Anyone in Will County have a 200 amp DC meter??

Need to do a quick 30 second test on a vehicle and nobody I know has a meter like this
I would appreciate if anyone would let me use theirs.

Thanks Guys.

Not a meter, I have a 50mV 200A shunt though. The catch is you'd have to hook it inline. Hit me up if you want to borrow it.

What do you use it for?? DO you think it would work to test the glow plug circuit on a diesel pick up?
It's easy to access the relay posts, so no issue adding it inline.

I would appreciate the help testing this damn truck when you have time.

You hook a digital volt meter in parallel with it then hook it in series with your glow plugs. If it reads 50mV that's 200A, and voltage less than that is proportional to the current. E.g. if you have 25mV it's 100A.

Mine's 200A but you get the idea. To make a long story short you're talking about E/I=R or 50mV/200A=0.00025 ohm resistor. I've used this trick before when tracking down current leaks that were draining my battery, I hate the idea of running high current through my Simpson 260 potentially.

Sweet, so my regular meter is all we need to use this thing.
How in the heck didn't I know about these things all these years??
What a dummy.
