Went back to connecting up the aircraft electrical power today by fabricating the engine ground wire and the battery ground wire. Both wires are #4 AWG wire with swaged ring attachments. Today I got both wires cut (using a hacksaw) and the ring attachments in place. I'm waiting for rubber boots before final installation.
I also performed the final muffler attachment which consists of 2 hose clamps that run through the two exhaust pipe brackets and around the mufflers to add a little more security to the 4 springs already holding the muffler on.
Lastly, I noticed the spark plug wires were underneath the throttle cable housing when they should be over the housing to keep those wires away from the alternator flywheel at the back of the engine. This involved a complete disassembly of the throttle cable housing to reroute the throttle cables back under the spark plug wires! Sometimes its two steps forward and one step backwards.
Aircraft ground to engine block via #4 AWG wire. I'll probably add a rubber boot to this connection.
Muffler Hose Clamps in place and tightened.
Spark plug and engine wires re-routed over the top of the throttle housing.
