positive and ground wire.

Did most everyone run two 2awg wire from the battery up to front both for pos and neg. or did most just run the positive and ground battery at battery tray. Just curious if I need to run two big wires up to front.

I have never run a ground wire to the front. Always grounded by battery tray.

But I've always done it. And I single point ground everything to the forest of tabs on the firewall. I have no noise in any of my electrical systems, which I am kind of picky about. So I don't know if they would have been just as quiet without having run it.

Local ground only.

Both batteries.

I fall into the same camp as Vic. I spent a fair amount of time in Nashville as an audio engineer. So by default, I'm kind of anal when it comes to grounding.

I ran two fat wires and grounded everything to the forest of tabs. I don't have any electrical noise.

I think this is a dialogue like the primer wars. Both ways works just fine.

Local grounded everything. Used #2 ga. Sanded paint off of engine mount to firewall interface and applied dielectric grease at installation. Two bonding straps from engine to mount. My starter has pulled 438 Amps from my PC925L without a problem for over two years.

Thanks guys. It sounds both ways would work. heard something about if the ground wasn't as long as the positive wire it could cause some effect because the loop would be different. Did most of you quys use the vans wiring kit or do it yourself. Just trying to figure all the electrical out and what all I need. Sure would be easier if I was an airplane mechanic and not just a pilot. Feel like I'm wondering around in the fog.
Vans says these things are from first page to last a flying bird but I'm starting to see a different picture. I am glad all you guys are here. Thanks

I grounded locally, but all avionics are on a single point ground buss. I have no noise, not on intercom, CD player, xm radio, etc.

Not claiming to be an electrical guru just another point of reference.
I used Vans Electrical installation kit and schematic,heavily modified to suit my needs.
Although I did use a forest of ground tabs for a clean and orderly installation, grounds that are not from the instrument panel are grounded locally.
Audio is crisp and clean and there is no noise whatsoever.

If you have it local look it 2ga welding wire, its much more flexible than the standard 2ga wire. Cheaper as well, I believe I was able to get it for 1$ a foot at the local welding shop.
