Bandolero Kill switch installation procedure.
Written by Greg MacLean, March 30, 2014
AME Enterprises’ Kill switch rule states that a kill switch is to be mounted on the left side rear deck of
the interior tin (see pic #1), and it must shut off the engine and fuel pump.
Pic #1 - Location where Kill Switch is to be mounted.
The ignition system on a Bandolero car is similar to the ignition system on your hand push lawnmower.
It doesn't require battery voltage to generate spark. Instead, it generates its own spark via a flywheel
magnet and a set of magnetos/coils. What this means is your engine will continue to run even if you
pull the cables off of the battery. To get the engine to stop running the small black diode wire from the
coils must be grounded out, the same as your lawnmower. As soon as the ignition is grounded out and
the engine quits, the crankcase pulse operated fuel pump will stop pumping fuel. To meet the kill switch
rule you simply have to run a wire (14-16 gauge will suffice) from the ground terminal on the engine to
one of the kill switch's small terminals, then from the other small terminal on the kill switch to a good
chassis ground. The engine ground terminal is located on the front right side of the motor as it sits in
2|Page
the car (see pic #2). The threaded stud has a #8-32 thread. An easy way to make the connection here is
to put a small wire eyelet over the stud and secure it with a second nut, preferably a nylock nut.
Pic. #2 - Ignition ground terminal location. Nut size is #8-32.
The kill switch to be used should be robust enough to withstand the severe vibration present in a
bandolero car (See pic # 3 of a commonly used kill switch). If you have a kill switch with two large
terminals you can use those terminals to wire up your ground circuit. If you have a kill switch with two
large terminals and two smaller terminals, you can use the two smaller terminals to make your
connections.
It's important to understand that the kill switch's "On /Off" locations will have to have the labels
reversed for a Bandolero car. The switch's normal "ON" position will actually be making a connection
inside the switch to ground the ignition out, shutting the engine OFF. To get your engine to start, the
kill switch will have to be switched to the normal "OFF" position. Clearly mark your switch so that "OFF"
shows that the engine will shut OFF with the switch on that position.

Pic #3 - Typical Kill switch. This one has two large terminals and two smaller terminals. Because the
wire size is small you can use the two small terminals with this type of switch.
There have been occasions when the magneto/coil wires have become unplugged underneath the red
cooling shroud on the bandolero engines. If this happens, even the kill switch will not shut off the
engine. To address this, AME is asking all racers to install a simple spark plug wire "pull off loop" for the
front cylinder and the rear cylinder (See pic #4). All this requires is two plastic ties per ignition wire.
These loops will permit pulling the spark plug wires off of the sparkplug while lessening the chance of a
shock to the person pulling the wires off.
Pic #4 - Spark plug wire pull off loops. Install one on each of the two spark plug wires.

Legends Car Kill switch installation procedure.
Written by Greg MacLean, March 27, 2014
AME Enterprises’ kill switch rule states that a kill switch "must shut off the engine and fuel pump".
Normally the ignition and fuel pump power are shut off via the ignition "On/OFF" switch located on the
interior dash. However, in case of an emergency situation, "the track" wants to be able to shut all
power down with a kill switch which "is to be mounted high on the left side rear deck of the interior tin"
(See pic 1 indicating location). The roll cage beneath the sheet metal makes this a tight fit for the switch
on some models of Legends cars (i.e. '37 Coupes). The Longacre kill switch shown is pic 2 measures just
over 2 5/8" at its widest point. But remember that the hole size for the threaded retaining portion of
the switch only has to be approximately 3/4" in size. If your kill switch will not fit on the tin horizontal
surface AME will permit owners of the smaller style coupes to mount them on the vertical surface of the
tin, just behind your left shoulder. Ensure the ON/OFF positions are clearly indicated.
Master disconnect switches come in 2 main types. One type simply interrupts one of the battery's main
heavy cables. I recommend installing it on the ground cable side to prevent running heavy current to
and from the kill switch. Interrupting the ground cable does the same job without the chance of a short
circuit. The second type has the same battery heavy cable connection terminals as the first type, but in
addition it has two smaller terminals to disconnect power to the alternator field. The second type is the
type required for Legends cars (See pic 2). The reason the second type is required is as follows. If you
disconnect either the positive or negative battery cables from the battery while the engine is running, it
will continue to run. This is actually a tech inspection procedure to ensure your alternator is
operational. We need to stop the alternator from charging to shut the engine down. To do this, the kill
switch's small connections are used to interrupt the alternator field wire. Note: An ohmmeter was used
on the Longacre switch pictured to confirm that the small terminals and the large terminals were
separate (non-connected) circuits inside of the switch. If you use a different switch confirm this.
To start your kill switch installation, disconnect both battery cables at the battery. Next, locate the
alternator field wire on the front side of the firewall area (see pic 3). The wire is tagged "ALT Brown"
from the factory (although the actual wire from the alternator on 1250 sealed motors is blue, and turns
to brown on the firewall side of the connector). I recommend that you leave the factory connector in
place. Follow the wire back towards the alternator and when you are approx. half way between the
alternator and the factory connection cut the field wire (blue wire on 1250s, brown wire on 1200s).
Now connect a new wire (of the same size) to the end of the cut wire that comes out of the firewall
connection. Carefully run this wire back through the firewall, along the square bar found inside the
passenger side door, across the area behind the seat (outside of the sheet metal) to one of the kill
switch small terminals. Connect another new wire to the other small terminal on the kill switch and run
it ahead (beside the first wire) to the alternator wire that you previously cut. Make a connection there.
Tie the two wires up carefully so they don't rub or chafe through resulting in a short. Use a grommet
where you go through the firewall. Basically what you did was cut the alternator field wire and installed
the kill switch small terminals "in the cut". It just took two long wires to get you back to the kill switch
location.
To connect the battery ground cable to the kill switch heavy connection terminals first insure the Kill
switch is in the "off" position. Next run one heavy cable from the battery negative terminal up to the
5|Page
switch and bring another heavy cable back down to the ground connection on the right hand battery
hold down stud. Now connect the positive cable to the battery. That should be it. To check that for
proper operation, turn the kill switch to the "On" position, make sure your transmission is in neutral,
and start your engine in the usual manner. Test the kill switch by turning it to the "Off" position with the
engine at idle to ensure the engine and the fuel pump stop running. Before you pat yourself on the
back for a job well done, ensure you turn the dash ignition switch off. It's a good habit to shut your kill
switch off when you're not racing to prevent battery drain (i.e. from the transponder).

Note wire is brown on the upper side of the connector, and blue on the lower side of the connector. On
older motors (i.e.1200s) the blue wire will be a brownish red color. It will be smaller than the larger red
charging wire from the alternator. DO NOT CUT THE LARGER RED WIRE FROM THE ALTERNATOR!
The black cable on the right hand side is the ground cable. Install your kill switch heavy
terminals in the ground cable circuit (i.e. from the negative battery post to the kill switch, back to the
ground stud
