Welcome back Gibbo - your expertise has been missed!

 

Martin - you're just jealous because you've flounced off twice (that I know of) and no thread appeared either time lamenting you leaving or welcoming you back

 

- glad to see his expertise back as much as the next guy, I've said so on more than one occasion. However the next bit is bollocks BTW.

 

I neither crave having my virtual being back slapped or my virtual ego being massaged nor expect it.

 

Yes Ange I also fully appreciate where I fit in to the forum's credibility/popularity ratings but thanks for the reminder. I also know that if I stopped posting there are a good few on here it would not be miss my input, I actually expect some would celebrate me going, so what?, do you think there would be a huge amount of weeping and wailing if a good number on here left?

 

- some very good people have ceased posting on here over recent months and years and it's never ever been mentioned or even noticed by the majority, aside from the celebratory comments from an expected small number on here I actually would expect exactly the same if I did.

I would agree with Gibbo & Nicknorman. Anyone who works in an industry tends to have general background knowledge and then a lot detailed knowledge about their own working area. In Gibbos absence there has been a lack of detailed knowledge in some specialist areas (e.g. charging and batteries) and that's been the problem.

The legal issue about liability is a good one...

 

It's common for semiconductor supplier to publish reference designs for chips so that you can get them working and them modify the circuit from there. Perhaps it would be worth doing something similar for sub systems such as 240V installations etc. Also an electrical FAQ where specialists can deal with their own area of knowledge.

Greenie!

Now off to buy some quality talcum powder, that blasted squeak just won't stop! It's definately a mechanical squeak, not electrical.

I wonder which category i'm in,''the good,the bad,or the ugly'',must be one of the 'others'. My electric back scrubber must have ruined me chances for an electrical diploma.

Yup....nothing if not predictable....thank-you for proving my point...I'd give you a greenie for doing so too but I've used em all up....

John Orentas and Chris Pink both talk complete shit and both are liable to kill someone sooner or later.

 

 

Have you emerged from a time Machine? John Orentas last posted 18 months ago, and not for a lot longer ago than that on anything electrical.

I think one has to feel slightly chuffed not to have got their name into any of Gibbo's categories, actually!

 

His point is a valid one though, and some of the electrical "advice" given on here has been scary, (avoids use of the word "shocking"!....)

 

I would however make the point it is not just a concern with electrical matters. Some advice around gas installations or even solid fuel installations, (or suspected faults on either), worries me just as much, and also sometimes has the possibility of tragic consequences.

 

Anyway, I've been told I definitely don't need any exhaust for this massive generator I'm installing in the hold, as most of the fumes should make their way out through gaps in the deck boards........ I really must get back to completing the installation, as it needs an earth wire dangling over the side into the water, before it will be completely safe, apparently........

Have a look at your Avatar then take a wild guess.

Oooooh!! That could put you into the Hannibal Lector category,the poor fish.

Hmmm - I was beginning to wonder, then I saw this.

In the first instance it's a bonkers request on the grounds of "? why do it" ; practicality and thirdly design.

Given daft questions it's not surprising that answers go adrift.

 

I don't know whether solutions I have proposed are considered Carp by others, so I'll stop offering them - just in case.

Actually, for me that's a good reason why you should post. I much prefer to see some doubt, uncertainty and caution from my experts.

 

Gibbo is unusual in that he has a vast experience of many differing aspects of battery/alternator powered electrical systems and can demonstrate that when he's in the mood. I trust his advice and also appreciate his frustration in defending his case against self-appointed 'experts' who cannot even imagine the problems he has encountered and plans for. I got a small insight into this from knocking around with Lucas engineers who were starting to incorporate these new-fangled electronic devices into cars in the 1970's. Their experience was that you may think that what comes out of the battery of a running car is DC, in reality it is a much wilder environment than you could possibly imagine!

 

The experts I don't trust are the really confident ones offering odd solutions that cannot demonstrate any credibility

No. It is not taken in the same context as printed press and is 'slander', not libel.

Oh dear!.I could be in bombs of trouble.

[pistnbroke]

Not so bonkers old Goat ..I had exactly that system running in the back of my 4x4 for many trips with a small compressor fridge . Saved on the standby current for the inverter which was good at night when the engine was not running and duty cycle low . The inverter was dedicated to the fridge in fact it was screwed to its rear.

The problems with electrical questions is that the answer has to fit with the readers pre conceived ideas/"prior knowledge" or its regared as "bonkers"

Tell me about it. Designing a one off for your own use is one thing - you'll accept the odd quirk however to do a proper job that meets commercial and legal requirements is a major piece of work.

The one voltage that a 12V car supply isn't is 12V. The ripple and noise on the battery supply has to be seen to be believed. The voltage lift across a body shell (a lot less than boat wiring) means that gnd / 0V aren't where you think they are. Then add in all of the RF interference, transients and the need for good earth bonding. Next add component and build variation, environmental and ageing effects. Don't forget the reverse battery, static discharge, jump starting off a lorry battery etc. It's one of the reasons why devices engineered to correct specs cost so much.

yes chalky I remember the Opus igniton installed on the Jag V12 ..Lucas said install in a cool place ..they did right atop the engine between the banks of the V12 !!!!

Libel is the written or printed word (as on here) and slander is spoken *snip*

 

Read the link. It's slander. In the UK anyway, in the USA libel laws are different.

Isn't here something also about where a site is hosted too? is CWDF hosted here or the US?

It is not always easy to tell as a laymen (I am definitely in that category) who is talking BS or what is expert advice.

 

However, all I can say is that I have received a lot of good information from this forum (Gibbo and others) and I have probably read everything on Gibbo's Smartgauge website. I am therefore grateful for that advice which has led to a much better (safer) DC and AC system on my boat. The BSS inspector commented on how neat and professional the installation was last year. The guidance I received from the forum is a direct factor in the improvements made.
