Hi.
To start with the GOOOOD news...: the engine started today!! What a great feeling to sit in the cockpit and feel the plane ALIVE...!!
It was just sooo ready to go up into the wild blue yonders!
Everything seems to work ok too, except that I had no RPM reading on the AFS 3500.
We've set it up for 4 pulses and we tried 2 pulses, but no RPM.
Setup: Superior IO-360, dual P-mags
The tach signal is taken off the right P-mag and hooked up to the main cable of the 3500, using the white/green wire only.
On the wiring diagram for the 3500, it's also shown a + and a - wire, but it looks to me that they are for a RPM transducer?
So far I've been thinking that the white/green wire is all that is needed...?
Any ideas anyone?
Thanks.
