Thread: Jump start points outside battery box

I agree with Wally, a 50amp might be OK for a simple jump start where it’s just a bump of the key.....

There are times where you may need to turn the engine over for longer than four seconds.....either yours or the other car. This maybe be pushing the the limits of 50amp plug....and or the wife need to use the set up and isn’t across limiting how long you hang onto the starter.

Our work cars have 175amp Anderson and seem to work without issue, it’s what I would fit to the defender if I ever decided to carry jumper lead.

While your work vehicle may not have any issues, have you ever heard of anyone having issues because they used a 50 amp Anderson plug setup for jump starting.

I have carried out numerous jump starts with a 50 amp Anderson setup, both as the donor, and as the recipient, and know of many others who have done the same, and not a single issue.

Just because people "THINK" there might be issues does not alter the fact that they are doing nothing more than inventing a problem that evidence shows, that a problem does not exist.

Again, I have never heard of anyone having a problem when using a 50 amp Anderson plug setup for jump starting.

For something that takes maintenance out of the equation,, quite resonable I reckon...

Never seen anybody using 50amp Anderson in jumper leads....therefore cannot compare.

Have done plenty with 175amp without issue......most people follow what’s worked for them or provided for them, I don’t decide (well I kinda do with mine) how our work cars are fitted out.....

I think most of us understand from your posts/experience/knowledge that 50amp Anderson’s will do the job.......not sure why you are getting so worked up over others going over and above.....I’m sure plenty of members will follow your advice

I probably should give it a go as I use 50amp Anderson’s on everything 12v regardless of cable size or current draw and I probably have a 5 or 10m piece of 6B&S with 50amp Anderson’s fitted.......but to date I’ve never carried jumper leads.

On a side note I do have a question about your headlight/driving light kit for defenders as I need to grab a kit for my current ride.

There are two kinds of jump starts. One is where your engine and battery are in good health, just that your battery has been accidentally discharged to a low state. For that kind a 50 amp connector and a little time to transfer charge to the flat battery is all you need.

Then there's the other kind, where something serious has happened and a fair bit of cranking energy is needed. It might be that your diesel engine has lost its prime due to running out of fuel. I wouldn't like to try this with fiddly little leads on a 50 amp connector.

Hi Weeds, it’s not about getting worked up, it’s about saving people buckets of money if they are lead into “THINKING” there is going to be a problem when no problem exists.

In the case of your own reply, you stated your work vehicles were fitted with 175 amp Anderson plug. A good observation!.

Then you went on to make out there could be a problem, without ever seeing such a problem.

We could all ponder the what ifs but it’s the here and now that is relevant.

When my RR did it’s alternator, there was a 155 amp discharge load being caused by the alternator.

I had to get enough power into the RR to be able to start the motor and move it off the middle of the road.

I not only got the motor started using a jumper lead with 50 amp Anderson plugs, I was able to run the motor for a little over a minute before the 60 amp in-line circuit breaker finally tripped.

Thats loads way in excess of what is needed for any jump start. And a hell of a lot longer than 4 seconds.

In this situation, as I had far more pressing things to do, I did not check to see how warm/hot the Anderson plugs were, but they did the job.



As for the Headlight Kit, can you hang off for a while.

I just managed to get enough relays in before Christmas, to cover the orders I had.

The importer told me they have 1,600 on back order but they have not arrived in the country yet.

There is a substitute, but they are crap, and I will not use them AGAIN.

Got burnt the last time I did.

My comments were based on the manufacturers rating that you posted....I can only assume it not ideal exceeding them....with 175 or 350’s in some situation might keep you inside manufacturers specs.

If I was in the middle of a mine site l...before reading this thread....and was presented a situation of a car fitted with a much lower rated Anderson plug than yes I might suspect something based on knowledge at hand....have only used 175 to date

how many times would two cars fitted with identical Anderson plugs be side by side....hence why most seem to carry a set of clamps fitted to an Anderson........plenty of things can go wrong when using the clamps on one end......

Either way I’ve never been caught with a flat battery when touring...I don’t carry a jumpstart park or jumper leads.......and doubt I will in the future.

Just passing on my workplace experiences and it’s minimum requirements.

For many years I have been fitting a Anderson plug on the front of Defenders with a isolator switch on the passenger seat box.
Fitting to the front of the vehicle, in general makes it very easy to get up close to the other vehicle with no opening of doors etc etc.

The isolator switch does two things:
*Prevents some monkey from tampering with the outlet.
*Lets owners connect jumper leads to the stranded vehicle without fear of touching live bits to where they shouldnt touch.

*I use the big Anderson plug simple as you can get a Anderson plug handle that attaches to the plug (on the jumper leads) making plug in and out simple/easy.
