Mallory Ignition ACCEL 500+ ELECTRONIC IGNITION CONTROL 49500 - Manual (Page 11)

RING TERMINAL CONNECTORS:
Furnished with the ACCEL 500+ Electronic Ignition Controls
are two Ring Terminal Connectors for the
convenience of getting a neat installation when the
ACCEL 500+ Electronic Ignition Control is added to an
existing ignition system. These Ring Terminal Connectors
allow the existing ignition system wiring to remain in the
area of the ignition coil.
• Move wires onto the stud that is inside the Ring Terminal
Connector body.
• Secure these wires to the stud with the nut and washer.
• Install the Ring Terminal Connector cap.
(2c) Wiring Method without adapters for Magnetic
Pickup Trigger Pulses (Non-Computer Type); Magnetic
Pickup Distributors or Crank Trigger Ignition
Connecting to Magnetic Pickup Distributors and Crank Trigger
Ignition – Refer to Figure 14.
• Connect the magnetic pickup (+) wire to the SMALL
GREEN WIRE from the ACCEL 500+ Electronic Ignition
Control.
• Connect the magnetic pickup (–) wire to the SMALL
BLACK WIRE from the ACCEL 500+ Electronic Ignition
Control.
Connecting the Ignition Control Harness:
• Route the Ignition Control Harness to the ignition coil so
that its wires do not make contact with extreme heat,
sharp objects or moving devises such as fans, belts and
linkages.
• Connect the RED WIRE to the 12-volt wire from the
ignition switch. NOTE: The RED WIRE must get voltage
when the ignition switch is in the START and RUN
positions. Use a Ring Terminal Connector to join wires
together.
• Connect the YELLOW WIRE to the ignition coil (+)
terminal. DO NOT allow any wire except the YELLOW
WIRE to make contact with the ignition coil (+) terminal.
• Connect the BLACK WIRE to the ignition coil (–) terminal.
• DO NOT connect the GREEN WIRE of the Ignition Control
Harness to anything. Tape the end of it to
insulate it.
• Go to Step 3, Page 11.

Step 3
Tachometer Operation:
If a tachometer is used, connect tachometer ignition
sensing lead to the TACH terminal on the ACCEL 500+
Electronic Ignition Control.
If the tachometer does not work after being connected to
the TACH terminal, connect the tachometer ignition sensing
lead to the GREEN WIRE from the Ignition Control Harness.
If this does not work, your tach is a high voltage trigger
tach and will require the Mallory Fuel Injection and
Tachometer Adapter Part No. 29074 or 29078 to supply the
proper signal for the tachometer to operate.
BYPASS CONNECTOR
The Bypass Connector (standard ignition bypass) fits into
the mating plug of the Ignition Control Harness to convert
back to standard ignition. If you use the Bypass Connector,
use ignition ballast resistors designed for the particular
distributor and coil in the wire from the ignition switch. Use
the Power Plug to convert back to standard ignition. Also, if
you are using a Mallory Fuel Injection/Tachometer Adapter
(Part No. 29074), disconnect it (and its diode if used) as
part of converting back to standard ignition. The Bypass
Connector (standard ignition bypass method to convert
back to standard ignition) does not work with magnetic
pickup distributors or crank trigger ignition.
Step 4
Secure all wires with cable ties to prevent contact extreme
heat, sharp objects or moving devices such as fans, belts
and linkages.
Step 5
Recheck all wire and connections to ensure they are
correct before applying power.
Step 6
Connect the battery (–) terminal cable. Start engine and
check operation of the ignition system.
Ignition Control Operation and Features
ACCEL 500+ 49500 CD Ignition System
The features of the ACCEL 500+ Ignition System are
controlled by using the hand held controller. The “Mode”
key controls which feature is being adjusted and the value
is changed by using the up and down arrow keys. To use,
simply connect the cable provided between the controller
and the main unit. When finished, you can either remove
the cable and controller for safe storage or leave it
connected. The features and their mode numbers are
listed below along with appearing on both the controller
and the main unit.:
RPM Limiting Modes 1, 2, and 3- Utilize in sequence.
Mode 1 – This is the normal engine protection RPM limit. It
is active if no other RPM limit is selected. The range of this
limiter is 1000 to 12800 in steps of 100 RPM.
