Help! New chain popped. Let me explain please.
So I bought a new KMC Gold 10SL chain for my roadbike. It came with quick links. I didnt see the quicklinks until after the fact so I used my chainbreaker to put the chain togehter. I took a few links out as it was a little too long. Well, about 30 seconds into my test ride, I hit the gas a little and BOOM! It broke. Not sure it broke where I put it together or not. Should I use this chain or what? Put it back and test it again?

It most likely broke at the reused pin. If it wasn't damaged overall, remove the damaged open link and install the master link properly and you should be ok.

The chain will be fine you may lose another link or so depends.Be sure you can see the rivet both sides of the chain link.Beware you can take a really bad fall if your chain breaks, so my advice is bring it to where you bought the chain and let them fit it which they should do for free or very little and watch them do it.

The chain doubtless broke at the pin you reused. The pins on those chains are not intended to be pressed out and back in. The ends are peened over and when you press them out the peened-over parts get sheared off and there is only friction remaining to hold the pins in. As you have found that is not enough. Use the master link as it is intended. You should be able to remove the proper half link (outer plates) at the broken end and close the chain back up with the master link. It should then last its normal service life.

Hopefully you measured the chain generously. If you're lucky the only damaged link is the outer link where it snapped, and you can carefully punch out the other end and replace it with the connector. If you were unlucky, you might need to cut out an extra pair of links before connecting it, which is when not cutting the chain as short as possible comes in handy.
If the chain is now too short, you can splice in an extension - as little as one inner link - using another connector.
