Sorry for the delay...yesterday was pulling tires to install metal valve stem day...
The install was very straight forward, though I had to make it difficult.
These are the SUPCO SPP6 Capacitors. Got them off Amazon for $13 a piece, though they are cheaper from other sellers, I chose Amazon for the free Prime shipping.
There is one capacitor readily accessible behind a cover on each AC. The capacitors themselves do not care about polarity, just be sure that the wires go onto the RED and WHITE terminals. There is a third terminal on the capacitor (the ground), a brown wire, if you hook to that, the fan will not operate unless the AC is running, which got me it deep trouble, since I did not catch that until late evening and the fan would not turn on (we sleep with the fan on for white noise).
The directions say to remove all power from the coach, I only secured the three AC breakers, and verified no power by trying to operate them...
This is the front AC, remove the four shroud screws and the capacitor box is on the left with four screws. The compartment has enough room to put the capacitor under the cover (must break the tabs off the SUPCO Capacitor), a little deformed when installed, but the cover is only there to keep from accidental touch of the capacitor terminals if doing work under the AC shroud. This is the one I installed wrong...remember, RED and WHITE wires, or the black and white capacitor terminals.
This is the middle AC. Once the cover is removed, the capacitor is on the left, but it cannot be stored with the other capacitor, there is a circuit card in here too, I currently have it zip tied to the wire bundle out side the box, but I may change that, I am afraid that the weight of the capacitor on the wires will cause constant movement riding down the road and eventually break the wires....this is a clear picture of the terminals. This capacitor had all the black terminals used (the white wires), the SPP6 has a piggy back connector, now there are five (5) wires connected to that terminal.
This is the aft AC. It as a ridiculous amount of screws to remove just to get the shroud off. The capacitor is on the right side of the unit. There is a nice size box that holds the capacitor really well, I broke the tabs off the SUPCO Capacitor here also, so it would fit in the cover.
Once everything was buttoned up, I turned the generator on and fired up all three AC units with no problem. The startup of a third unit would cause the power monitoring system to shed power and could never get all three AC units on at once.
Also, we can now run two AC units on the 30 amp site where we are currently staying. The AC compressors seem to start immediately, which means less stress to the system.
