I had a case today where someone changed the battery in his van..
He said he carefully made a list if every wire that went to each terminal and thought he put them back the same way..
He mistakenly put one of the wires that should have gone to the Neg terminal to the Pos terminal resulting in a wiring melt down..
Now it isnt rocket science to change a battery ..
BUT PLEASE..
if you do just tie all the wires from each terminal together with a zip tie ..
or..
Spray them with a different coloured paint

Makes you wonder.
Came across this the other day in Wikipedia, very apt.
The DunningKruger effect is a cognitive bias in which unskilled individuals suffer from illusory superiority, mistakenly rating their ability much higher than is accurate. This bias is attributed to a inability of the unskilled to recognize their ineptitude.

Ohhh, I like that. How many people suffer from this and could we start something by accusing someone of suffering from it?
One thing funnier than watching some people back a boat or a caravan is giving them some advice. Boaties in particular suffer from The DunningKruger Effect.

Ha, sometimes spend an entertaining hour or so on a long weekend at the Port Hughes boat ramp, unbelievably crowded, some of the launch/retrieval attempts are hilarious, talk about road rage, have even seen fisticuffs.

Bob - this sort of thing can also be avoided or at least not cause damage if all cables are fused at or as close as possible to the battery. Also if you always use red or brown for positive you can't go wrong...in theory at least!

As some of you know I am away at a CM festival and word soon gets around that I am here and peeps come and ask me to have a look at whatever....
This morning I got asked to look at a solar set up that had been installed by a professional..
The first thing I noticed he had put the 1500/3000w PSW inverter on a shelf where it couldn't get any air circulation and I asked if it gave any problems...yep after it had been running for 10 mins it got hot and the fan cut in then the whole thing cut out and the buzzer went of..
Next he had put a fuse inline on the +ive lead from the regulator to the battery using BLACK wire without even putting a red marker on it..
So poor workmanship isn't limited to the unskilled..

My field is open [bare] mains 415 .. We ALWAYS flash or touch wire even after lamping out !!!
On my old bus I have multy colour sprayed on cables and battery..
Red heat shrink on positive cables..

My Earth leads or negative leads are Red, Green, Black, White, Yellow, And this is all in the same length of wire,
So if I want to fix any thing, I have to trace the wire back to wherever it came from,
I am slowly converting it to Red is Positive and Black is Negative,
It can be difficult, as the wiring is built in and you cant get at it,

Buy some RED heat shrink and put on end of cable..Cover the rest of cable so its not confusing ..

And don't be like a particular "qualified" auto elec that i have worked with and automatically assume that the OEM installed black wire in a harness is negative. Some of the colour codes in modern vehicles is absolutely astounding, with a wide variety of shades and hues being used. It's very hard to tell the difference between some of them too, especially in poor light. Light blues and greens, pale browns, oranges and yellows. Also don't go probing around willy nilly with a test light because replacing a body control module on a modern vehicle can be very expensive if you probe the wrong ones (another "qualified" auto elec did this to the bosses car). Somedays at work can be very entertaining :)

As an electrician I have seen many people try to do their own electrical work, often resulting in disaster. A few weeks ago the coffee lady who visits our current caravan park asked me to fix her machine. The plug top on the machine had 15mm of bare wire (no insulation at all) within the plug, with the movement of connecting and disconnecting the active (which was on the neutral terminal) shorted to earth blowing the RCD and the circuit breaker to the parks sewage pump. Think of the consequences of that. To cut a long story short all the breakers were reset, plug replaced and all is sweet. LESSON 1... Please dont stuff around with electrical stuff, it is DEADLY and can cause fires, burns to humans and DEATH!!!! Get someone who knows what they are doing.

The above seems NO maintenance.. Or wasn't aware how dangerous it was..
Back to connecting 12V at battery.. If EVERYTHING is turned off there should be NO load or or sparks when connecting or more the point no glow on test lamps..

New Zealand, which uses the exact same wiring standards as us, allows DIY wiring without the world coming to an end. The New Zealand government even publishes pamphlets providing help to home owners!
Here is an extract from one such pamphlet:
What are the main electrical repairs you can do yourself at your home?
For a full list of the electrical repairs you can do on your home, please refer to Regulation 64 of the Electricity Safety Regulations 2010.
The work you can do includes:
Replacing switches; socket outlets, lamp holders, ceiling roses, water heater switches, thermostats and elements.
Repairing light fittings.
Moving, repairing or replacing flexible cords that are permanently connected to outlets or ceiling roses.
Disconnecting and reconnecting permanently wired appliances.
Moving switches, sockets and lighting outlets, but only if they are wired with tough plastic-sheathed cables.
Installing, extending, or altering any cables, except the main cables that come from the street to your switchboard.
Fitting plugs, cord extension sockets or appliance connectors to a flexible cord.
Replacing fuse wires and fuse cartridges.

Obviously, that's why more of them come here to live, than us going there.
Although I have heard that the average IQ of both countries decreases every time a Kiwi moves here.

Yep NZ's might be smarter than us[Aust] but Then I have to wonder what their Insurance Policy's are Like..
- I wonder if they have some form of Protection for any issue that cause a Fire after it has been worked on..
Here.. If you do any work on electrics of your own house[If your Not an electrician] I think Most insurance companies will null and void your insurance policy because the work was not done by an electrician..
NZ must have some regulations that covers the general population..
I know that we are not covered..

I would be happy to pay for you to go back again.
Reminds me of the story about the pom who wanted to go back.
The return fare was 200 quid but he found himself 1 quid short.
He approached an Aussie in the street and explained that he was homesick and wanted to go back to mother England but needed a quid for the fare.
The Aussie handed him a twenty and told him to take nineteen of his mates with him.

I had a sparky do some wiring on my coach. He went to replace a 240v power point with a standard house one. When I queried about double pole, he had never heard of it. Quickly got another electrician.
