Re: GI problems WCS

For the testing I'm using pin 1 2 or 3 as the neutral side of J115 and I get 7vac on pin 6 of J115, both sides of the fuse and pin 9 of J120- all this with the plug off. With the plug on nothing- dead. I made a really basic low load test with a single GE44 lamp and hooked into pins 9 and 2 (this is the circuit for the string) and it failed.(works on all the others)

What I have found is that this plug was not wired as original - but as half J121 is the switched neutral and the other side is an active direct feed from the transformer I figure it doesn't matter so long as I make sure they line up? (I'll fix this when I get the original wiring for J120). So for my problem circuit it is the active on Pin 9 dying under any load. As you say the triac side is fine- verified by my jumping the pin from Pin 10 on J121 to pin 9 and it works.

As it is load related I reckon its time to test with my GE44 rig, the ac direct from the transformer? I have had the fuse out but I'll check it again for loose caps

Ok let me get the facts here. You should the lighting cam good when
you shorted pins 9 & 10 Together.

So there is nothing wrong with the Triac because the triac is the part
that sinks the ground on the lighting string.
You are right about one thing. It will be a problem underload. A lot
of people fall into this trap. They measure a circuit while not in
operation and it all looks fine.

Make sure your mutilmeter is selected to AC volts. The machine turned
on!

1. Measure on pin 6 of J115. Should be 6 Volts AC. If not then you
will have a problems with that plug or the plug on the transformer in
the bottom of the cabinet.

2. If thats ok next measure for the same voltage on the left hand side
of the fuse F108. Make sure you measure on the fuse holder not the
fuse.

3. If thats ok then measure on the right hand side of the Fuse holder
for the same voltage.( Never check a fuse just by looking at it ALWAYS
use a mutimeter, fuses can look fine but be broken at the ends where
you can see. Also if you can twist the fuse end caps, then it farked
and throw it in the bin.

4. Measure for 6 VAC on pin 9 of J 121.

If you have more troubles let me know what you find in this
description.
