Capacitive fuel probe "load"

[briangochnauer]

I currently have capacitive probes connected to analog 2" round gauges (left and right) they register between 0-5 volts on one wire.
When I connect (or turn on) the Dynon 180 they drop 1/4 or more. Is there away to run both the analog and Dynon in parallel? Seems the 'load' the dynon is placing on the curcuit is high considering that when I check it with a DVM the gauge doesn't change.

Thanks,
Brian

I have the same setup with resistance fuel senders but you cant run both analog and Dynon at the same time. I have them wired to a switch so if the Dynon should go off line for any reason I can flick the switch to the analog gauges and keep track of the fuel.
