With most DVM's, set the meter to 10 amps and move the lead to the 10 amp position. If you do not you will blow the internal protection fuse for the lower amp readings.

Thanks Jim, so I just checked the current using the 10 amp position on the DMM and I read close to 6 Amps (see picture). When I read the open circuit voltage it's 12.8VDC. This is with the panel disconnected from the controller. The current looks fine but the voltage is not high enough to get the controller to charge the battery more than a few milliamps even when the battery is under 12 volts. It's almost like this solar panel has a built-in regulator of its own. I can not see underneath it to read the specifications or brand, so i will have to remove it.
