    Workhorse 7 VHO bulb wiring

    Hey guys, picked up a WH 7 from Ivan tonight. I was looking on the fulham website but could not find the correct wiring diagram for my 2 x 75W VHO Actinics.

    Can anyone help out ?? Thanks!

    There are a few threads about a year ago which had wiring diagrams. If you search for 'Workhorse' or 'wh7' you'll likely find them. I'd re-do the diagram here but I'm not sure how to do diagrams on this system :-(

    With my WH7, I wired the two bulbs in series. I twisted three red wires togther and capped the fourth one. I then connected two wires to the bundled three reds and put one wire into each hole of the first end cap. Connect each hole of the second end cap of the first bulb to the first end cap of the second bulb. Put wires into each to the two holes of the second end cap of the second bulb, twist them togther with the yellow wire from the ballast. Make sure the join are well twisted, protected with insulating tape and inserted into a colored twist cap used for electrical connections. That's it. See why searching for the diagram will help :-)

    You can also wire them in parallel.

    Simple as:

    3 red wire together
    1 yellow wire

    (the other red is useless)

    Here's a link to one of the threads I mentioned: http://aquariacanada.com/forums/show...&threadid=1105

    The diagram Volitan referenced is for the parallel wiring but is meant for NO bulbs. You can't do it the way it shows if you use 75W VHO bulbs because each red wire only carries 55W. You need to combine two or more wires together. For 2x75W VHO, I would do what LadyP said in a much succinct way than I did :-)

    I just wired up 2 X 75 watt VHO's this weekend using a workhorse 7 ballast. I wired it like the first diagram in the link provided by nickb. It worked like a charm. It was very easy and I no problems at all.

    I wired it almost like your diagram but I put 2 red wires to one bulb and then I put the other two red wires to the other bulb.

    Cableguy, thats originally how I wanted to wire them, id rather have em in parralel rather than in series in case one bulb fails...

    Since it worked perfectly for you than that is what I will also do, 2 reds to each bulb.

    Thanks!
