The picture on the left is the big picture. There are four batteries up front. My contribution to manufacturing so far has been to cut the plywood for the control board. It will reside over the motor. Clearance for contactors, fuses, and the controller should be a lot easier in this rear position. For the first pass, I'm using plywood. once the layout is proven out, I'll probably go with a plastic board, similar to a chopping block.
- two upright on the bottom, tall & narrow
- two sideways on top, flat and wide.
This picture shows how the front box fits in, just behind the AC evaporator. There's still good clearance between the batteries and the ODE shaft where the belt driving the AC Compressor will spin.
Here's where we put the aux pumps. The 12V vacuum pump (replacing manifold vacuum) for the brakes is on the left toward the rear. The Power Steering pump, also 12V, on the right, just over the steering box. It was salvaged off a 2002ish Toyota MR2 and has the reservoir built right onto the pump unit. Additionally, this unit has a speed input so that the boost varies inversely to the speed.
