There are many things that you can check to ensure you have high functioning electrical connections. Firstly, a simple tug test will ensure that your connections are properly secured to the terminal to which they’re being attached. Turn off all sources of known power – eg. solar, AC vehicle AUX, removing all jewellery, watches etc, to prevent electrical shorting. Use your thumb and forefinger gently pull the wires from their connected point to ensure a stable connection.  There is no need to “yank” the wires as this does not replicate the real-world scenario.  We are merely trying to replicate vibration during normal use of the RV.  If you find a wire that is relatively easily removed from its connection, you should immediately re-secure properly.

Secondly, if you are using screw terminals ensure that the wire is wrapped around the screw are secured in a clockwise manner as this will be the same direction as tightening the screw and therefore prevent inadvertently loosening.

Thirdly, check that the insulation leading into the connection does not have excessive bare wire exposed which could cause a short or that the insulation outside the wire is not impeding the connection.

Overall, at BMPRO we would recommend as part of the general maintenance of your caravan that you would regularly check the terminal connections between the various components of your system. Just as you check your driving lights or your coupling it is very important from a safety perspective to check these electrical connections to ensure not only you and your family’s safety but also the integrity of your system to reduce the likelihood of an unexpected issue ruining your annual holiday.  Most systems are installed by highly qualified 12V electrical experts, but after you have taken several trips, the road conditions and general use can have an impact on your system so regular checking is advisable.

Safe travels,
