If the Ball Return (O) relay doesn't activate the Tilt Reset (TR) relay,
Inspect and diagnose this circuit with Alligator clip jumper wires

pasted_image (resized).pngQuoted from Mully911:do you know what the proper tilt operation should be
pasted_image (resized).pngQuoted from Mopar:If you jumped point to point individually, I guess it's possible you have more
than one issue point to point. Maybe with multiple jumpers, you can jump all
the point to points at the same time, and while jumping, I'm sure you re-checked
the solder tabs..
Or use one jumper to jump over some or even all the switches

Quoted from Mully911:I did jumper all the connections at once and also to each node individually.
If you jumpered from both 25 volt transformer terminals (Black wire and Red wire) directly to the coil and it didn't activate, then the next step is to swap the coil with another one of the same part number, which if you're still talking about the Tilt Reset A-9735 interlock coil, there are 9 others in your Hearts and Spades.
Quoted from Mully911:the switch stack 2C has mixed voltage levels on it, ... so maybe I shorted the two with the clip lead
FYI, this could blow all your light bulbs
Quoted from Mully911:Does anyone know physically which switch on this MOTOR 1C stack, is the one connected to the out hole switch in the schematic?[quoted image][quoted image]
Sometimes there's a motor switch chart stapled to an inside wall of the cabinet.
