AC Power Source Select Relay

Written by admin. Posted in Other Details

Here is the finished packaging of the Air Conditioning motor controller, where I happen to be sharing the mounting opportunity for this smaller box that houses the AC select relay.

This turns out to be an ideal location for this function and I had just enough room to clear.  

The inactive port is always electrically disconnected to remove any hazard from exposed metal contacts when the other port that has power coming in.

Dashboard Display System

Written by admin. Posted in Other Details

I installed the Evision display system from MetricMind Inc.

The display shows the important details of the electric drive system. It is programmable and easily changeable on the fly with pre-programmed display assignments controlled by a rotary encoder I embedded into the console storage compartment. I didn’t quite get the color match right on the first cut, but will adjust this at some point.

Auto Torque Balancing Differential

Written by admin. Posted in Other Details

This unit puts the torque to the wheel with the best traction instead of the least traction. It replaces the stock differential. I will transfer the ring gear from the original to this unit.

Most important for 1st gear starts and marginal traction conditions, like snow driving. This will help in the starts of 1/4 mile drags, prevent the inside wheel from spinning in turns and help me get up our hill in the winter snow events. (it happened a few weeks back, needed our 4WD to pull me up the last 1/4 mile) Good for drifting too, in any traction condition.

Interior Control Panel

Best use of an ash tray:

Took advantage of this nice little contained package for my master control panel.

I use it to monitor and control certain things manually while the supervisor processor is being finished up. All this will be fully hands-off when done and possibly re-assigned later.
