Another electrical question

[thvigil11]

Here is a quick sketch of what I understand so far. So my questions are. Where does the black hot go to? Does it follow the same conduit as the pool light? It appears to be a three wire (which explains the red and black sharing the white (neutral) and Green (ground). So at the light, are you seeing all these wires, red, black, white and green? Are there other wires seen here? Possibly a two wire line (white and black) bringing 120 volts in.

A shot of the pool light/ socket area could help.

Hotchef, turn off the breaker to this circuit, double check with your meter that it is dead.
Then remove the wires from the right switch and clean all the corrosion off the wires.
And with the breaker off, put a wire nut on the red wire and black hot wire, you can leave the short black jumper out.
Now go turn on the breaker and check the pool light. It should come on if it is good, and you just determined if your new switch is junk.

unknown at the pool light, it's sealed. It's a rubber cord going into the back of the housing. Black hot I believe is coming from the gfci that is before this box.

The new switch(one on the left) is the pool switch. It's not a cut jumper, just stripped to run around the screw and then over to the spa light switch(right). If I remove the switch on the left(pool) and twist the red wire around the stripped area on the black wire would it accomplish the same thing ?

No, what you are trying to do is eliminate the suspect switch. What ever wires going to the switch need shorted together, in the case of the left switch, take both black wire off of it (from the screws on the same switch) and wire nut together. * Turn the breaker off first*!

Still clean the corrosion on the other wires too.

Would it be possible that there is an issue at the gfi causing this? My understanding is that the white, green and black hot wires are coming from there. I don't see any difference in wiring between the 2 switches that would imply there is a downstream issue but thought it was worth asking.

Next question, is it possible corrosion on the light socket is the culprit? I looked closer today and there is some brown corrosion on the contacts. Would that cause this issue ?

Bob, that's one wire on the left switch which is the suspect switch. It's just stripped where it loops around the screw and then heads over to the spa switch. I think you're looking at the switches backwards and want me to wrap the red around the black on the left switch. Make sense ?

Well, it needs corrected, the hot should be pig tailed with a wire nut and a wire feed to each switch.

In other words, the hot wire and two short pieces of wire under a wire nut. And each switch fed with it's own pig tail wire from the wire nut.

What is between the switch and the light. GFI? Pics of the wiring at that GFI might help. Outdoor gfis can be problematic, especially after seeing corrosion on the rest of the system.
