11/24 Reassembly continues.

I had to make new supports for the two air controls. The old supports were in the subpanel bulkhead that was removed. I made a little triangular bracket to fit against the new sidepanel that will hopefully be out of the way of my long knees.


















The Dynon manifold pressure sender installs in the engine compartment. The sender looks like an automotive part. It uses weatherpack connectors.

There are little green rubber seals that go around each wire. You are supposed to use a special weatherpack tool to crimp the connectors, but one of my crimpers did a good job on it. The pins have an extra long connector that wraps around the little green rubber seals. Don't drop them as they disappear. I am still missing one.


















Since I am not using the rpm gauge anymore, I don't have to run the long cable from the engine through the firewall to the rpm gauge anymore. However, I need an electrical signal for a source for the Dynon EMS. There are at least two options. Use the wires from the magnetos or install a transducer on the rpm takeoff on the engine. Vans sells a transducer that mounts directly on the rpm takeoff on the engine, but it wouldn't work on mine because of interference from the SD-8 backup alternator. Vans sells a 12 inch extension for it so you can put it in a different location. I got the extension but had a hard time finding a place to mount it as I didn't want to drill more holes in my already cluttered firewall. I ended up attaching it to the engine mount with Adel clamps. I am reconsidering my choice and may change back to driving the Dynon rpm from the magnetos. You have to put a 30K ohm resistor in line with the magneto output to knock the signal down to an acceptable level for the Dynon. This would clean up my engine compartment a little.



















The fuel pressure was also mounted on the engine mount. It uses fast on connectors attach the two wires from the Dynon EMS.


















Since I had removed the 60 amp circuit breaker (on the instrument panel) for the alternator, I had to replace it. Vertical power shows an ANL fuse that mounts between the alternator and the output side of the battery solenoid. I ordered one from http://www.BandC.biz.
We had replaced our 35 amp externally regulated alternator with a Planepower 60 amp internally regulated alternator. We had left our regulator on the firewall shelf. We figured if we were ever out of town and we lost out alternator and could only get an external unit, we could reuse the regulator to get us home. However, its location looked like a good spot for the ANL fuse so I removed it and added it to the pile of discarded parts.


















Here is what the ANL looks like when its connected.


















The next step was to hook up the CHT and EGT sensors to the Dynon EMS harness. The Dynon EMS has a 25 pin lower connector (brown wires in picture below) dedicated to just the CHT and EGT sensors. The harness comes prelabled with the function of each sensor so its a simple matter of matching the color coded wires to the same color wire on the sensors, adding a faston connector and plugging it into the sensor wires.
