I have a Troy Bilt lawn tractor with a 18.5 hp Briggs engine.
Getting it out to get ready to mow.

It was deader than a doornail. Put the charger on but no good. Battery is a few years old so I bought a new one.
Installed and still won't crank or turn over.
Put the charger on again-nothing.

I have a multi-meter but don't know a lot about what to do with it.
I couldn't get a reading on DC volts or amps at the starter.
Not 100% sure I was doing it right.
Tried with the key off and on.
Can I test the ignition?
If so, how?

Any suggestions on how to trouble shoot this are appreciated.
