Polarity checker for 12 volt Power Pole systems

Description

The Original Polarity Checker - Your Friend when checking polarity of 12 VDC Systems
Don't leave connecting your expensive equipment to chance.
That RIGrunner or similar Power Pole connector system might be connected up to a battery or power supply the wrong way, disaster for your equipment possibly.
This handy tool will indicate the presence of power and most important a green light tells you polarity is OK, while Red says Stop and check.
For less than you can now have very cheap insurance for your very expensive equipment.
Field operations and location operating is fun, but if your cables are damaged, or been used too many times, they may not be as good today as when they were first used. Don't leave this to chance.
Built into a Power Pole pair, the indicator will light green for a good cable, with correct polarity and light red for a cable that has reversed polarity.
Throw these into your go bag, and never w
orry again if your cables are the problem.
