I reworked the stock instrument cluster by creating new artwork with a drawing software tool called Visio and printed it on plain paper with an HP Laserjet 8500. The backside of the paper was printed with a colored mask to mimick the factory design. When the dials are backlit at night, the white lettering and graticules appear aqua. It doesn't look exactly like the factory dials but it's close! Note the icons I made for the motor and traction pack.The meter movements are driven with custom interface circuitry which uses an optical isolation amplifier IC so that the traction pack remains isolated from the signals entering the passenger compartment. Also, since the meter movements have the accessory battery voltage connected to them, the isolation amp keeps the traction pack isolated from the accessory battery.
I didn't care much for the round look of the Emeter in the presence of the more rectangular factory ICE instrumentation. To overcome this, I used a 1/2" thick piece of textured ABS and counter-bored the backside to accept the round emeter housing and cut a rectangular opening with beveled edges to "frame" it's display and buttons. Now, it fits in much better with the rest of the design.
Here's what everything looks like after installed in the dash board. The meters are pegged because the interface circuits aren't designed and built yet. There's always something that isn't finished!
