All true, Ken, which is why I worded the comment as I did. However, he's
indicated that he intends to replace the existing wiring with new, larger,
conductors. He seems knowledgeable enough to correct those other voltage
issues too. They're really not all that troublesome in a well maintained
system -- witness the many millions of one-wire alternators running today.
