nope, tech screw into the floor. no star washers or anything, I just cheated wire brushed the area and put in some star washers, lazy I know but it worked.

Hi Guys,
What Tim said about 3lt multi charging is spot on, I have been checking my (via on board screen).
However I disconnected my aux battery, (to confirm faulty crank battery) and stupidly forgot to turn fridge off, (aux down to 11.7v). :(
Dealer replaced crank battery (what a great guy),but with the flat aux reconnected the votage went to 14.7v and stayed there constantly, no variation with motor load,until the battery was recharge (about 4hrs). :confused:
Now every thing back to normal. :cool:
Optima\ Traxide.
Not sure if I,ve helped or hindered. :angel:
Cheers Ken
nope no hinderance there, the info conforms what I suspected, the charging voltage is draw controlled.
if you up the draw from the alternator above the nominal expected load the increased draw will make it think that the battery is low (its the only serious variable in the electric load chart) so the system bumps the voltage up to charge the battery effectively.
Thanks roamer, thats the sort of feedback I’ve got from a few D4 customers.
As long as the neg return is not connected to the cranking battery’s neg terminal, there is no problem recharging auxiliary/house batteries.
With your Optima at that low a voltage when you started, you would have been pulling as much as 60 amps initially.
I’ve measured as high as 68 amps and this is with the Optima with an SoC of 11.5v, mounted in the rear of the wife's D4.
I read where one guy in the UK report that when he measure the current going into his very low Optima, he got a current draw of 97 amps and that’s in a D3.
I was one of the dopes that read this from Collyn, firstly on ExplorOz, then again on the Campertrailer.org Yahoo site:twisted:Quote:

I guess his info wasn't all bad, I did learn not to do it again and he was a bloody knob:MileStone:
I am going to do my own test, I am having a few battery/fridge lasting problems at the moment, so I am going to see what is causing the it, whether it's the battery or batteries, the fridge or the SC40.
Also my EMS1 is reading the voltage wrong from the batteries, according to the EMS1 when I turn the ignition on and leave it for about 1min (without starting the car) the voltage reading is 11.5/6, which sets off the low voltage alarm in the EMS, I then get my volt meter and test the voltage only to find it's actually 12.4 to 12.7 depending on how long the car has been sitting around and that's both batteries(normally the main starter is the lower of the two if sitting overnight or longer.
Any advice would be good if someone has any for this test I'm about to do.

I think the general outcome of this thread, was that the original thread deteriorated into a, let's say less than desirable exchange of ideas. This thread was an attempt to stop it "or else". The result was furthering of discontent, so everyone finally abandoned it.
Seeing as you might have missed some of the previous stuff, consider yourself informed at this stage.
The resulting conclusion is start a new topic, rather than continue to rub salt into the wounds. That said, your point is well taken, I don't have a dog in this race, and decided not to even PM my suggestions for fear of furthering the situation.
Will do:DQuote:

I refer specifically to the following post from Tim Sanderson (Drivesave).
My responses are inset in red (and references in blue)
"Hi rmp, and all that trumpet blowing doesn’t alter the fact that Collyn hasn’t got the foggiest idea about the subject at hand and surprise surprise, I have locked horns with him on many occasions.
One of his favourite lines is that ”Cranking batteries will not be charged above 70% SoC by an alternator” and then he always follows this with the line “As backed by battery manufacturers”.
Sound familiar, and the same thing happens, no matter how many times Collyn is asked to name just one of these battery manufacturers that supposedly back his claim, no response.
He was also caught out on another forum about 12 to 18 months back when a newbie to caravans, posted up a question about how to run his 3 way fridge off his house batteries while camping.
Please provide the reference for the above claim re 'another forum'.
For those not acquainted with this, running a 3 way fridge off house batteries is an absolute NO-NO but Collyn didn’t know this and went into explicit details on how to wire up the guys van and how long he could expect to run his fridge off fully charged house batteries and so on.
This is from someone who is only to happy to tell you how much of an expert he is, yet he went very quiet when a number of caravan owner posted up that Collyn had it wrong.
Running a 3 way fridge off house batteries for more than a short time, like while you fuel up and the likes, will destroy the batteries in no time flat.
The Camper Trailer Book has since about 2006 stated: (re three-way fridges) 'These fridges are intended to be run from the alternator whilst driving, and the auxiliary battery only for short periods - such as lunch stops. They are intended to run on gas or 230 volts ac during all other times.'
Solar That Really Works states 'Three-way fridges run from the vehicle's 12 volt system whilst driving, 230 volts when available, and gas at all other times. They draw far too much energy (10-25 amps) to run from solar'.
Caravan & Motorhome Electrics states: 'Often known as 'three-way' the RV variant usually runs on 12 volts whilst driving and for short roadside stops, and on mains electricity or gas at all other times.
Several articles on my own website confirm the above - some have been there since 2004.
Not only did the self proclaimed expert have no idea of the damage that would have been done to this guys batteries, had the guy not been given the correct advice, but Collyn actually tows a caravan.
I do not own a caravan.
And this is not the first time he has given completely erroneous advice and been corrected.
BTW, he use to post his title in his Signature as being an Automotive Research Documentation Engineer. He don’t post that anymore, not since it was pointed out that in plain english, it mean he was nothing more than a secretary.
This is one of a series of totally fabricated claims made by Mr Sanderson since 2004. At no time have I ever used a signature such as Automotive Research Documentation Engineer.
The claim is legally defamatory and damages my integrity.
I was a Test Engineer with Vauxhall/Bedford at the Chaul End Research Centre and was responsible for the design and construction of a great deal of the testing and measuring equipment used. Textual and photographic evidence for this is at: http://vauxpedianet.uk2sitebuilder.com/vauxhall---chaul-endh-engineering-research-test-centre
Re my background in electronics, it includes being a ground radar engineer in the RAF, design of power system for guided missiles, Application Engineering Manager Natronics Pty Ltd, and then founder and managing editor of Electronics Today International - that I managed to build into the world's largest (with editions in Australia, UK, Holland, Germany, Canada, Indonesia and India. It was awarded the title of the World's best such. https://en.wikipedia.org/wiki/Electronics_Today_International
As I have posted, what is needed is some HONEST INDEPENDENT scrutiny.
I suggest it is indeed so.
Having now shown independent evidence of my background I request that you retract your legally defamatory statements (relating to me on this forum).
An apology would not be out of order.
(I thank Dave for the opportunity to respond).

Hi Collyn and I have no idea what you are trying to prove, raising issues with a 6 year old post and I have no intentions of playing your games.
But be warned, from the first time you threatened to take litigation action against me all those years ago, for what I might add was doing nothing more than posting up the truth, but from that post to this one, I have made a copy of every interaction we have ever had, and that includes copies of threads that no longer exist.
And please note Collyn, these are not links to the those posts, where you may have a new Signature, I have copies of the original posts, showing the signature you were using at the time.
So I do not need to make any statements, I can just post up copies of your own replies to show who is actually telling the truth.
Have a nice day Collyn.
