I was on a conference call with a few electrical engineers in California about this the other day. I know it is a real concern beyond a shadow of a doubt. The problem exists if you go higher in amps than the ammeters internal protection which is 50 amps.
When I told them the idea of using a radiator clamp in a horseshoe configuration, one of them laughed and said its something he would have done when he was 14, but now that he understands the need for a balanced system, no way.
Mr Herbison, if you choose to tell people not to worry about it, and they take your advice and go about their lives and their house burns down, that's on you. I do not want that on my conscience.
The problem with just stuffing any old piece of metal back there is it changes the accuracy of the meter. You want full deflection of the meter. Since these trucks didn't come with a shunt, and the late 60's Impala was set up with a fuse to fix that problem then I feel the next best thing is to fuse the circuit. But I do not know if these higher amp alternators would go to their max output under any conditions we might run across.
I know its easier to just move on, but its not serving anyone. Lets try and get to the bottom of this. This right here is why I do not EVER take one persons word for anything. Jerry in this case you are just dead wrong and dangerous at the same time. Today's crop of new admirers/owners of these trucks will just blow it off and then cry when their entire family is wiped out in a fire. I couldn't sleep at night and probably won't until I figure this out.
