Hey Boathealer,

The only challenge, I think, to a one-at-a-time test is that the senders for dual station setups normally have half the resistance of the single station senders so that when two gauges, one per station, are paralleled cutting the resistance on the gauge side in half, the ratio between gauge-side resistance and sender-side resistance stays balanced for the voltage divider to work the same way.

So, I'd expect each gauge to be compressed to half the range and maybe not be able to read full port by a hair.
