Tracy,
I would like to check on some EC-2 specs, before I layout my
wiring harnesses this weekend. Some of the wire sizes sound too small to me
(like 22 ga for the power circuit on the ignition coils.) They may be able to
handle the amperage, but I am concerned about the voltage drops. I have a
canard so my runs are much longer than say an RV. So that I can calculate wire
size could you supply the following:
1. What is the max current the controller can draw?
1/4 amp.
2. What is the minimum operating voltage of the EC-2?
about 7 volts.
3. The terminal assignment sheet lists both 32 and 33 as
Controller Power Connections. Are these power connections internally separated
(i.e. 32 supplies circuit A, 33 supplies circuit B) or are they internally
connected?
Tied together internally.
4. What is the max current draw on each ignition coil (not
the trigger circuit.)
If they saturate they can draw as much as 8 amps
each. Normally they do not saturate so average current is much lower.
5. What is the max current draw on the injectors and minimum
operating voltage. I have a 40 to 50 foot circuit length and want to make sure
22 ga is big enough.
2 amps. 50 feet? wow.
6. Is the coil disable test switch required? I am using 2
circuits supplying power to the coils, one on the primary coils and one on the
secondary coils. This will allow me to isolate/test the primaries or
secondaries.
That will work fine. You can eliminate the test switch
if you want.
