M2-ATX 160W Intelligent DC-DC PSU

I believe i blew the 15a resistor on my m2-atx, by connecting the battery to the wrong connection. So i switch it out w/ anothe resistor(spare from car's fuse box). I first hook up the ground, than ignition, and once I try to connect the battery wire, the motherboard light comes out for like half a second and goes off.

Do i need to replace the power supply??

It's hard to tell. What you should do first is test the motherboard. Disconnect the m2 psu and connect a regular PSU that is used for a home (AC to DC). Make sure that the motherboard is not shot.

If you blew the fuse something is likely shorted. Tear everything apart, make sure nothing metal is touching the underside of the M2 or the mobo. Then test with a desktop ATX supply.
