Headlight warning light:
Each headlight motor has a microswitch on it that's "normally
closed" unless the headlight bucket is fully open, and the
switches are powered from the headlight switch. If you turn the
lights on and the buckets aren't fully open, the micro switch
circuit is grounded, illuminating the flashing light in the
cluster; when the buckets are fully open (both of them - there's
a switch on each bucket, and they're in series), the circuit
opens, and the indicator light gets no power.
Radio Speaker:
This is important - If you replace the speaker with a typical
current 4-ohm speaker, you'll fry the output transistors in the
radio; the replacement must be 10 ohms Most current replacement
speakers are 4 ohms and if you use one of those without a
matching transformer, it'll eventually blow the DS-501 output
transistors in the radio.
Green and black are the speaker wires, and the other plug is
radio power (yellow), radio dial light (gray) and ground
(black). NOTE: There is a second black pigtail wire from the
radio connector ground wire cavity with a ring terminal that
screws to the instrument panel brace - make sure that's in
place, as it's the ground for the whole rear end of the car (all lights, fuel tank
sending unit, coupe rear blower, etc.).
Coil/Resistor/Ballast:
The stock setup has two pink wires connected to the coil (+)
terminal, and the black wire from the distributor is connected
to the coil (-) terminal.
A 12-ga. pink wire comes through the grommet in the firewall
from the ignition switch and connects to the bottom terminal on
the ballast
resistor, and another 12-ga. pink wire from the
engine harness connects to the top terminal on the
resistor
(the other end of that wire is at the + coil terminal).
The other pink wire (18 ga.) at the coil (+) terminal is also in
the engine harness, and comes from the small "R" terminal on the
starter solenoid; it feeds a full 12 volts to the coil when
cranking. If the harness is
original, both pink
wires are crimped to one spade connector at the coil connection.
If the car has a radio, there's also a capacitor attached to the
coil bracket - its black lead also connects to the coil (+)
terminal.
The only two external ballast resistors ever used on Corvette
were 1931385 (0.3 ohm Black Dot) and
1957154
(1.8 ohm Blue Stripe). All 1965 used
1957154
Mini Starter wiring:
In early original wiring harnesses, the ‘R’ circuit was a
ballast resistor bypass. This terminal is ‘no connection’ when
the starter is at rest, and is +12VDC while cranking.This
circuit provided +12VDC to the ignition coil during cranking for
easier engine starting. Cars that do not have a ballast resistor
(i.e. HEI, MSD, or other aftermarket ignition systems) should
not need this connection. In most cases, this wire can be
eliminated. If the engine has no ignition during cranking, then
the wiring of the coil is going to require an ‘R’ terminal
signal. To accomplish this, connect a 3A/400PIV diode (or
Powermaster part # 600 or Jegs #555-10038) in line with the
MOTOR SIDE of the solenoid. (Note: This is the terminal on the
solenoid which has the cable from inside the starter motor
connected to it. It is opposite the BATTERY terminal on the
solenoid. The cathode or banded end of the diode goes away from
the starter. This allows current to go from the starter to the
coil and yet not from the coil to the starter.)

Parking Brake adj:
1. Loosen parking brake cables at equalizer until brake levers
move freely to the "off" position.
2. Tighten adjusters until discs will not move.
3. Back each adjuster off 10 notches.
4. Apply parking brake from inside of car 4 notches.
5. Tighten brake cables at equalizer to produce a light drag
with the wheels mounted.
6. Fully release parking brake handle and rotate the back
wheels. No drag should be evident with the handle released.
7. Try burnishing the shoes. |
