Hi all, I'm looking for a 12v load tester that will pass 12v through a circuit with crocodile clips,

im trying to do a repair on some led car lights from a bmw x3 2011 which has a common soldering fault on the chip. There is a tutorial on YouTube where a guy tested the light first after removing to check whether the repair was viable. I have a amprobe but this only tell me that the circuit is open (weird?) and doesn't pass any voltage through the circuit

BMWs answer is to charge £450 plus vat for two new lights, pretty ridiculous really when I originally expected to have to fork out £2 for two new bulbs.

ive sorted it now, guys, i just skipped the test and went ahead with the repair and it worked, saved me a few hundred pounds anyway. i just re-soldered part of both boards and now both lights are working again! good job aswell as i have to travel to scotland tomorrow with work.

Glad it's sorted. The "load tester" appears to be nothing more than an external 12V power source via croc-clips plus a plastic fork, as seen is use at 6min8s. The external power source appears to be a car battery charger visible on the right of the vehicle load area from 6min38s.

Cheers, but it needs to be able to pass a load though the circuit aswell. For 6.99 I don't think it will be a load tester

I use a cheap multi tester and solder crocodile clips on the prongs. You can use paper clips as an alternative. I'm not very good with it and blew one up on mains voltage as setup wrong. Opps! so go careful.

I may misinterpret the text, but if the circuit is genuinely open then no device is somehow going to magically force voltage around it. Maybe you could reference the YT vid for better understanding of the Q, otherwise you may continue to receive best-intentioned but irrelevant suggestions to obtain an ordinary multimeter.

post the link to the tutorial and we can see what the issue is and make recommendations.

so you mean something like a fluke ? where in a house you can put 2000v through a ring main?
you want to be able to put 12v through the circuit and then test it ?
