I added some explanation in the previous post but to address this information specifically. Putting multi-meter leads on a system to show volts will not show amps. To read amps you have to make the electricity flow through the meter which means you have to disconnect a wire and hook the meter in the middle. Most meters read a max of 10 amps so don't do this unless you have a shunt.
Where in the system are you reading 16-17 volts? At the output of the solar panels? What do you read at the battery? Test this with the panels connected and disconnected to see if the voltage increases at the battery.
My first guess is your panels are not connected somewhere. Maybe a broken or loose wire, corroded connection, a switch turned off?
What you need to do is follow the wires from the solar panel all the way to the battery checking for good connections all the way.
Another thought, if you are seeing 16-17 Volts at the solar panel that also indicates to me that they aren't connected to the battery. The load of the battery on the solar panels would pull the volts down to around 13 Volts. Do you have the specs for the panels? What is the open circuit voltage or no load voltage of the panels, may be listed as Voc.
One more question, I assume you have a solar charge controller. Have you checked voltage in and out of the controller?
