It's not a bad idea Fred. Still looking for that perfect solution that doesn't halve the deflection. Maybe try and find a 100 amp gauge and transfer the guts into ours? That's what it's all about, bantering ideas back and forth until a solution presents itself.
If I knew these high output alternators would never reach more than 50 amps fusing it would work too. Or a way to limit the output of the alternator? Congrats on getting your GMC finished.
