Help with wiring Berkshire Junction Traffic lights

Hello again,

I wanted to know if anyone has any experience with wiring the working traffic lights made by Berkshire Junction.

I have four seperate lights. I noticed that two of the four have what look like a capacitor on the end of the black lead that goes to the control unit, but two of them don’t.

I was not paying attention when opening the packages to determine if each set had one light that had a capacitor or they should all have them.

I called Berkshire but their phone message says that they are out of town until August. (Bummer). I sent an email, but so far no response.

Please any help, I have massive n scale traffic jams to fix.

Thanks,

SHerman
