Police stopped a Pennsylvanian man for driving the wrong way in the West Village early Wednesday — and found a cache of weapons and a suicide note inside his car, sources said.

Victor Greer, 46, was traveling with two AR-15 assault rifles, a shotgun and handgun when cops stopped him for driving northbound on Seventh Avenue near Grove Street around 1 a.m. He was also armed with a gravity knife.

Cops later discovered a suicide note in his car that said Greer wanted to “die in combat,” sources said. It is unclear what he meant.

A box of ammunition and full magazine were also found in the backseat.

Greer was arrested on weapons charges and taken to the precinct for questioning.
