Hi all,
Our RV-8 has the resistive type fuel level senders and the standard Vans fuel gauges. They indicate fuel levels just fine. Last weekend I installed a Dynon EMS D10 and hooked up its two (left/right) fuel level wires to the signal line on the Vans fuel gauges (so it is also connected to the fuel level senders as they go into the same signal input). Interestingly enough, as soon as the Dynon is hooked up, the Vans gauges show incorrect (too low) fuel amounts. Dynon support (great support by the way) tells me that parallel hook up may not work since the fuel level input ports on the Dynon have a pull-up resistor effecting the voltage and therefore the fuel level indication in the Vans gauges. Anyone seen or tried the same and come up with a solution?
Thanks,
