Anyone out there know the basic wiring for a 57 283 upgraded to a HEI
ignition and an alternator with an internal voltage regulator? I'm trying
to straighten out the wiring from someone else's unsuccessful attempts. The
truck would run, but no charging system and a lot of non-functional
electrical. The shop manual I have is little help, since not much is
original.
I want to use the original volt meter if possible. I know the positive
wire from the alternator goes to the horn relay and the ground goes to a
ground on the firewall. Here's where I start to get confused. The
alternator wire from the "1" connector (wht) goes to the voltmeter (which
side), right? The number "2" wire (blu) goes to the horn relay also, right?
If so, can the positive wire from the alternator and the number "2" wire be
spliced together at the alternator since they both go to the same terminal
on the horn relay? And last but not least, if the "1" wire goes to the
voltmeter, where does the wire from the other voltmeter terminal go? It
looks like it goes to one of the terminals on the ignition switch, but the
diagram isn't too clear.
I know this shouldn't be too complicated, but I'm losing this battle. Any
help would be greatly appreciated, as I don't want to fry whatever the
previous owner hasn't already. Jon Elerath was kind enough to send me his
diagrams, but mine's too different from his for me to figure it out. I've
replaced the alternator, removed the old voltage regulator (which was still
wired being used as terminal block from what I could tell), and removed the
resistor block that was still wired between the distributor and ignition
switch (although it was fried too). Thanks, guys.
