I just bought a used 7186 Turntable. What I can not find is will the turntable index at 7.5 degree? I also bought a 5 stall round house that has the stalls 7.5 degrees apart form each other. Is this Turntable and Roundhouse compatable? Isee taht a 7286 Turntable can index at 7.5 degrees.

Welcome to the forum, John.

Hi John, and welcome to the forum.

Do you have the original blue box with two red buttons to operate the turntable?

If the answer is YES, connect the three red-gray-red plugs on the turntable to the corresponding three red-gray-red sockets on the blue box.
Then connect the yellow plug on the left (or the yellow socket on the right) of the blue box to the yellow socket "L" of the transformer and the brown plug on the turntable to the brown socket "O" of the transformer.

If the answer is NO, then let me know, as I can say you how to make your personal operating box at a low cost.
If you connect the feeder track to one of the other 4 tracks (I mean the ones different from the 6 tracks at 15 degrees), only one of these 6 tracks is made live.
The movement of the turntable is stopped automatically when reaching the next track. At the same time this track is made live; thus only one of the shed or parking tracks can carry current at a time.

Hope this can help you.

Hi John,

the color of the wires is important only in order to identify the different electric circuits and not mix them up and maybe make short circuits. You need one yellow plug and one yellow socket plus one brown plug and one brown socket. All of them must be of the OLD design (you can find them on eBay). Then connect the yellow and brown wires with plugs to the output of the transformer rated 16 V AC (the output used for the solenoid accessories and for lighting).
And finally: YES you do not need to power up each of the tracks into the roundhouse (you need to power up only one of the other four remaining tracks).
