Hot Water Tank Won't Heat

I am just about at my end with my water tank, I took a cold shower on Monday, I spent Tuesday replacing the bottom heating element and both thermostats, and here it is Wednesday and I still have cold water. I have checked and I am right at where I need to be voltage wise on my connections. Any help would be appreciated.

Welcome to the forums.

With most two element water heaters...... the top element is energized until the water is at the temperature that is set on the upper thermostat. Then that thermostat sends the 240v to the bottom thermostat and element.

If your top element doesn't heat the water and activate the thermostat..... the bottom one will never come on.

Check for 240vac on top element. If you have it then you need to turn off power remove the wiring from the element and check it with an ohmmeter for continuity. It should show almost a dead short.
