Adding the External Alternator has been an interesting modification for my RV12 - EAB. With all of the avionics I needed the extra power. After inspecting where the alternator would go, it was identified modifications to the mounting bracket, hose placement, cowling, and cooling shroud would need to be done. Basically the alternator sits on the pilot side and conflicts with the left intake for the scat hose to the cooling shroud .
Started the mods over the last few weekends,
1. Design a modification for the existing alternator bracket. Allowing for clearance with the upper cowl. The bracket is being finalized; we worked by tacking first for placement. I hope to every all install this weekend
2. Prop extension for the 3 blade Sensenich
3. The cowl is approximately ? in longer
4. Modify the cooling Shroud - Relocated the 90 degree intake off the shroud to the left side.
5. Modify the Cowl - Intake mod, cut off the inter lip on the lower cowl and moved it to the left intake.
These pictures are a few days old and are of the ruff fiberglass work. The nice thing is the left side intake will help keep the alternator cool.
I will post more pictures of the finished project once done. I need to thank the guys at KPTW; Al, Ned, Mark, Scott, Dick for their suggestions / help and Bill for fabricating of the mounting brackets
