Troubleshooting for Recreational Vehicles

Audio Visual
Suddenly the TV turns off for no reason after watching for a few hours.
The TV turns off when I turn on my LED lights..


Battery not charging
I have driven long distances and my second battery never seems to get to full charge. When I am stopped my Waeco fridge will only run for a few hours and then go into error. Is this a fridge fault?


Cable sizing/Voltage Drop
This section covers a problem that occurs in most RV's cabled by un knowing "experts". It is related to Voltage Drop in cable and problems caused by this.
We would like to know what size cable I would use to connect 4 x 135Wpanels in parallel 12V. What size cable to run to batteries 2.5m distance oneway.


Dual Battery
where is the best place for my battery, under the bonnet or in the back? ... does it make any difference to cable size as well?
we have a mercedes sprinter motor home with two 120 amp house batteries would it be possible to fit a third battery without damaging the charger or alternator


Fridge Problems
I have a gas fridge that we use on DC while driving. It works perfectly until we drive any distance and then when we get to our destination it is defrosted. Can you help?


general 12/24V
Are negative and earth the same thing in low voltage DC? I've noticed the plugs are only two pin verses the 240V AC three pin. Also I know friends who have their dual battery negative running to earth on their chassis. Is this wrong?


Solar Charging
I've heard the most efficient solar set up is with 24V panels and a maximum power point tracker. Is this set up suitable for a caravan? Do I still have 12V coming out of my batteries or is it 24V?
Hi Springers, We are getting a caravan built with a Waeco HDC221 12 volt fridge. We have a 80 series L/cruiser with 2 batteries we also have a Honda 20i generator. What size solar panels etc. would we need to "camp out" for 3-4 days possibly with 2 batteries? Regards, Bruce.
