I hate to bust ur bubble , but mine has been running that way for about 10 yrs. now , but the car has been rewired , msd/fast 2.0 fuel inj. , no ballast resister ,
battery in trunk i
Battery cable from the rear runs up the pass. side to inside at at front pass. side firewall , relay is close to where the heater motor used to be , heater is under the dash now .
Length of welding cable that was given to me dictated where the relay would be located , didnt have room for any heater motor there anyway = raised port heads are big.

You haven't busted any bubble and neither your nor my answer is the "doomsday" either direction. But it is poor practice, and as loads get bigger and alternators get bigger, the drop involved gets worse. As I attempted to explain, it also depends--on whether it's externally regulated and whether the loads come off the main cable. It STILL is poor practice, And I'm not an advocate of no 00000000 cable for the charging line, either LOLOL

Tell you what you do..........some day when you ain't busy create a "worst case" situation. You start your car when the battery has been sitting. The fans pumps whatever are running and the battery is low from sitting. The alternator is really charging. Now put a meter between the output stud on the alternator and the battery positive post---or the main power junction up front---and see just what the drop is. If it's less than 1 1/2-- 2V I'll lbe surprised
