Just noticed Supercheap have a set of 200 amp leads for $30 -
mine are ok for the wife's car but I think I'm pushing my luck trying to start a big diesel with em
what's the go?
Are they good enough - any recommendations?

I made
mine from welding cable from a metal merchant.
They are long enough to go right across two vehicles so I could pull up beside anything and reach the battery.
Crimped and soldered the ends onto the clamps and after 13 years they will still start a diesel.
Also soldered a antispike thingy across the clamps at one end so as to be able to use them on computer controlled cars.
Cost $15 for cable $19 for antispike A couple of hours to make them.
Made that first night taxi driving for two jump starts.

G'day all, any & every lead needs to be soldered for maximum transfer irrespective of lead amperage, usually by soldering will nearly double amp transfer rate to what they state, if the crimp join is hotter than the cable - that's why they need soldering! maximum transfer, like your garden hose, green hose not much can get through, fire brigade hose lot's can get through, size does matter! Heavier cables rule. I've had
mine 35years, they don't wear out - ever. You get what you pay for, you don't pay much - you don't get much, buy quality first time,
Mine I made from welding cable, soldered, good clamps, regards, aussiedingo

The go is .... don't waste your money, plus they'll be chinese crap.
Get nothing less than 400 amp, heavier if you see them ,
Also a little hint for those with dual systems, if the start battery won't turn the motor just connect the 2 positives using 1 lead only, you do not need the negitive , that should start the engine, I have both my leads cut down to 800mm long

Chinese crap was what I was wary of in the web-link on reply no.5
800 amp but......dunno????????
Good idea linking the batteries with one cable - I should've thought of that but sometimes you just get a bit flustered. It would've probably worked.

You can of course put the lttle button on the dash and do it without moving.
Or if you are as lazy as me put a relay in so that when the key turns to '"start"it links both batteries to start the vehicle.

If you are just doing a quick jump start and there is no underlying engine problem then they will do fine. If you need to crank & crank & ... then get somthing more substantial. As previously mentioned it would pay to
check the crimp conections to see that they are good & tight, you do not need to solder if they are good connections (crimping if done right is a far better job).
Most people don't understand that the cable size is not really the problem, it's the duty time and getting rid of excess heat that kills the cable.
