Assaulting the batteries

Armed with an (insert sponsor's name here)* battery tray, a (insert sponsor's name here)* 4WD battery, a (insert, blah blah blah)*150 amp isolator and a couple of miles of loom tube, I set out to make our troopy (almost) proof against getting a flat battery in the Simpson Desert - and to get high wattage power into the back.



The tray just fitted between the existing battery and the scary octopus of high-tech electrics that comes out of the passenger's fire-wall.



Interestingly the tray uses one of the captive nuts on the mudguard - unfortunately the same one I'll need for the relay on the bull bar indicator harness when I put that in. But I guess it's OK to use the same bolt for the tray and the relay.



Finding a spot for the isolator wasn't quite as easy. Every place I tried was either too near the exhaust, too narrow or too far away. I finally settled on wedging it between the second battery and the mudguard - using the little mounting bracket that comes with it. The bracket isn't exactly sturdy (OK so maybe don't insert sponsor's name here) so I've gunked it up with liquid nails before assembling it onto the bracket to minimise it flapping around. Hopefully the solid state electrics won't mind a bit of movement.



Then it was a just a matter of getting some heavy cable from the boys at Battery World (oops, I mean insert sponsor's name etc etc) and putting it through one of the complex grommets that Toyota had helpfully put in the firewall. Or at least it would have been simple if I hadn't installed a huge battery right where you need to put your hand to get things in and out of the firewall grommet. Lubricating the cable and tapering it down to only one of two wires made it a lot easier to get it started - then you could get a grip and pull it through - being careful not to rip the whole assembly out of the firewall!



The cable then runs along the passernger's door sill and then inside the left hand wall to the rear of the truck. It's all wrapped in loom-tube and cable-tied so it doesn't rub too hard on any fire-inducing metal bits.



Wired up our 40 year old Engel and it worked - amazing!



So we're just about organised enough to tackle the Flinder's ranges and Cameron's Corner. Should leave tomorrow - assumingwe get organised.

Slicing off the roof and cutting up the countryside

Well after 3 weeks without our Troopy we now have a roof bed and awning. Off down to the Toyota 4wheel drive car club property near Bungonia to try it out. We were very snug at 0.1'. Sat morning up early to start training - one to do the driver training and the other recovery and vice versa on Sunday. Oh my god driver training was terrifying for me (in John's new pride and joy) but with 10 instructors shouting and waving arms through the windows and over the CB it was hard to cop out - I was first in a line of 12 cars so impossible to turn around and go back! Sometimes my legs were shaking so much I could hardly press the peddles. We weren't allowed to use the diff locks because that would be cheating! Most tracks appeared to be vertical and some had cavernous pot holes which meant there were often two wheels off the ground.

Recovery was fun but made us realise how much equipment we should carry and how dangerous it could be. I think it made us realise we need to go with experienced people for a while to learn some more tricks.

assault of the batteries - TLCC

Well today I spoke to the folks at Christie Engineering who pointed out that although their beaut little 12V generator was the fastest thing around, it wouldn't charge a deep cycle battery very quickly because once the big lead plates in the battery built up a surface charge, they would not take much more charge quickly - and the charge rate would fall to a trickle. Better to use a cranking battery with lots of little plates, or a hybrid one that is the best (or maybe worst) of both worlds. So still thinking about what sort to get.

Meanwhile, we went to the Toyota Landcruiser Car Club - TLCC - for the first evening of their introduction to 4WDriving course. Instructors Simon and Bill did a good job of setting ut the basics of driving techniques, 4WD toys and most importantly safety aroud the two day practical course being held this weekend at one of their two properties near Tarago.

And oh so exciting, we pick up our chopped troopy from the boys at Trakka tomorrow, with its new hinged pop-up roof and bed-in-the-ceiling; a landcruiser with an upstairs.

bright sparks in the bush - remote area power

Well the troopy's still getting its roof done, but meanwhile I've been busy confusing myself about how to run the fridge when you are parked in the one spot for days. The options seem to be solar, various generators or just run the engine for a while each day.

Solar is nice for the planet and works virtually indefinitely, but it's slow. If the panels are fixed onto your roof, you have to park in the sun which kind of heats up the fridge and rather defeats the purpose. If you use portable cells then you have to stay with them so they don't walk off with someone else. They seem to need just about the whole day to make much difference to an 80 amp hour deep cycle battery, so that limits your fishing time just a bit!

Generators are notorious around campsites and a great way to really annoy your new neighbours, but the newer ones are fairly quite and seem to be a lot quicker than solar. You get rather more fishing time, but have to carry extra fuel and they aren't very nice for the planet.

The best one I've seen so far is a 50 amp alternator running off a little 4 stroke engine. It's made by Christie Engineering (02 9620 1208 enquiries@christieengineering.com.au) and looks like this http://piranhaoffroad.com.au/index.php/default/obc25-55-amp.html .

Probably the only thing worse than running your generator out the back of your tent is running your huge turbo diesel tropy engine under the noses of your camping neighbours. So every approach has its ups and downs and maybe it's a matter of choosing your preferred poison and sticking with it.

Speaking of which, is that sun over the yard arm yet? all this typing is making me thirsty....
