Sure, I understand the importance of fuses when installing 12-volt products in my 4WD, I have always done whatever the installation notes tell me. However, in a moment of haste, I missed one crucial sentence when installing a new brand of voltage sensitive relay (VSR) in my engine bay. I’m just thankful that what eventuated happened in the driveway and not in one of the remote locations I’d just returned home from.
It was one week to go….
Until I left on a four-month adventure. My existing VSR wasn’t working, it was not engaging when the main battery reached 13.4 volts. I reached out to Projecta, one of my sponsors. Thankfully, a VSR200 arrived in my letterbox within a couple of days and I quickly replaced the VSR ‘plug and play’ style.
Over the next 25,000km, I had no issues with my auxiliary battery receiving a charge. Having returned home, the Prado sat quietly in the carport for the next few weeks as I busily got on with writing and submitting travel articles to editors.
One morning I went to start my 4WD, but nothing happened. No ticking from the starter motor, no lights flashing on my dash, just absolute silence. My main battery was flat, thanks to a damaged cell most likely caused by the vibrations from all the corrugations I had driven.
Not to worry, my camper trailer had the same batteries and configurations that were in the Prado. I swapped out the damaged battery but unfortunately, this battery didn’t have the charge left to crank the engine. My 10amp 240volt battery charger was hooked up to the main battery and left to charge overnight. I expected to be able to start the engine without a problem – I was wrong.
Next morning, the battery was still cactus. I contacted the RACV and when the tech arrived, he confirmed that the battery was sick. He was able to jump start me and advised that I should run the vehicle for 45 minutes to let the alternator inject some charge. I ran it for an hour, switched off the engine and held my breath. I turned the key in the ignition. Nothing.
Frustrated, the battery charger was reconnected to the main battery and I went inside to find a replacement battery online. What happened next still haunts me.
I walked out of my office towards my kitchen when I noticed the smell of burning plastic. I glanced out the back door to see black and grey smoke spewing from under my bonnet. I raced out the back door and switched off the charger at the power point. Next, I gingerly raised the bonnet, knowing there was a risk of a backdraft increasing the intensity of the fire. I ripped the alligator clips from the battery and ran to the passenger door of the Prado, tearing the fire extinguisher from the cargo barrier.
A quick shake, pull the pin, then point at the flame and pull the trigger. White foam spewed from the little red extinguisher all over the VSR as it spat sparks and flame. With the flame quickly extinguished and the little red bottle empty, my next task was to stop the fire burning behind the sound deadener under my bonnet. Thankfully my dog’s water bowl was within easy reach and I splashed water over the smouldering area, halting the burning.
What a mess! Foam everywhere, the smell of burnt rubber and plastic, but the danger was still there. The VSR was still sparking as charge flowed from my batteries. I wasted no time in disconnecting the positive and earth cables from both batteries, just to be safe.
It was then the shock set in. What if I hadn’t walked out of my office at that exact moment? What if the bonnet was fully closed? What if the Prado doors were locked? I would have lost my carport and garage; most likely my neighbours’ garage would have been hit hard too. Most of all, what caused the fire?
The Wash Up
It was obvious, with the damage it suffered, that the VSR was the origin of the fire but why? I contacted Projecta and within minutes I was talking to a technician on the phone. After explaining the back story, we concluded that the main battery was most likely the problem.
With at least one dead cell, it was spitting current at the VSR via 4 B&S cables, especially when connected to the battery charger. The VSR is designed to handle 200amps continuous with a peak of 400 amps but it is also designed to have a fuse connected between the main battery and the VSR. This is the one step I had missed in the rush to swap out my old VSR. A big mistake it turns out, but hindsight is an amazing thing. I turned it into a valuable lesson and learnt a lot from it.
I decided to re-evaluate the wiring I had installed throughout the Prado. Now I must say, I have always used the correct size of cables for all my wiring. Old wiring was replaced with new, a new fuse box was installed, old circuit breakers were removed and replaced with 50amp ANS fuses and most important of all, the VSR was replaced with a Projecta IDC25.
Being an automatic 25-amp 3 stage DC/Solar battery charger, I know that my auxiliary battery is now receiving a safe and comprehensive charge. The IDC25 also allows me to have a different type of battery (AGM, WET or Calcium) to the main battery, something I couldn’t do when using a VSR or isolator. I have also installed 50 amp ANS fuses between the main battery and the IDC25 and between the IDC25 and the auxiliary battery.
I was very lucky and had I read Projecta’s installation document correctly, the fire would not have occurred. So, what is all the fuss about fuses? Without them, you are leaving yourself open to disaster.
Don’t waste your hard-earned money travelling on a trip to the Mediterranean – Sun Country on the Murray has it all and more.
The Moira Shire, also known as Sun Country on the Murray, has a Mediterranean climate and 101 sandy beaches to match. Want more? Well, read on and discover for yourself how the region from Echuca to Yarrawonga is the perfect place to enjoy the sun, food, wine and outdoor activities, all within striking distance of Australia’s best river.
The kicker is the Farm Gate Trail put together by a collection of primary producers offering their product directly to you from the farm. Each Farm Gate offers a unique experience and with food crops, grape growers, dairy and even hemp, this region has it all. Regular markets are also a drawcard with the long weekends pulling loads of stalls and people looking for a bargain.
As with any region, I always recommend the first stop to be at one of the four Visitor Information Centres. Here you can discover those special places, new activities and of course find out all about the Farm Gate Trail from the experienced people in the know. I dropped into the Barmah Forest Heritage and Education Centre in Nathalia and was fascinated by the displays, art and of course visitor information.

In readiness for my epic 2018 adventure, I upgraded my suspension with Ironman 4×4 Foam Cell Pro shock absorbers Performance coil springs before installing a MCC 4×4 Accessories steel rear bar with dual wheel carrier. The added weight caused the rear of my Prado to sag and the nose to rise, making the vehicle unsafe on the road due to the headlights being too high. I needed a solution that would be simple to install, have the strength to handle the conditions than I planned to cover, enhance the ride, provide the ability to lower the rear if I removed the wheel carriers and raise the rear when I was packed for a trip.
What an amazing year 2018 has been for me with over thirty thousand kilometres driven, at least ten thousand photographs captured and more than twenty five articles published.
I have explored the best 4WD locations around Melbourne, tackled tracks in the High Country with the legendary Ron Moon and taught a few 4WD newbies a thing or two about how their work vehicles cope in the High Country. I borrowed my father’s campervan and followed the Silo Art Trail in Western Victoria before exploring the Food Trail in the Sun Country along the Murray River. A run along the flowing Darling River was followed by a visit to Sturt National Park and Mutawintji National Park in north-western NSW.
After that, I had little time to prepare my Prado for my epic four-month solo adventure from May to September. I covered over 20,000km through stunning sections of the Northern Territory and Western Australia, some so remote I felt truly alone, others so populated I felt overwhelmed. Deserts, gorges, National Parks, Australia’s Coral Coast, the Pilbara and the Kimberley were all extensively explored, and I was blown away by the beauty of it all. This trip ended with a crossing of the Simpson Desert via the Madigan Line with a great friend of mine and I will always remember the experience we shared covering some of the most outstanding country I have ever driven.
So out of all this, I have come up with my Top 5 Destinations that I visited during 2018. If you haven’t been to any of these places, I suggest you add them to your bucket list for 2019 and beyond. Read More
