Can someone help me rewire my OV-25? « on: December 13, 2025, 06:05:43 PM » Author: Burrito
Mostly to do a floor test lol. Can you help me rewire my OV-25? I want to make sure that the ballast will still work and if my capacitor will be compatible. It is an XFRMR 2 winding ballast with a 120/240 volt input. I'm using a single 30uF capacitor rated at 400 or 450 VAC. The wire colors that I got are red, yellow, black, and white. The ballast has six terminals (three on one side, three on another side).

A ballast with 124/240 input should only have three primary connections (COM, 120V, 240V), so five in total including the two lamp wires. I am confused as to why there would be six terminals. Whichever two wires have the least resistance (pretty much zero) are likely to be the two COM wires, other than that, it gets a little more difficult to identify. Do you have an inductance meter? Do you have a picture of the ballast?

The ballast is in two images on my gallery. One before varnishing and one during varnishing. I don't own any metering equipment at the moment.

Anyone? I really want to get this up and running before I get the housing back from powder coating.

Without any test equipment, it would be very very hard to tell what goes where. I truly would not know how to proceed if I were in your situation.

Should I just rewire it like in the image of my OV-25 before restoration?

Looking at the picture, I can't exactly tell what wires are going where. If you can, then that would probably be the best approach. But be careful turning it on, I personally would limit the current of it with a hairdryer or other appliance in series at first startup to make sure nothing is gonna blow up when you give it full 120.

I think the fixture was 240 volt when it arrived because the center terminal has a spade wire connected to it. This does have a photocell receptacle but it was never wired to the ballast and other parts for whatever reason.

The tag in my luminaire seems to look almost like this image I've provided.

Glad to hear! Sorry I couldn't be of more assistance. I would love to see it once it is all back together!
