My water heater quit working on electric! It still works on gas. I checked and I have power at the outside switch but nothing at the coil. I wonder if the outside switch could be bad again, I replaced it last spring? I wonder about wiring the Leeds together and then checking the coil for juce?

Between the switch and the heating element (which I am assuming you are calling the coil), there is a hi-limit/temp thermostat. These can and do burn up as well as just can be reset. If so, then it kills power to the element.....until replaced.
Hold on and I will get you pics.
Here are some pics. The hi-limit t-stat (see red arrows) for the electric element is on the left hand side (the right hand side is the t'stat for the propane side). Press it to see if it can be reset. If not, it may have burned up and needs replacing. You have to remove the rubber cover to access it for replacement.

I forgot to add, if you ever turn on (or leave on) the switch for the electric heating element, while there is no water in the heater, it will burn up the electric heating element. Also it's common to fry the hi-limit tstat at the same time. So even if you replace the electric heating element, you still have to replace the hi-limit t'stat too....since there will be no power to the heating element until the t-stat is replaced.
Here is an electric diagram of the switch, t-stat, and element.

Yep. And it literally only takes seconds! Hit it once by accident and immediately realized what I had done...it was still too late.
Simply put, you can consider the hi-limit t'stat as a fuse. If you will notice in the pic (red and yellow lines pointing to), that the small strip is burned out in the 120v bad one (black wires) but is not over on the 12v t'stat side (red wires).
All you have to do to check it when the water inside the heater is cool, if you can't visually see the strip burned out, is the same as with a fuse. First push in on the reset button at the top of the t'stat to make sure it has not tripped.
1. With power off at the black switch, use your multimeter to see if there is continuity between the two sides by probing the two wire leads where they plug onto the t'stat (green arrows).
2. With power on at the black switch (make sure there is water in the heater first though), use your multimeter to see if you have proper AC voltage on both sides.

I know this may seem simple for the electric heating element, but when you say you have no power at the coil (heating element).... you are checking when the water inside the heater is cool, and has not been heated up to temp by the propane side.....thus the thermostat not allowing the electric element to power up since the water temp is already where it needs to be?
Just checking to be sure.

I had to replace my electric side switch twice. it was replaced under warranty and then 9 months later it was not heating up hot enough and found out suburban had a bad batch of switches and sent me a new one. so far all has been good.
Edit: It might help if I added the link. It's there now.
Thank you for the link. If I turn off the inside switch and have the outside switch on will that be electric only or do I need to have both switches on. Sorry for the dumb questions but the book doesn't tell me much about this.

If you have the Suburban, and only one switch inside, it's for the propane only. The outside switch is for the 120 volt electric heating element only. They are operated totally independent of one another.
As you said, this is not really gone over in great detail in the manuals or PDI's. This is why we have a very detailed FAQ on this. It's a very commonly asked question.
You can have both off, both on, or one on and one off. It just depends on what heating source you want to use......or not use. You can use both at the same time if you need a faster recovery rate (using a lot of hot water)

The LP and electric heating are independent sources to heat the water. One does not require the other. Of course the electric side is 120 volt and requires either shore power or genny running.
I used my trailer last weekend. I did not use water. I did not use any propane. On Sunday evening I got home and unpacked the fridge (it was plugged into electric). Today (Thursday) I needed to measure something in the trailer and saw the hot water heater light was on. The water heater rocker switch must've gotten bumped to the on position upon my return.
There is no water in my tanks. Trailer has been plugged in. I do believe it happened when I got home on Sunday. Do you think since it's a DSI it might be ok since propane was never turned on.
Reading what Wmtire shared, I hesitate to think it's fine - I would guess the element is toast? Thoughts?

If you had no water with the electrical switch turned on to it, it is long gone. As far as the gas side you should be okay. The red light is meaning that it is trying to lite, No propane being on it probably just cycled, I would check your limit on the face of the heater, to see if you blew a whole in the disk. But for sure your element is gone.
Here's another twist to this discussion:
My water heater stopped working on electric this weekend. Switch turned on as usual and water got warm, not hot, then nothing. Switched to propane and all was fine. Thing is, the switch on the water heater jammed in the on position. I figure my problem might be there. Is there an easy way to pull the switch out to check it?

Those electric switches are known for getting stuck and/or failing, especially if not used frequently. I carry a spare in my RV, just in case.
There is a tab on the top and bottom of the switch (see pic below) that you can usually use a thin small screwdriver to push in, then down, and release them. However, the gas and burner tube that is directly in front of the switch can be a pain to maneuver around.
Maybe a fellow member has a 10 second technique and will share it.
