The following pictures show a custom traction pack monitoring system
that this vehicle's previous owner developed.

It displays traction pack overall voltage, module high - average - and low
voltages, individual module voltages, as well as ambient, front,
middle, and rear traction pack temperatures. The monitor updates
once per second.

A very useful tool for actively monitoring the traction pack, and even
more important in working with older traction packs.
This vehicle's original modules are 20 years of age (c2017).

The monitor is linked via a 3a always-ON fuse to an auxiliary battery circuit
and transmits data in either the key-ON or charger-ON modes.
We have
also added a micro on / off toggle switch
to the dash for easy operation.

A very well conceived and useful modification for the vehicle.
