One always has the tow vehicle's 12 volt battery as temporary back up AND tow vehicle electrical system for temporary load support if necessary.2oldman wrote:
Then that would suffice for a 6v failure also.
Not true, if one of two 6 volt trailer batteries fails one can't load support the remaining 6 volt with a truck's 12 volt electrical system.
Disconnect the link between the 6 volts to get them out of the circuit, then jumper cable from vehicle to ground and +12. You now have the necessary 12 V power to handle the immediate need. Simple.
But, when's the last time you had a battery fail suddenly? I don't doubt that it has happened, but I can't recall hearing of any sudden failures of deep cycle batteries, and it's never happened to me - they die a slow death.
