LOL. I'm trying to get you to see what you're missing.
But now I'll tell ya.
It basically redirects all the flow through the ammeter from alternator to the battery.
You will see zero charging on the ammeter.
What's it take to recharge a battery?
If its 5 amps or 30 amps, its all going to take the easy path through your new hefty wire.
Get up to 50, 60 or 100 amps and sure maybe some takes the route through the ammeter because the new path got too crowded.
By then its too late anyway.
