New Ground to Bus

In case of sarcasm, my apologies. A ground loop as it relates to flying a plane is essentially wipe out when you swap ends with a tail wheel airplane when landing. It can be a minor embarrassment all the way to a nasty crash.

I flew a Turbo Beaver floatplane that subsequently (a few years later) was water-looped but fortunately the engine did not ingest water. It was much cheaper to repair as a result. That was a very cool plane. It still is.

A ground loop on landing is an ugly thing!   

Thanks Pete - You nailed my concern about the ground loop.

After reading the article, I now have another question, should I remove the original ground from the busfuse bar, All I did was add in the new ground, now I am wondering if I should have removed the original ground wires which were there, before adding the new ground.

I think I answered my own question   

Here's a semi long read in the link below that would suggest the block is best

And...........the original ground point for the dash is the block when you follow that black wire backwards from the dash.

Seems to me that it doesn't make any difference whether you go to the engine or the battery with your new ground wire.

One way might use a longer wire than the other

One way might be easier to run the wire and attach it.

Sounds like a personal preference type of thing.

Why do you think it's better going to the engine?

Trying to deal with a some Perfectpass issues and one of the things recommended is a good ground. If a ran a new ground from the bus to the motor with 6 gauge wire would that be acceptable? I saw some post which said run a new ground from bus to battery, but I think running directly from bus to engine ground would be better, am I missing something?
Thanks
