I found this ballast in a local metal Recycling yard, It still appears to be in good condition and the condenser that came with it also is looking good (as far as i can tell) but the wiring was in tatters, the fixture this came out of appeared to have been hit by a forklift that was sitting nearby  , I cleaned the ballast and tried finding a wiring diagram for it on the web but had no luck, it is a 35-210901 04 GE mercury vapor ballast. If anyone here can help me with a wiring diagram for this thing it would be most appreciated  

Know what voltage and lamp power it is for ?

Some of the ballasts in my mercury Silverliners and on GE look like this-but no schematic wiring diagram on them.250,400W.

Im not really sure the voltage rating of the ballast, the capacitor is labeled 277v and the lamp looked like it came off a warehouse or something of that sort, the bulb in it was smashed beyond recognition so i dont really know its rating, I'd guess from the pile of glass that the bulb was BIG and thats about the end of my talent in that department lol

The ballast in my 250w metal halide GE lowbay looks like that. That might be what this is, but GE also made lower wattage mercury ballasts that looked like this.

Why does it look like it has two primaries and two secondaries? also how would I wire this thing up for operation? and what is "lowbaly"

I found this on eBay. Meybe it'll help. I think it's 1kw. 

If any of you have something tht looks the same, comapre the part numbers to see whether it is..

The 2 primaries and secondaries are either just for manufacturing convenience, or to allow 240V/120V operation by wiring the 2 sections of the primary in series/parallel respectively. Without an example of such ballast wired up i cant be sure about the latter, but i am sure that both for the primary and the secondary, the identical sections are meant to go in series or parallel

Do you happen to have a picture i could use to get an idea of where everything is suppose to go? that would be very helpful, im surprised google is lacking anything on this ballast other than an ebay offering.

I had second thoughts on its condition, so i pulled out my Multi-meter and did a check on all the coils, the two secondary coils check out at one OHM roughly, and one of the primaries checks out at 2,3 and 8 OHM's but the other side gives absolutely no reading at all, i looked closer at the coils and to my dismay it appears the ballast did not survive in one piece after all 

bump....

I know this is a very old one of my topics, but i would still like to know how to wire this type of ballast up (for future reference) does anybody have pictures of one of these things all connected up?
