One of my weapons is at zero status thus unable to use it. I cant find anywhere, more like can't remember, where to go to have it repaired. I can't equip it in order to use a weapon repair kit. Hope someone can help.

The Sink Central Intelligence unit can repair your items for a cost, and it has 100 repair.

If you don't have the caps you can always find plenty of materials to make Weapon Repair Kits with. Assuming you have 50 Repair, that is.

Is there a way to use a repair kit on a broken item?, kits work on the equipped item...

Ohh.. yeh I forgot about that... I don't think so :/

i was a bit disappointed thinking i could carry the 712K caps ive made from FNV into OWB only to find out when i started OWB, i had ZERO caps

you either found a bug, or you just forgot them in storage.

probably a bug since all of the holograms also had zero caps as well.
at first i thought this was an intended feature of OWB, not being able to carry anything over from FNV to OWB, including caps.
i managed to complete OWB with whatever i was able to obtain through playing (mostly melee), although it was certainly a challenge.
