With a little bit of understanding of automotive electrical systems this tool can save you a lot of time in diagnosing problems with relays and circuits

I was waiting aeswave tester to be available, but this one more than half price $85 , and same job:1- activate circuit and components2- 6 adapter pluse universal adapter with pin numbers on wires very easy to hook up.3- only difference is there is no external wire to measure the amp through the circuit just like uactivate tester, but if you are an electrician you know how to test amp through the test terminal on the tester.I have ancel power probe circuit tester but use this one for relays and got relay tester also for 22 $, one year warranty and u.s based company, thank you cal van

To bulky to plug into some fuse boxes. Could be slimmed down.

this is a real-time saver if your working with relay-controlled circuits. lets you easy see if a relay has the voltages to be closed / open and also lets you manually close / open contacts for testing.

It proved I had expanded the fuel pump relay contacts during testing of the circuits. It was on a 2009 Kia Sportage under hood fuse/relay box. Car would just shut down when temp was high. Relay circuit tool proved my theory. $299 later for a new fuse box corrected the problem. Having this tool would have prevented this situation in the first place.

Adapters are slightly (1/8 to 3/16") larger than the relay being tested. In power distribution boxes with closely stacked relays the adapters do not fit. Limited usage.

Warnings do not buy this is junk bought back in January and just now using it. Tried jumping the relay no power to pin 30 very disappointed, if I could return it I would waited to long. Don't waste your money

This is a great test kit that cuts through a lot of the headache of testing relay circuits.
