07 mdx i had to jump the truck to start it i did a timing belt then i jumped it

Jumper cables are making connection to the ‘outside’ of the battery cable clamp.

There is always the possibility of reversed battery polarity while jump starting - which can result in blown fuse(s) . Including the MAIN FUSE... Good luck!
