Either consular or scout have repair in your natural skill talents in K1.
Mind you that you also need to have at least a 13 repair and to find all items in the game that boost the repair skill. I believe the magic total number to unlock all features is 17. A pair of gloves, a belt and a head piece IIRC.
Sorry, but I do not believe your character alone can do it as-is.
However I do know a trick (maybe it's a bug in K1 for my system
) if you talk to HK-47 as an NPC teammate (Zaalbar or T3) with a high enough repair skill (HK-47 AND said "talented member" obviously must
be in your party at the same time and it must be outside
the Ebon Hawk), it automatically switches to the main player character. HOWEVER, you will have the skill stats of the NPC teammate you first used to engage HK-47.
So as, say, T3 you have a 20 repair for example... As T3-M4 you go up to HK-47, and engage. It switches over to your main Player Character for dialog. Attempt repair, machine check shows your current skill is 20. That should do the trick. I think the patch "fixes" this little bug unfortunately.
This also works for other instances, just can't recall what those are since I haven't played K1 in a long time.
Hope that helps.
