hi
help needed
been trying to to get the fuel pump to switch on when ign turned on

could someone please tell me what the parameters should be set at to use pin 2 as a trigger for a bosch 044 pump

im controlling the pump via a SSR

does the pwm pull to ground or send out 5v (need to get my head around this bit)

also this pump is on a non return system so it will be controlled via pressure switch so help with parameters would be great

im totally new to this so any help would be much appreciated

regards
matt

Aux 1 will pull to ground

Haltech give a decent drawing of how to wire things up, although they do omit a flyback diode which would be a sensible idea across the motor

Most of the settings should be fairly self explanatory and just do a bit of testing.
