Hi all,
I just installed a new ST-3 head that I had sitting in a crate for the last 10 years.
The wiring looked good and the windings are copper.
When I gave the system a test run (no load), the unit was surprisingly quiet compared to the 3600 rpm unit that I removed.
No screeching and electrical whining noises which both of my 3600 rpm heads made even when unloaded.
I now need to wire the head into my electrical system as two 120 volt outlets (one from each phase). That part is simple enough.
However, it is doubtful that the 4 open connections on the back of the junction box would pass north American electrical codes, so I'm
looking for ideas and pictures of what other members have done to re-wire, reconnect, or change the basic ST design,
Some people have replaced the metal box with a PVC "Scepter" j-box. Others use the stock metal j-box.
Please let me know what you did with yours, and send pictures if possible.
Here's what mine currently looks like....
