iii) No Idle Valve: (MS1 and MS2)
a) Solder components Q4, Q20 and R39 in place. Note, this gives you a programmable output
that can drive a relay e.g. cooling fan on FIdle (Pin 30 of the db37)
26)
Trigger input:
Remember you have already decided between VR, Hall or coil –ve. Note, Hall input
covers all inputs like VAST, EDIS PIP, GM HEI, etc.
See the specific manual for you’re engine's input to find out if it’s 5V or 12V. If in doubt measure the voltage
with the engine stopped and ignition on.
Hall sensors Only (EDIS, VAST, luminition, etc):
a) Link OPTOOUT to TSEL
b) Solder a wire between TACHSELECT and XG1
c) For 5V inputs fit a 470R resistor into the position of R12
d) For 5V inputs solder a wire between the top hole of C30 and 5V on the proto area.
