Bypass safeties in electronic Neon Transformer Answered

I have an older FRANCE PG-1 Series neon sign transformer. It
is a type that contains a SCGFP potted module in top compartment of
transformer. There are a number of leads originating from the potted
transformer, which I am trying to identify.





3 of the leads, black, white and green, ring out as extensions from the input power
posts. This is the 120 VAC supply to the unit.





There are 4 remaining leads


(1) blue,


(1) blue with white stripe,


(1) orange,


(1)orange with black stripe





Can anyone tell me what these 4 leads do and how to
reconnect them, once the SCGFP potted module is removed.


My purpose is to convert this transformer for use as a
Fractal Wood Burning System

Provide a load. This could be a resistance or reactance. I'd try wrapping wire around a lag bolt or something and putting that in your circuit.

Some of my neon xfmrs all work without that "electronic safety" you have in the neon xfmr you refer to.

I wonder how or where you got that xfmr ?

A picture would be nice.

Not much you can do if everything is tarred over. There are chemicals that are designed to eat away the tar, but I would imagine that they eat away the electronics as well. If it has an internal GFI, or protection circuit like that, when opening up the transformer, it may be in a separate part from the tarred transformer itself. Then you can really easily mod it. Otherwise probably not much you can do.

Does it do that when a neon lamp is wired to it ?

Give it a load then.

What its trying to do is get a current to
flow. You could try and load it with a very large high voltage resistor, you have 30mA of drive capability, but see if will drive 9 meg or 1mA to begin with - you'll have to use high voltage resistors, or a big chain of lower voltage resistors. Most standard resistors are 200 V operation, so you need 41 X 220K
