Jump Leads ....
Is there a freebie article kicking around on how / what to install wrt an Anderson connection at a convenient point?
The LRM article is out of print on this subject.
I'm just the average dude here..I can figure connection on car (bumper, wherever) and on jump lead... but cannot believe that the car end is 'live' at all times, so there must also be a heavy duty switch.. and so on.
So, what exactly, to do? Question Sold the much modified 110 2.8, in Oz
Brought the 90 home from Switzerland ...

Have a read of this article here published in LRM which covers Andersons and cheap jump leads / booster cables

If you follow the advice in the article, then the Anderson connector will be very well protected and the risk should be minimal.

If you want to fit a heavy duty isolator switch, these are available, but don't fit the cheap ones you see in 'blister packs' in car accessory shops. Something like this would be more suitable:

We fit a 300A inline fuse for protection or exactly as ufferlyoffroad says a decent isolator

Bit of a hijacking but would there be any negative effects if one used dinse connectors instead of Anderson ones ie the individual twist ones on welders, to make a remote connection point? Rhubarb and custard let fly with their secret weapon.

I do not really see any the appropriate connector to suit say 35mm2 cable will fine

Lots of different points to consider

We recommend 35mm2 cable, SB 175 amp continuous rated Anderson connecters and 300 amp crocodile clips.

Is it worth isolating an Anderson SB175 connector mounted on the front of the passenger seat box? Debatable as all you are doing is isolating about 6" of cable at the same height as the battery terminals!

IF the Anderson connector was mounted at the front or rear of the Defender yes it should be isolated.

Electrickery.
Question from a electrically uneducated owner. I see that cables are rated at say 200 amps but sparks fit fuses of a higher rating? Surely the fuse should be rated lower ? Then the fuse would blow before any damage to cables? Am I looking at this too simplistically or am I just confoosed ? I see that winches can draw a high amperage but the cables recommended are below this? Can anyone explain this to a numpty? Thanks.

The fuse is there to protect the system, so the fuse should blow before the cables melt.

So the short answer is your right the fuse should be lower than the cable rating Thumbs Up Russell

Electric cables have different current ratings dependent on many different factors.

There is a continuous current rating, ratings for cables in 'open air' alongside another cable, enclosed in conduit, then there is cycle or boost rating.



To give an example 35mm2 welding cable is rated at 225 amps whereas at 20% cycle over a 5 minute period it is rated at 505 amps.


A genuine Anderson SB175 connector is rated at 175 amps continuous or up to 1,000 amps for about 8 seconds.


Now a winch for instance can be rated at a maximum of say 400-500 amps. To have a cable rated for 400-500 amps continuously you would need cable of CSA say of 95-120 mm2. Now fitting cable of that size apart from cost, weight etc you would also have problems with bend radius of cable.



Winches? If you are doing occasional self recovery winching then cables of 35mm2 are normally fitted. For winch challenge events, those boys use 50 or 70mm2 cable.

Logic being occasional use not likely to get stuck where you need full power of winch, can rest the winch (i.e. winch in short bursts) or better still double line which halves the load on the winch and the current draw, OK doubles time involved.



Challenge winching you will most likely be using full power of the winch, in a single line pull, time of the essence and doing it often. Hence you need the larger size cable.



Hope that makes sense.



Just be careful of some of the claims made on various auction sites. I have seen 800 amp rated jump leads made from 8mm2 cable before now. Compare that with the 20% cycle of 505 amps for 35mm2 cable!


There are also lots of copies of the genuine Anderson connectors using the same sort of coding. Have looked at the actual contacts and they are as rough as a dogs backside compared to the genuine ones. This means point contacts, arcing. pitting etc which is not good news

I found this to be quite a good place for Anderson connectors

Thanks Big Russ and Leeds for the explanations. That's a great help. All becomes clear at last. Bow down Bow down
I'm going to fit Anderson connectors on front of the passenger seat box. Stepping outside my comfort zone or what Rolling Eyes Wish me luck.....

Fitting an Anderson connector to front of seat box?

Two main choices, surface mount on front of the box or bolt it to underside of the front lip so that it sticks out of the front panel.

Advantage of surface mount is that smaller holes are required to be drilled in seat box, second method all the cables stay within the seat box.

Take time in working out your positioning. Check that you can connect the second Anderson connector in, can you close the door when connected. Is closing the door important when connected?


Purist will argue that the connector should be isolated by a switch. Yes you can but what you are isolating is about 6 inches of cable. Inline fuse or not? Standard jump leads are connected battery to battery without an inline fuse. Connecting compressors etc put inline fuse between compressor and Anderson connector.


Get some dust covers to keep contacts clean
