Hi Harold, and it is actually quite common to have the “Low Battery Start Motor” message come up after being camping.
I often have customers phone me after they have been camping for a few days and have found they have a flat cranking battery, even though they have one of my dual battery systems fitted.
They want to know why the cranking battery went flat when the Traxide dual battery isolator is supposed to protect the cranking battery from going flat.
My first question to them is “How did you start the motor?”
They nearly always reply “ By jump starting from the auxiliary battery”. To which I point out that their Traxide isolator has worked in revers. Protecting their auxiliary battery while the cranking battery went flat.
My next question is “ How often did you and your children go to the Disco”
They always reply “Quite a few times, usually to go to the fridge”
Then I point out that they flattened their cranking battery by opening the doors so often.
NOTE, even if you deactivate the Interior lights, every time you open a door, you turn on the Disco’s computers and they stay on for up to 4 minutes each time, using heaps of power.
If you are in a safe location, leave one of the doors open at all times and this will stop the computers from turning on and off.
NOTE leaving the tailgate open does not stop the computers operating each time a door is opened, you must leave one DOOR opened to keep the computers off.
You do not need 20 hours of driving to recharge the battery to stop the Low Battery messages. Just a 30 minute drive will replace most of the energy your computers used to discharge your cranking battery down to where the messages came on.
