Subject: JabiruEngine-List: Tachometer

Bob, 
While you are on the Jabiru subject regarding the Tachometer, I just re-wired my
alternator coils from parallel to series to get some charging at lower RPM's.
This is an approved change authorized by Jabiru. The Alternator has 2 coil circuits
in parallel and I changed them to a single circuit in series. 
I am using the Dynon DEK-180 for the RPM display. The directions are the same as
for the Garmin which is to set up for 6 pulses per revolution. The tach indicator
has been very steady and accurate for the last 200 plus hours. It is driven
off the alternator / dynamo regulator. It will be another week or two before
I will be able to run the engine. My question is - will changing the wiring
from parallel to series change the number of pulses per revolution. ?? Will it
change to 3 pulses per revolution? 

Thank You for all the help you give to this and your AeroElectric List
