Thanks a lot for the tutorial. My old ballast only has one yellow wire. It has the two blue and the two red and the main line wires black and white. Home Depot and Lowes do not have a similar available. One of the store assistants said to just use one of the yellow and cover the other. But only one bulb come on. I will have to check with a local guy who know about electricity, and in the meantime that room has to remain off.

Jon, I have the same fixture and Ballast that you have here. The way you wired this is right but it should be noted that that ballast is for 95w-110w bulbs. I found out the hard way. I'm using 75 watt bulbs. It worked but if I turned the light off and back on, it wouldn't come back on. Called the company and they informed me it was because the bulbs weren't high enough wattage. Thanks for this tutorial it really helped me.

Thank you for this. I had a four wire ballast and was able to adapt your method to the eight wire. Very helpful.

I was really feeling you until you showed what not to do in more detail than what to do i.e. the wiring you made w/ 6 inch strips. I'm not hating but I'm a hands on learner as are many, and if it's visual diagram veers off course then so do I. Good video, it's been over a decade since I've fooled w/ florecent lighting and this was a fun recourse ;D

I just use wago connectors and splice the ballast

Can you shoot one yellow wire into each tombstone openings and just jump both sides with a small yellow wire . instead of making the X cross a simple U reaching both sides.

What is the reason for crossing the blue wires?

[reneeseaton]

The original tombstones don’t allow for extra wire so have to purchase new style.

[stevenboyd]

You didn’t test to see if the power was still off?

What if they turn on and go right back off? I just replaced a 30 yr old ballast. Everything is hooked just like shown. What's wierd if I unhook one light the other works fine. If I have them both hooked up the flash and go back off.

How do you get old wire out of the end where bullb hooks.

[MikeTheBike]

I am trying to find a replacement for my malfunctioning ballast but - like yours - they all have 6 output wires but the existing ones have 7 outputs so Im wondering what to do with the extra "additional" wire? Sorry realise this is a very basic question!

I have 2 4 bulb lights that were removed from an office, mounted them to the ceiling and ran the black, white and green to the plugin, POP trips breaker. Opened them up and disconnected the 2nd one and the first one works, disconnected the first and tried the 2nd light, works. connected them back in series and POP trips breaker. I'm lost! White is neutral, Black is power and green is ground. Any ideas?

This video explained how not to do it. Why not explain how to do it?

This isn't accurate. OLD ballast has 8 wires and NEW ballast has 5 wires.
