First of all, have I mentioned it is hot outside?

Since Dan Checkoway always includes funny pictures of his cats in and around the airplane, I thought I'd include a picture of my cat trying his best to stay cool on a hot afternoon... either that or he's hoping I'll drive away and end the misery.

Here's a shot of the upper front fuselage giving you a better idea of how everything fits together.  Click the photo for a larger version.

I'm running wire up from the floor through a piece of 3/4" conduit.  It then travels along under the rib and swings up from under the sub-panel to the ExpBus.

Here's a shot from the other side.

I installed a second continuous-duty solenoid and an ANL current limiter base directly under the master solenoid.  This will enable a complete alternator cutoff in case of a runaway over-voltage situation.

I also ran the starter cable from the black starter solenoid, finally deciding to route it under the cylinders instead of around the outside.

A copper bar down the center will join the three solenoids together. (temporary aluminum template seen in photo)

The starter wire continues along the side of the oil pan and attaches to the engine case with an adel clamp.

It then turns toward the starter, secured again by another clamp under the alternator mount bolt.

Here's a shot of my solenoid arrangement with everything done except the final attachment of the alternator B lead.

Master at top, starter on right, and Alternator on the bottom.

I have a solenoid for the internally regulated alternator so that it will be completely disconnected if the field is cut (either by the overvoltage protection or flipping the switch).

The ANL current limiter will protect against excess current (not over voltage).

Copper bus bar is used to conect the solenoids and in places where it would be difficult to get a fat wire in there.

UPDATE - At 100 hrs, my voltage regulator died on my externally regulated alternator. (I switched to an ext regulated alt before first flight)  I rewired this area and moved the VR to the firewall. 

(updated picture below)

Back to aft of the firewall, the panel wiring is nearly complete.

I installed a solid state dimmer controller just behind the subpanel using a couple of pop rivets.

This one controls the two cabin eyeball lights, and I'll put in another one for the glare shield lighting.

I removed the panel so I could paint it.  This photo looks worse than it really is.  You just have to remove the ExpBus, control cables, and a few other things to remove the panel.

 

And here is the panel after it was painted.  I'll have all the labels silk-screened on and then will finish with a coat of matte clear coat before I reinstall it.

I think I achieved my goal of no big round holes in the panel!  Plenty of room left for backup instruments later though.

While we're looking at the panel, here is a closeup of the mapbox door.  I riveted the hinge so I could remove the pin.  I also cut the door so it would mount flush inside the frame.  I installed a magnetic latch to hold the door without the need for a knob on the door.
 

(Sorry about the fuzzy picture)

A push on the closed door will release the latch.

The ELT was installed just forward of the flap tube on the co-pilot side.  I made a new antenna cable and routed it behind the flap access panel. (not shown).

The antenna base is mounted just aft of the roll bar.

It is held in place behind the roll bar by plastic clamps and a pop rivet..
