Title: Ballast Post by: Slapshot42 on May 24, 2014, 03:37:07 pm I bought this 15 watt ballast from SJW for a T8 fixture what has it's own FS-2 Starter.
No wiring instructions and both wires are black, how do I determine which one is the neutral wire ? They are both black... Jared Title: Re: Ballast Post by: johnieG on May 24, 2014, 06:01:31 pm The answer is..Neither! the ballast is wire in series with the hot wire (think of a light switch)
Title: Re: Ballast Post by: Slapshot42 on May 24, 2014, 07:17:13 pm I was locked in on a diagram that Jim drew up for me a National 9 Pull Cigarette...
I think this will still work, I was just focused on one of the wires needing to be designated as "white" neutral. Title: Re: Ballast Post by: Slapshot42 on May 24, 2014, 07:23:57 pm Poor drawing no access to a scanner until Tuesday...
Title: Re: Ballast Post by: Slapshot42 on June 03, 2014, 11:54:07 am Well figured it out...thanks Jim for your patience....the biggest mistake I was making was the type of ac powered device I was using to test the socket with after wiring.
I had my heat gun out when I was heat shrinking the wires. Not thinking about the change I had used that to test the socket since the top half of the machine was blanket wrapped waiting for a lock. Also the male socket from the back is a poor design and I had to use a belt sander to grind down so the socket would fit. A great site for vintage looking assessories is www.vintagewiresupply.com. Lots of old plugs, bulbs, wires, etc. Title: Re: Ballast Post by: Creighton on June 04, 2014, 06:57:56 pm Glad that is sorted.
Thanks for the link to the vintage site. Creighton |
