Wolfgang, the 'shunt' is nothing more than a direct connection across the amp gauge terminals ALONG with the stock wiring hookup. So the current splits and goes thru BOTH the meter and around it. This reduces the needle waving but degrades the accuracy. In the case of the Pantera, stock accuracy is not great anyway. The gauge basically tells you the alt is putting out current; how much is another issue.

My shunt is a simple piece of 0.060" brass shim about 1/4" wide x as long as is needed to stretch from gauge post to gauge post. The larger the shunt's surface area, the less current goes thru the meter. Its a good idea to use shrink wrap or other insulation on your shunt since its carrying a LOT or current!

I have already installed a shunt as specified by bosswrench but unfortunately this does not prevent my ammeter needle from bouncing around.
