737NG Wing-body overheat on ground

Hi Guys,
I was discussing with an instructor about Wing-body Overheat on ground 737NG.
After you do the Wing-body Overheat NNC you isolated the system(Left side) and the Wing-body Overheat light extinguishes.
But you are still on the ground. If we check MEL ATA 26-12 it talks about the Wing-body Overheat System INOP, I think this checklist is not applicable as the system is working fine and telling you about the overheat Condition.
So is this a go (the light already extinguished because you isolated the problem and we assume single bleed operation on the opposite side) or no-go item ( as there is a possible leak in the bleed duct and should be investigated first by maintenance for any damage caused)
Thanks for your thoughts...
