Sold Wrong DC Inboard

Hi, I just purchased a new DC Inboard because mine was loose in the area where the adapter plugs in. The seller sent me the wrong part giving me Part #A1095 instead of part #1046.

After changing a couple of the cables around we were able to get it all connected however it doesn't work. This was my main computer so I know it worked just fine when I was able to charge my battery on a friends computer.

Right now it charges the battery, but just makes a whirring sound like a car does when the battery is low. No chime or anything else.

My question is after I return the board should I try to find the right part or does it sound like something else is now wrong with my baby?

Thank you!
