Wiring ground question

[bwringer]

Better tell Boeing that.

You CAN reliably use a steel frame as a ground for power.

You CANNOT use an aluminum frame as a ground, whether it's a Boeing or a modern Suzuki.

I'm using my frame as ground for my Motogadget rewire, when I get my engine reinstalled I'll run a 6awg ground to there as well.

Would have never thought there may be a problem grounding to an alum. frame, as grounding our GS starters through the alum eng. seems OK. Are the alum. frames possibly a different type alum. than our eng. cases?

Pretty simple: Take your multi meter and read the resistance between the steering head and the area of the battery box.
Steel frames are OK for grounds for an analog on/off switch, but not for anything LIKE a sensor.... like in the voltage regulator
The problem with aluminum is aluminum oxide, which coats ALL aluminum and is a pretty good electrical insulator. Clean the aluminum, QUICKLY make the connection, then paint the connection to keep air away from it. Aluminum is about as good a conductor as copper (for our purposes)... it's the connections that are the problem.

No bud I didn't lol I know it has oil cycling though because I can see it leaking from my *@%^$*@%^$*@%^$*@%^$ty vc gasket so idk it's bout to be tear down season anyway but my real curiosity is about this throttle body electronic fuel injection conversion that people touch on but don't seem to be real clear about in a lot of articles or forms or whatever that I've found anyway cuz I'd really like to just make the bike with the classic look but all modern technology I want to be able to plug it in and play with it and make it do cool stuff
