Waeco Trap or Dual Battery Dope..That's me!!!

After annoying you lot the other week about batteries, dual, Calcium, AGM blah blah blah and the fact the house battery seemed to be going flat much to quickly in use, I decided that before spending the dollars replacing batteries, that it would be wise to have a look through the wiring system looking for possible leaks as suggested by some.

However, before I got down and dirty, I isolated both batteries and placed them on charge with one of those el-cheapo jobs - red, orange and green indicator lights -that put out aout 2.5amps contiuous. Interestingly the "Cranking" battery took approx 14 hours to come up to charge according to the green light on the charger but the "House" battery took about 30 hours to show the same.

So where had all the charge gone remembering my truck is only used for camping and sits in the drive doing zip between playtimes with all the gadgets turned off, or so I thought?

So, during the constant checking of the battery charge state which I did pretty regularly up to bed time over the two dfays it took, I noticed on one trip around the back of the truck when I had the carport light turned off in the evening, that a faint glow was visible in the canopy.

Yep - You may have guessed it - It was the internal fridge light on the Waeco 80 litre job which although turned off at the fridge panel, still provided power to the fridge light as I had the lid wedged ajar to air the interior. The power chord I normally leave permanently plugged in via the fuse board in the canopy and it would seem that even with the fridge is turned "off", it will still supply power to the light - trap for old players methinks.

So that, coupled with camping trips of a few hours driving duration and overnighting with all the acc draining away the juice I consider the problem now solved.

I suppose your never to old to learn...........But did save some dollars by not turfing a perfectly good battery after I had finished the Humble Pie.

It's all good now.
