Was having a slight discussion about this on my original getting stared thread.

Long story short my pool pump Hayward Super II 1 hp pump wouldn't turn on. After checking voltage with a multimeter I figured my pump was dead. Got a pump from a friend that I know for sure works. But after connecting, still nothing. Could this be something with my electrical panel (pool light turns on and outdoor lighting)

Enrico,

When you checked power at the pump you had power or not? If you had power at the pump why would you think the problem is the panel?

The multimeter showed power. The pool light circuit turns on the pool light no problem. It doesn't make sense. The pump I got from my friend works no problem. So what else could it be? Meaning maybe my pool pump was fine and there's some electrical issue.

This is connected with circuit 2 for my pump. (Can't think of what these are called) but circuit 1 doesn't have this. Is it possible this has something to do with it.
 
Enrico,

When I say check power at the pump motor I mean at the terminals inside at the pump connection. If you're getting power at the proper level inside the pump motor your panel and control box must be working properly. If you changed pumps and this didn't work either your new pump is faulty or you didn't hook it up correctly.

When I do that, from L1 to ground I get 123 volts, from L2 to ground I get 123 volts. Should I be showing more power ?
 
Enrico,

That's the right power reading if you are talking about L1 and L2 inside the pump connection terminals. If you are measuring this at the panel the wire could be the problem or the pump motor could be the problem. But if you are measuring this at the pump terminal there's nothing wrong with your panel. Either the pump you have is not actually a good one or you have not wired it up correctly. Most pool pumps are designed to run off 240v 60 hz motors at 3450 rpm. Is that what you have?

Measuring at pump terminal. And that's what I have. I'll have the new pump tomorrow. If this doesn't work then we go from there. But I'm very comfortable with electrical and L1 and L2 (black) are the loads and the pump terminal and green goes to ground. I'm positive it's wired correctly.

Is pump 230v?
If so you MUST measure L1-L2 for 230v
If one pole of breaker or control is bad you will read through windings to ground.
Never check to ground when checking for proper power supply.

So you're saying if I put the multimeter on both L1 and L2 at the same i should get 230 v to read on the multimeter?

If problem is with power supply like I suspect it is you will read 0v from L1-L2.
You will have to start at breaker checking for 230v and work your way to pump

Okay well I ordered a new pump just in case. Worst case I slap a return label on it and get my $440 back. I'm not home until 5:30 az time. Any chance you'll be around then haha

You also need to check that the voltage from L1 to L2 is on the order of 240 - 250V AC .

Definitely going to check this, if I can get someone to do it that's home now, I will otherwise I will wait till later.

Let's assume there is a power issue, as Ted believes there is, which I've been leaning towards myself, where in my wonderful crazy subpanel would I start checking. (pic is above).

Interesting event: I was in the house cleaning up the other day, and the lights in my house flickered (no storm, no winds, no rain outside) and I said to my self "wow that's odd" and I think this is when it started, but can't exactly confirm or deny that.

My steps so far have been:
- Check breakers, Breakers aren't tripped, I've flipped them on and off many times.
- Checked GFCI, outlet works no problem and didn't trip either.
- Pool light turns on and landscape lighting that's tied into the same subpanel (clearly doesn't use as much power as the pump)
- Got a new to me (used) pump from a friend, that I know worked, so I am a suspect of electrical issues, now that I know how to measure voltage correctly (L1 to L2 to get 230 + volts) I will do so.
