I have an O-360-A1F6D in my RV-4, and it has the Bendix dual magneto. I believe that one side has an impulse coupling, but I can't find out how to determine which side it is?
I assume that the left mag is on the left side of the mag housing, when viewed from the rear. If that is the case, which side has the impulse coupling?
The question comes from me getting ready to replace my panel and wiring. I have an ACS A-510-2 ignition switch. The installation instructions I downloaded from Aircraft Spruce say to place a jumper between the two lugs at position 1 if the left mag has an impulse coupling. Position 1 in the photo below is the two terminals close together at the 1:00 position. As can be seen, a jumper is not there.
So, what does this mean? Can the impulse coupling be on the right mag, and then a jumper is not used? If the impulse coupling is on the left mag, and the jumper is not on the switch, what issues does that cause?
Finally, there is an ACS Ignition Switch Service Bulletin SB92-01 out, and a service kit available, but I cannot find when it was issued and whether my switch falls under the SB. Does anyone know how I can tell?
Thanks in advance for the help,
PS: during the rewiring all terminals will be replaced with proper types, attached using a ratchet crimper...
