  • This talk of alternators failing around 100,000klms has got me interested. I've noticed this winter when I drive in stop start traffic in the CBD with the lights on, I can hear the Surepower VSR kicking in and out a lot more. I should measure the V at the time to see what is going on. Maybe the output V of the alt is down...

    • D4D,

      That's interesting mine sits around its normal charge voltage with just the headlights
      on and the auxiliaries fully charged. Yours must be dropping quite a lot to drop out the VSR either that or the VSR is
      set very high?

      • Yeah it has me interested too Leigh. I might drop by one day and we can take some measurements of yours and mine and try and reproduce the issue.

        • Hi all, in relation to the dual battery set up, is it all 150 series Prado's that have the problem charging the second battery. I have been told, it was only after a certain year when they changed the alternators. I spoke with my local Toyo deal and that had no idea at all. Even their chief mechanic said he had no way of know as both the old alternators and the new "smart" alternators look the same. I have a Dec2010 150 series and thinking of getting the dual battery set up.

          Thanks

          • Hi tactical, being a 2010 you'll be able to install one of LeighW's booster diodes and enjoy the simplicity of a dual batt set-up without the need for a DC Charger.

            Send LeighW an email on here or check out https://www.ebay.com.au/itm/Alternat...AAAOSwsN9XC0gu

            You'll then only need a battery, tray and isolator of your choice and some cable/lugs etc...

            I use a SCI80 from Traxide (Drivesafe on here) which is a little different to most traditional isolators, but the likes of Redarc and Narva and several others also do a pretty good job if it.
            Cheers

            • Hi Guys, I had the diode thing fitted and it boosted charge to 14.3v. It worked for well over a year. Right now, Iím sitting in a caravan park in NSW with a dead alternator. The diode broke in half when I pulled it out. Thankfully, I kept the original 7.5amp fuse. The Lubemobile Mechanic reckons the standard alternator doesnít have the balls to charge a second battery and camper battery. Heís off now getting a new one, (dreading the cost).
              I changed to an SBI 12v 200 amp solenoid too. Iím no sparky but my gut tells me a 130amp alternator wonít be a bad idea. Iíll let you know how it pans out if you like!
              Cheers

              • Dangerduck - Out of interest, which diode did you have?
                You may have just broken it pulling it out as I'd doubt it would get damaged in-situ.

                p.s alternators can and do die, blaming the charging of multiple batteries is a stretch though - think of how many thousands of Toyo's are running 2 or 3 batts for years on end without problems.

                Let us know what you find.
                Cheers

                • G'day, I can't remember what it was. A mate of mine bought one for me when he got his. It went into the Alt 2 fuse slot (replacing the 7.5 amp fuse). Post script to my story above was, the alternator was chock full of dust 'n dirt. When the mechanic showed me it, the clutch was jammed and the rotor shaft wouldn't turn. I had a 130 amp OEX alternator installed for $800.
                  I'm now running 14.1 on both starter and second batteries with the original 7.5 amp fuse in Alt 2.
                  When I got home, I blasted the dead alternator out with compressed air, the amount of crap that came out was incredible. After this, she turned with no problem and the clutch pulley worked again.
                  So I suppose the story here is, I use my 150GX as a 4wd. Running in dusty environments i.e. in convoy, check your alternator from time to time. Giving it a blow out might just save someone $800!

                  • Hey guys,
                    Was told by an auto elec that I needed a DC to DC charger because the alternator switches itself on and off or something so won't charge my 2nd battery properly? Is that true or is he trying to sell me a dc to dc charger...
                    Or will one of the voltage boosters work for fine in mine? Build date May 2012 if that makes a difference
                    Thanks

                    • Hi Rob, the best thing you can do is fit one of LeighW's Voltage boosters and then you will not only be able to quickly charge your auxiliary battery properly but your cranking battery will be maintained in a higher state of charge as well.

                      Don't hold it against the auto elec for trying to sell you a DC/DC device, most of them have no idea how new alternators work, and have been brainwashed by all the deliberately misleading advertising used to sell DC/DC devices.

                        Perfect! Thanks heaps for that info.

                          I've got a late 2013 with dual batteries. There was no need to add a DC to DC charger in mine. I would suggest yours would be the same.

                              Ok, I've been researching now. Thanks. Would the booster fuse be safe to use in my late 2013 150? its a 3.0ltr diesel but the update facelift (droop headlight) model.

                              • You can use a booster in all Prado's up to but not including the new 2.8ltr model.
