Solar Charge Controller

[KarlKontiki]

I have just got a Swift Kontiki 784. The Solar charge controller indicates low battery and so is not charging the leisure battery. The leisure battery is fine though. I checked the battery feed to the solar charge controller and it indicates 0.18V when the saragent unit is off and 0V when the saragent is on. I don’t believe this is right and so believe that there could be a problem with the in line fuse. However I can’t see one. Does anyone know where the fuse might be or if there is anything else I should look at?

Welcome to the Fun

That yellow thing sticking out of the base of the controller is a fuse which I presume you checked?

But he is measuring with the wires removed from controller, so it must be a fault/ bad connection from battery to the controller cable end. It’s in that path, I would use a extension wire and check for continuity from that end you measure, to the battery post. One wire at the time, it will reveal which wire is open circuit.

The cable from the panel should read 18 to 23v, the other pair from the battery should read the battery voltage.
Can't see in your photo but have you got the meter leads plugged in correctly.

That’s the controller fuse. It’s fine hence lights showing low battery. I believe there should be an inline fuse on the connection to the battery as currently there appears to be no circuit from the controller to the battery.

Is the solar controller wired into the Sargent PSU or direct to the leisure battery ?

Follow advise fron Raul

Which Sargent unit do you have? And as GeoffnDee says, is the controller output wired to the Sargent unit or direct to the leisure battery?

If it's wired to the leisure battery, there will be a fuse at the end very near the leisure battery. Check the fuse - with a meter, not just visually. Also check for corroded fuse terminals.
