Nothing wrong with the holder. It just answers what type of alternator that is. By design it should have a field current of what? 6-7 amps mimimum. That going through 18 gage wires that have been spliced onto 16 ga wires. That's not even including the electric choke assist. The main 16 ga wire has to carry those 7 amps for the field, plus the 3 or 4 amps for elctronic ignition plus whatever else was added to the run circuit that year. No thanks!
