RV FEATURE
Trailer plugs need to fit securely to work properly . If your plug is loose , try widening the gap in the pins to about 1mm with a small screwdriver .
If none of these actions resolve the issue , it ’ s a good bet you have a dodgy inline fuse on the positive power cable . These things are diabolical and are the cause of many issues . Again , you will have to hunt this down . Find the power outlet and look behind the panelling it is mounted on . The fuse should be reasonably accessible . The fuse may also be placed near the battery .
Inspect the fuse . It will be obvious if it is causing problems as they usually heat up and melt the plastic body . Other issues may be tarnished connectors . You can replace the fuse , but use a brand name fuse such as Narva . Ultimately , you must remove this from the cabling and replace it with a proper fuse box or circuit breaker .
I ’ M IN FULL SUN BUT MY SOLAR PANELS AREN ’ T CHARGING
It amazes me how many times I see this question in online caravan forums , and the answer is usually simple : the batteries are already fully charged . Solar controllers reduce the amount of charge they provide to the batteries as they get closer to 100 per cent state of charge . If the controller has a display of the wattage , you can see this reduction towards the end of the charge cycle . Once fully charged , the solar controller will feed just enough charge to maintain the batteries .
