ecm electrical problem

[palumbogio]

Hello to everyone
I'm new to the forum.

Last week my brother install a new gel mat battery on my wife 2003 Polaris trail boss 330 unfortunately he installed the wire backwards and try to crank the atv than he realized his mistake and inverted the wire the atv started and run for few minute when he realized that a smoke came from the front of the atv the way he describe to me is the electronic control module box before I replace the ecm I would like to know if maybe something also be wrong like fusible link or fuse I'm trying to save 200 + dollars if I can at this time I don't try to start the atv yet to avoid future damage and if anybody as a copy of the wiring diagram of this atv I will be really appreciated so I can check all the wiring.
Thanks in advance for all your help Giovanni
