BOOST VOLTAGE For $50 Bucks MATE! TOYOTA Prado Hilux Landcruiser FJ cruiser Tacoma tundra 4Runner 

A good ol' trick. The way it works, is that the 'Sense' wire measures the live voltage in the vehicle wiring loom , and the regulator (in the alternator) uses this to adjust its voltage . So if we fool the "s" wire by using a diode in series , it reduces the through-voltage by perhaps .7 volts . This fools the Regulator to set the voltage .7Volts higher. It is just a diode, BUT, is better if you use 2 diodes in paralell ! one going each direction, as the reverse-direction may be needed just-in-case, as some regulators can be damaged using just 1-way. So .. for the DIY guy, it is just a standard 15cent diode from Jaycar, so spend 30cents and a bit of fuse wire between, and its done easy as. If you want to adjust it a bit more accurately, you can also get a diode called a shockley, which has a slight different voltage-drop difference , so you can mix-n-match to get your target voltage.

Had one in my 120 since 2015

Had one in my 120 for about 12 years.

I have an 09 Model SR5 and have not done this modification. I regularly see 14v 14.1v from the alternator in its standard form without this fuse/diode. I have confirmed this voltage with multiple voltage gauges

Only goes up to the 1KD judging by the website, mustn't work with smart alternators I'm guessing on the 1GD

Thanks

Rather use a DC to DC charger, it will charge an auxiliary battery correctly and not overcharge the start battery like the diode method.

Only thing I'd say is I've seen some aftermarket accessories that don't like voltage going higher. I've blown 4 RF modules in two GME UHF CBs. Looks like their radios are not quite as hardened as they claim. Original ECUs etc should be fine as those guys test their gear fully for higher voltages.

perfect!! thank you. 👍👍👍

Pirana's one is bi direction diode so it does not matter which way you put it in.

Great vid. Be interested to hear if many crew have installed in 150 lkd and if works well.

He must have done well out of this video. They are $999 on both of those eBay links😂

Is there an option for the 2.8ltr Prado?

Hey Anthony, does this work on the early 2016 Prado. I see 13.8V into the starter battery & the Redarc then converts that to 14.8 to my auxiliary battery. So, starter battery has always been suffering low input voltage imo.

FYI documentation says Booster can’t be used on 2.8ltr Prado’s or Hilux’s

If you want efficient charging … get a BCDC. So much better

Will this work on a Solara??

You don’t need voltages you need amps. Most phones for example uses 1.66amps to charge at 12volts. Which is a 20w charger, this will charge your phone in roughly an hour. Sure you can charge batteries faster but just have to be careful because a slower charge to a lithium ion battery is better than a faster for long term performance of your battery. Hence why phone manufacturers now have automatic slower charge settings for when your phone’s plugged in overnight called optimized charging. Helps keep your battery in good condition.

Haven't seen these charging ports with the voltage displayed before, anyone know where to buy them? Toyota?

will this fit 2007 hilux sr5?

What’s the benefit to extra volts?🤔
