Looks like it was completely wiped rather than just RAM-cleared. Or something in the EEPROM corrupted itself so the machine nuked its own settings for safety. if it was fully cleared and then set up it's probably just a wrong setting somewhere.

Either way, you will need to run the setchips and set everything up (again) e.g. jurisdiction, set the number of lines to 9 or 20 lines depending what you want (Tiki Torch allows both), max bet setting (e.g. bet multiplier of 10, 20, 25, 50), variation 99/1/2/3/4 (99 is the lowest RTP at 87%, 4 is the highest at 97%).

I don't know if it's like MK5 (aka MKV/MVP/540) where there's a jurisdiction menu which tells you what's wrong, that used to be the cheat sheet when things weren't right.

Hey, thanks Koni

As you discovered in the program list, there are some ROMs that support tournament mode on the PE+.

There's an old post about it here. On games that support it, the procedure to enable/disable tournament mode is:

PE+ Tournament Mode:
1) Turn and Hold the Jackpot Reset Key
2) While Jackpot Reset Key is held, press the "Change Request" button

The game should flip between tournament and standard mode (and vice-versa).  You do not have to finish the tournament countdown clock, you can do it right away.

I don't think you can do it with any of the multi-game sets, I think it is only available for dedicated single game setups.

Did the 24v LED light come on the backplane board when you swapped the PSU? 

Indeed.  Presuming the first step of the journey, IE obtaining the missing chassis, is successful, the second step is I will order a book.  Hopefully I can find an original or very good copy.  Then comes the part I dread, IE learning the vernacular, and memorizing the correct names of a thousand parts so you guys can actually help me, and then memorizing the sequence of operation.  Boy am I dreading all of that.  Probably Tuesday before I am back on here.
