I've had some minor issues and behaviours that suggest I might have a grounding problem (fluctuating sensor values, EFIS generating an audible hum on my radio). I have two forests of tabs on each side of the firewall, with brass bolts between them. I have braided cables from the negative of the battery to one of these bolts, and another braided cable from the bolt to the engine.
A local builder (of a composite aircraft) suggested I run dedicated ground wires for my avionics directly to the engine, instead of grounding these through the forest of tabs.
Thoughts?
