G'day, All. My uncle had the misfortune to watch his Rodeo go up in flames a couple of years ago.
Fortunately, he was able to acquire an 06-07 GU TD42 ute which already had a canopy and duel battery system installed.
He runs a 60 litre Engel which is great when he goes away, for 6 months of the year, but the battery seems to run down quickly in the off season.
I had a look under the bonnet and found that the second battery is only charged via a solenoid, so there is not much of a circuit that will cause leakage.
My question is this, what would be the best way of maintaining the battery?
