BatterySystem

Spent some time routing the wires for the two started solenoids from their location next to the batteries to the front cabin. Also connected some ground wiring to the two installation tabs that I will later connect to a ground terminal.

Today the big task was to find locations through the F704 spars to route the fat AWG4 ground wire from the batteries to the firewall. I used someone else's idea for this as Van's approved of these locations. You imagines I deburred the heck out of these holes before putting the grommets in.

One of these holes is used for the ground wire, while the other will be used to route wires from the wing to the panel. Here are some pics of the ground wire routing. I had to drill some 0.5 inch holes near to the batteries and through F705 and F706.

Routed two 10 AWG wires from the batteries to the front of the cabin where the bus master is going to be. One wire is connected to battery 1 and the other to battery 2. Labeled them accordingly. I did decide to buy two firewall pass-thru kits from Safeair1 to get the myriad of cabling (starter wire, sensor wires, ECU wires, etc) from the cabin to the engine department.

Today I connected the batteries with the contactors and routed the positive cable through the bagage area. George Fischer lend me his battery lug crimping tool which makes it pretty easy to make really nice crimps.

I cut some of the welding cable to length to connect the positive battery terminals with the left side of both the contactors and connect the negative battery terminals together.

Last but not least I also fabricated the angles to keep the batteries in their trays. The yellow electrical tape on the side is to make sure there won't be any shorts. The white silicone boots you see in the picture will also help with that.
