Posted: Sun Aug 13, 2017 1:23 pm Post subject: Grounding RV |
|
|
My RV-6A operated 2 plus years with a Subaru and my forest of tabs bolted to the stainless firewall with the two thru bolts and nuts inside. I have two grounds to the engine from the bolt head and one to each of dual oddessy bats. Had another ground on the panel side of the glove box attached with metal screws and a #8 wire ground from there to the firewall forest.
Am now going to dual EFII on a Lycoming and it has been recommended to isolate the glove box ground, leave the 8 wire to firewall ground AND to isolate firewall ground and a #8 wire to inside post from battery to avoid any ground loops.
Do both changes have merit, or just isolate the glove box ground? Also have wing lights grounded by lamps.
