So I bought a "new" Kilovac EV200AAANA from Ebay. It's listed as new, the picture shows a new one. Total was ~$45, including about $13 for shipping.

When it arrives, it's clearly used. Scuffed, dirty, no hardware, cut wires.

So I initiated a return, and the seller is offering $10 off instead.

My gut reaction is "no," on principle. But the flip side is I only bought it as a secondary low-side contactor.

Thoughts?

it was likely removed from some piece of equipment, so test it on the bench and determine if the contacts have been damaged or not. If okay, then take the money and keep it;

How would you test the contacts other than basic ohming, and maybe running a few amps through it?

You would need a 4-wire meter to measure the exact sub-ohms of the contacts, but a quick check would be to energize the coil and just measure resistance across the contacts.

If it measured more than 1 Ohm then it might be damaged; if it is good then it will be under 1 ohm in the 0.1 region depending upon your meter.

For diy use it may not be as critical that it be in "perfectly new" condition. i never send anything back if they offer a discount to make it right, but that's just me.

I have a good power supply and a meter, which will do the trick.
