Lisle 28800 Digital Test Light with Load Tester

3-30 volts DC dual polarity digital test light
that can also apply load to get an instant voltage drop reading.
Works as a regular test light and when you push the button on
the tool it applies an 800mA load at 12V DC to easily check for
voltage drop on circuits. The display will indicate the voltage
drop when the button is pushed. Displays voltage under load
to tell if circuit has problems like corrosion, resistance, or
faulty connections. 48" cord with heavy-duty alligator clamp for
secure connections. Not computer safe with load applied. Not
for use on airbags.

Cool product but did you say if you see a 3 volt difference when loaded you may have a problem. I'm think if you see anything close to a 1 volt drop you have a problem unless cranking.
With that said I really do like the concept and it is a quick.

I need this in my life. I spend most of my day chasing corroded wiring.

Nice video and tool, i have a question before you press the button does it behave like an led test light? Just wondering what the amp draw is before pressing the button?
