    Hi folks and the type of “info” in that link is the very reason I want to post up an information section both here and on my web site.


    There are a lot of errors in the info at that link, and these are errors that someone working in the industry shouldn’t make.


    For instance he states that an older type battery chargers should only be used for a maximum of 48 hours.


    Sorry, these sorts of battery chargers should be constantly monitored and removed from the battery as soon as it is charged.


    These old type chargers are not properly regulated and will just continue to raise the voltage being applied to the battery and can cook and destroy a battery in as little as an hour or so.


    And his reference to putting a switch in the wiring between a battery charger and the battery otherwise “the charger may SINK some of the current whilst turned off and flatten your battery”


    It is an industry standard to leave battery chargers, solar regulators and even DC/DC device, all connected to a battery at all times. They will not discharge the battery, unless the device is actually stuffed in some way.


    Another statement “Many generators have a 12V output which can be used to charge batteries”. The 12V output on a generator is a POWER SUPPLY intended for running things like 12v lighting and the likes. It was never intended for charging batteries.


    Again, he demonstrates his genuine lack of any real knowledge of this industry when he talks about alternator voltages, where he thinks they need to run at 13.8v or the batteries will be damaged.

    Many older vehicles had constant operating voltages of around 14.3v and all you D4 owners, when charging low batteries, you will often see 14.7v, and this can last all day long as you drive, and none of you have cooked any of your batteries.



    As shown above, there is a need for accurate auto electrical info.

    Tim great idea the guide you putting together. You could call it "Power to the People".

    As far as topics, what you have suggested is a great start, what about what wire, connectors, fuses etc to use when installing DIY accessories. When to solder or crimp, what tools do you use for such jobs etc.

    I like your reply to "information" found on the web as per the link above. I'm always hesitant to believe most things I read about including what's written on this forum unless the author states their experience and qualifications to make such statements. I have no problem with people sharing their experiences, that's valuable and entertaining and it's what this forum is about, but readers always need to be cautious accepting the info as gospel.

    Hi Ron and the amount of errors in the info in that link is a shame because the guy has done an excellent job of explaining some of the topics, he just has not got the info right.


    Again, it’s a shame because he has done a very good job of it otherwise.

    i would argue that 80-90% of his content is correct and give people a good idea of what to look for.

    I guess it all about research....comparing articles and making a decision.

    Tim has always given/shared his knowledge what is great but if you don't know him at the end of the day it's just another online document

    Thanks Tim, you've come up with a great idea. I'm keen to see the DMM tutorial. Another thing I'd like to have a better understanding of is, solar regulators. where in the system they perform best and how to select the best type(MPPT?).

    Hi Ranga, here is some basic info about different types of automotive relays.


    This is info I already have available, but if there is more you would like to know about them, just ask.
