How does one tell if the OV was a temporary, non-threatening excursion or if it is the result of something serious? Resetting the breaker seems risky. Dave's comment about being able to isolate the field field when ship's power is on without the engine makes sense. In that case I wounder if a switch and a fuse would be better. Pulling breakers seems a bit kludgy.

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. Ron Burnett May you have the Lord's blessings today!

By me. Somehow I manage to check "Breakers In" but "Alternator On" occasionally escapes me. And for as infrequently as I use the breaker as a switch, it works fine for me. FWIW, my field comes on with the master, through the field breaker. --Dave On Sun, Aug 13, 2017 at 8:00 AM, kearney wrote: > > Charlie > > Your comment on the OV nuisance trip is interesting.
