out and have a beer or two, laugh a bit and take a clear eyed look at the situation and start from the start and boot game with out the playfield and go through std check list.
Thanks rufessor. The game was not powered on when it fell.
I am taking it slow, but perhaps that beer I had has made my explanation somewhat less than clear.
The PF was was mostly done. I had powered it up and everything looked great. I powered it off. Then it fell.
1. After the fall I inspected everything, then reinstalled the PF back into the cabinet.
2. The day ended.
3. A new day came. I installed two switches and a coil.
4. I powered it up, no CPU.
5. I checked under the PF, and adjusted a couple of wires to make sure nothing was shorting out.
6. That's basically where I am, still no power to CPU and no lights on the power board for led 2, 3 and 4.
7. Time for another beer?
I just did a Centaur PF swap recently and I powered it up fuse by fuse checking things along the way triple checking things and couldn't get the the GI working also it made a nice electrical smell. Long story short after about 2 weeks of combing over every inch of things taking frustration breaks I remembered I had re wired the coin door lamps and forgot the coin door lamps have to be wired backwards otherwise its a dead short, doh.. Problem found.
The point, I've done a couple swaps now and checked and checked everything on the playfield and the problem wasn't even on the playfield...
The frustrating thing is that it was all working perfectly after the PF swap. Booted up, went into game mode, checked all the coils and switches, everything was solid. The only that changed was the little tumble and the installation of two switches and a coil.
Anyone able to share the best route forward?
I assume I need to check fuses, and start moving methodically through things.
Find which fuse is (or fuses are) blown (if one or more are blown). This will give you the direction to start your search. The LEDs on the power driver board will also give you a guide on where to look.
So I read a bunch on pinwiki last night. With a little help I am methodically going to work through the problem.
The 5 V LED on the power board is out.
As per Chris Hibler, I checked the fuse at 113, buzzed it out of the game, it is good.
Replaced it and removed J116, J117 and J118, then restarted the game. Fuse did not blow.
Checked seating of ribbon cable from power board to CPU. Checked and reseated other connectors.
Based on something I read on pinwiki, which I believe is attributed to Chris Hibler, I am not sure that the installation of the two switches, the coil and the dropping of the PF are even to blame here....but no matter, I will follow through on this one step at a time. I just need to know what that next step is.
Are any LED's lit on the power driver board?
Check each fuse on that board
If the fuses all look fine, check that its getting power (carefully) with a multi-meter (I forget which plug/connector brings in power, but should be shown in the manual/schematic)
Have to sort that our first since that is how the MPU gets power.

The LEDs are lit, with the exception of LED 2, 3 and 4 (5 volt).
All fuses test as good.
arcadenerd925, power comes from J101 I believe.
Checked voltage at J101.
Meter reads 10 VAC on J101, on the top two red wires.
