Thread: Irrregular behaviour

Hello guys, i got my M4 today and begun istalling it , using my p2140 pri-out as "IGN" and 12v wired to my amp's fusebox , gnd also went to a amp GND.

First thing i noticed was the ZAP sound the wires made when i had connected GND and was going to connect the 12v (NO IGN that is)

Immediatly the led started blinking but i continued connecting the IGN switch aswell.

Sure enough the computer boots..... but when i turn the IGN off .... the psu just continues running, is this because i have all dip's off ?

Another annoying problem is that the p2140 which i've been running for quite some time just decided to invert the Amp-On signal , making the amps turn off when i turn the key and on when i turn off the ignition, any ideas of how to fix ?

Sorrry for my bad english , a bit frustrated at the moment
