B.6 Pull-up Resistor Dip Switch Settings
These dipswitches are located inside the back cover of the IG5 ignition computer. The
dipswitches are arranged to allow pull-up resistors to be switched in to appropriate outputs as
required.
Some factory ignition systems have built in pull-up resistors and will not require the dip
switch pull-ups to be set.
The dip switch pull-ups will be required if using factory ignition modules in conjunction with
the constant charge and falling edge spark.
The following is a list of the switch number versus output :-
1 Aux Out2
2 Aux Out1
3 Ign. Out
4 Aux Out4
5 Aux Out3
6 Tacho Pull-up
7 Bypass
8 Not Used
To turn the pull-up resistor on for a particular output, push the switch into the down position
This is a view as seen from the back of the IG5 ignition computer.
Note: Due to the enormous variety of ignition modules currently available, It
may necessary to have additional pull-up resistors fitted. Consultation with
Haltech may be required.
