Confusion About 12V Disconnect
Hope all is well My solar charge controller is not pulling any amps , it lights up and clearly has power but no amps are being drawn from the solar panels , after review of the troubleshoot tips fr...

read the instructions to troubleshoot and this is what it says (im dealing with both of these issues)
Controller does not charge batteries/Controller shows "0.0" amps charging
Troubleshooting steps:
1. Ensure batteries are not full, charging amps will drop to near zero if batteries are full (meter the batteries, don't trust the display from the controller)
2. Ensure solar panel is clean and is in direct sunlight. An obstructed/dirty panel will yield poor results
3. Check input voltage at controller from solar panel (~18V based on solar panel rating)
4. Check wiring from solar panel to batteries
5. Check for any fuse in-line in the system
6. Perform a hard reset on device. Disconnect all four wires from back of device and let sit for 15 minutes - reconnect all four wires and recheck
7. Replace controller
Moon Symbol on Solar Controller
If there is a moon symbol appearing on the controller then the controller is not seeing voltage coming from the solar panels. The first step here is to remove the wires on the back of the controller coming from the solar panel. Use a multi-meter to measure across the two leads. In sunlight, you should see between 20-18 volts. (this number maybe lower on cloudy days). If you do not see this voltage at this point the next step would be to check your panels and work your way back down to the controller with the multi-meter.
Put the meter across the leads of each panel. The voltage should be very similar (20-18 volts based on the type of day). If one panel is lower than this then there is an issue with the panel. If all are the same then trace the wires back to the controller with the meter and determine if there is a connection issue.

Does anyone know which two leads they are referring to?
