Grenadier build – Expedition HQ install

The Doc had Expedition HQ, on the Gold Coast, fit the Redarc TowPro Kit, the 13 pin Euro plug was replaced by a 12/7 pin flat pin on its own wiring loom, various Anderson plugs were fitted (5 in total). Two for solar input, 2 for fridges and the last for towing, A CTEK 250SE was mated to the 120S and lastly the Clevershade 270 Awning was fitted. A long day and most of the changes are hidden.

The same Clevershade awning fitted to a LC300.

Grenadier build – UHF install

AERIALS FITTED
The aerial on the left of screen is the RFI CD63 Black 6.5dbi removable aerial. It is very thin, so the driver’s vision is barely impacted. The twists you see 1/2 down the whip is there to absorb vibrations/corrugations. When travelling across corrugations The Doc calls it the hula girl.

This aerial is fitted to a GME TX3520S.

The aerial on right of screen is the RFI CD961-71-75. It has interchangeable antenna whips which operate at 6.5dBi and 3dbi. The 3dbi whip is tiny at about 10cm long. The larger 6.5dBi antenna is fitted in the picture. This aerial is fitted to a GME XRS390C. I have a GME XRS-BT1 hands free kit to install on the GMEXRS390.

The handsets are mounted on the passenger’s side of the centre console, using the Brodit bracket.

The basic cable feed is shown in the second image.

Anderson plug pitfalls

A link to The Doc’s guide on Anderson plugs, commonly used in 12 volt setups in cars for caravan, car fridges, etc. Guide is here with links to the right tools, suppliers and techniques to make great crimps.

Battery Monitor Review 12 month update

The BLE Battery Monitor was reviewed here.

All three BLE battery monitors have now been working for 12 months, monitoring two AGM batteries and now one Lithium battery. All are still working. The original review stands after 12 months.

Parasitic drain

The BLE battery monitor does have a parasitic drain on the battery which cannot be picked up by the Battery Management System on The Doc’s Invicta 125 Ah lithium battery. So the battery can be slowly drained over time with the BMS still showing a 100% charge. It seems the draw of the BLE and the BMS itself are too small for the BMS to monitor.

BLE App being updated

The BLE App has been updated probably three times over the year. Minimal features upgraded, but good it is to see regular maintenance updates.

Lithium battery issues

The BLE is not designed to be used on Lithium batteries, so it does not properly monitor the charge, as a Lithium battery has a different voltage profile to an AGM. The BMS has a Bluetooth module that communicates to the Invicta’s App, giving The Doc all the details about the battery. The BLE allows The Doc to see what happens over 30 days and graphs that data. UPDATE: BLE has released a Lithium version of the battery monitor.

Conclusion

Money well spent.

Automotive 12 volt guides

The Doc has put his 12 volt guides together on Anderson plugs, crimping and fuses. You can go to this page here, or choose Nissan Patrol on the Menu above and go to Automotive 12 volt and the articles will appear on the right side.

12 volt car fuses–buy quality fuses–avoid Cheap Chinese Crap

In short, Cheap Chinese Crap (CCC) blade fuses are unsafe to use.

Just like Anderson plugs, which The Doc discussed here, blade fuses have been overrun by Cheap Chinese Crap. Avoid buying Cheap Chinese Crap, it can be a matter of life and death.

CCC blade fuses are commonly sold on eBay and Amazon. There is a reason why they sell fuses for a few cents each and quality fuses can cost a $1 or more. CCC fuses do not work properly, and they pose a real danger to those who use them. They are unsafe to use.

Fuses, to be safe and effective, need to be built to a specification and certified to perform in accordance with that specification. Cheap Chinese Crap doesn’t. In the case of a catastrophic fuse failure your car can catch fire and be burnt to the ground or you can be injured/killed or have your expensive equipment destroyed. While catastrophic failures are rare, you do not want to be the unlucky one, when it can be avoided.

Saving a few dollars buying CCC fuses is not worth it. If a CCC fuse damages a car’s wiring loom, the repair bill can run into 1,000s of dollars.

Problems created by CCC fuses

Poorly made fuses can have one of more of the following problems:

  1. incorrect manufacturing tolerances, so the fuse does not fit properly in the fuse holder. Poor contacts can mean your device will not work or it create shorts, and in worse cases scenarios fires;
  2. not meeting the rated performance specification. For example, a fuse rated at 5 amps does not blow until 12.5 amps; way beyond the specification, risking fire and damage/destruction of the device the fuse is supposed to protect. Here is an eye opening video, where CCC fuses do not work as rated: https://youtu.be/bVKuYOA3F2E
  3. use of inferior materials, meaning the CCC fuses may melt and catch fire. Another eye opening video here were CCC fuses, when they blow, often melt the plastic fuse cover: https://youtu.be/tDuJx1qciBg

Both videos show how dangerous these CCC fuses can be. Minimise your risks, avoid Cheap Chinese Crap.

What to buy

Buy fuses which are certified to perform to specification and have a rating marked in white on the back of the fuse (5, 7.5, 10, 15, 20 amps, etc). So only buy fuses with the white rating from a reliable dealer. Do not use fuses which do not have the rating painted in white. All the fuses in The Doc’s car have these rated the fuses from factory. Car makers understand the importance of rated fuses and use high quality fuses when making the car. You should do the same.

Quality rated fuses are made by LittleFuse, PEC, Jeng Feng (Taiwan), Bussmann (who source from PEC and JF) or Prolec. The Doc buys his fuses online from Swe-Check, a fuse specialist. Quality fuses normally come with a specification sheet.

The Doc was not always so informed and has wasted money on CCC fuses (now happily thrown in the garbage, with a lesson learned). This post is to stop you making the same mistake. While this post concerns blade fuses in cars, the main points apply to other CCC fuses. Avoid them.

Tip: all components in a car’s 12 volt electrical system should be good quality, Australian made copper wire, tin-plated copper (not brass) crimp terminals, genuine Anderson plugs (not Anderson style plugs), quality certified fuses (not CCC), etc.
