electrical advice

so I got 3 new HEP si280 UNI ballasts to replace my (2) ic660s. I am still using a ic430 to power 2 lamps.
lamps are 80w
I have (2) of the HEP ballast working fine. But the 3rd is giving me problems...

Right now it is the only one NOT on. I switched it to an outlet that was def on, and still no good. This happened when I originally wired it, but I switched the order of the 2 purple wires going into the ballasts and then it worked all last night.

I am using some kind of easy wire hookups that I bought with the ballasts and power cord..

any ideas? they are all "color wired" the same (as in 1 and 2 slot on ballast has red wire, 3 and 4 have yellow, and 5 and 6 are purple. red and purple go the left sides of lamp, yellow goes to other with a jumper connecting.


help! )

Should have a wiring diagram on them. Can you shoot a picture of that diagram and post it here?

The yellow is the common for all 3 lamps. It jumps from aocket to socket on one side correct?

Here is one correct wired one

Here is right side wiring ( the first 2 are from the ic 430 the last 3 sets are from the new ballasts)

You have three 2 lamp ballasts and you are trying to run 8 lamps off of them. The math doesn't work unless you are using common core.

 

[1mbrews8]

lol!

no, i have the 3 HEP, AND still using the ic 430 for the other 2.. )

annnnnyone?

Are you still having problems with the ballast?

 

[1mbrews8]

Yuppppp

 

[wds1215]

If you have one yellow to each end and the two blues and two reds to the other. Have you swapped those lamps with two that are working. Try the two lamps that are not working in a socket that is working. That ballast is marked 7/8. The pic that is marked right side what two are 7/8 ? Also what two in the picture marked left ?

 

[1mbrews8]

The #'s on blue tape tell me which lights each ballast control.

So the ballast marked 7 / 8 controls the last two bulbs out of 8.

Since they're brand new bulbs, I have not tried switching bulbs into another ballast to see if the bulbs are bad since they were new though that could be it.

I did switch the plugs from the quick release into another ballast and it still work so I do not think it'd be wiring?

But it was a few days ago so I'll have to try that again.

 

[wds1215]

try swapping the lamps if they light up then the ballast may be bad.

 

[1mbrews8]

K.
these are the results when I take a ballast and light bulbs combo that is working and mix it with the combo that is not working.

Using a working 2 bulb wired setup (from 3/4) and plug that in to the "non-working" 7/8 ballast = 3/4 bulbs still light.

Plugging wired bulbs from 7/8 into working ballast 5/6 = bulbs do not light.

So that leads me to believe it is either the bulbs on 7/8 are bad or the wiring.

Next I would have to switch the bulbs with another group to see if the bulbs are bad..

so i swapped bulbs and still a no go for #7 and #8????

I am at a loss... I can't figure out what diff the wiring would make or what I would change??
