Armageddon Relay Notes
You may receive a version of the Armageddon Headlight Relay with differently coloured wires. However it will hook up in the same way. The colour key is:
|Old Version||New Version|
|Black Wire With Orange end||Black Wire|
|Red Wire with Purple end||Red Wire|
|Red Wire with Yellow end||Purple Wire|
|Red Wire With Green end||Orange Wire|
This guide will refer to the colours of the NEW VERSION - consult this table when connecting the relay if you received the OLD VERSION.
Step 1: Battery Lock Removal
Remove your bike battery and discharge any excess electricity by holding the POWER button.
Use a phillips screwdriver to remove the screw holding on the battery removal toggle switch.
Use the 3mm Allen Key to remove these three screws holding in the battery lock
The battery lock can then be easily slid out
Step 2: Vampire Tap Installation and Power Wire Installation (Classic DUO)
Take the "Headlight Power Wire" and prepare it for installation. Take this and the Female Spade Connectors. Crimp the Female Spade Connectors onto the end of the "Headlight Power Wire" closest to the inline fuse - circled in blue below. Note you may need to strip off a bit of the covering on the wire before crimping on the connectors.
Open up the motor cover by removing these three screws with a 2.5mm Allen Key
Pull out the dualizer to get access to the power wires
You will use the two circled wires on the dualizer for the installation of the vampire taps. The BLUE wire is POSITIVE and the BLACK wire is NEGATIVE.
Place the vampire taps around each power wire and clamp them with a pair of needle-nose pliers until you hear them click closed. Ensure that the taps are slightly offset so they lie flat beside each other.
Note while the wire colour in the above images is different the process will be the same
You should now have the vampire clips connected to the dualizer looking like this:
Now take the "Headlight Power Wire" and thread the end without any connectors through this hole connecting the motor cavity to the downtube.
Plug the "Female Spade Connectors" at the end of the headlight power wire into the vampire connectors you installed. The red wire will plug into the vampire connector attached to the blue wire. The black/red wire will plug into the vampire connector attached to the black wire.
Now fish this "headlight power wire" through the inner tube in the downtube like in the image below
Step 2: Vampire Tap Installation and Power Wire Installation (Ultra DUO with TYPE 1 Range Extender Connector)
Step 2: Power Wire Tapping, Installation and Headlight Wire Preparation (Ultra DUO with TYPE 2 Range Extender Connector)
Remove the three circled screws with a Phillips Screwdriver to take off the motor cover.
Locate the wire that connects to the stock headlight. Pull that wire into the downtube through the hole on the side.
Snip the stock connector off of the wire like below.
Strip the large, outer layer of insulation from the wire.
Strip the ends of each individual wire.
Attach the female spade connectors to the wire and crimp the connectors down so they are secure and connected.
Plug the black wire with the white stripe on it into the red wire on the relay
Plug the black wire into the black wire on the relay
Now get the "Headlight Power Wire" ready. When installing the "Headlight Power Wire" you need to have the end of this with the fuse closest to it (fuse is circled below) closest to the motor.
You will want to attach some cord/wire/string to this to help with fishing the "Headlight Power Wire" through the frame - see image below for an example of this. Also put some electrical tape on the leading end of the wire.
Thread this wire through the internal circled below in the downtube of the bike starting from the top going towards the motor cavity.
The headlight wire needs to get into this hole between the downtube and motor cavity below
Once you have the "Headlight Power Wire" into the motor cavity pull it further so it exits past the cutout/hole circled in red below. If you do not thread it out through this area you will be unable to put the motor cover back on. You can now remove the threading line and electrical tape from the "Headlight Power Wire".
Next unplug the Anderson Connectors (The black and red square connectors - see below image). When unplugged you need to determine which wires are coming from the motor and which are coming from the dualizer.
THIS PART IS VERY IMPORTANT - IF YOU USE THE INCORRECT WIRES FOR THIS PART YOU WILL NEED TO DO REPAIRS ON YOUR MOTOR
You will need to pull each of the ends and see which has slack and extra length. In the example image below the pair of wires circled in red is coming from the motor and are NOT the wires you do not want to use for the next steps. The wires in green are coming from the dualizer, and are the ones you DO want to use.
Snip the red power wire a few inches back from the connector
Strip back about 10mm of insulation from each end of the wire. Line up the silver butt connector with the cut section of wire with the Anderson connector attached to it. Then crimp on the end of the butt connector to the wire - see the images below. Slide a length of heatshrink over thiswire beforeproceeding
Slide heatshrink over this wire end
Strip back both of the ends of the "Headlight Power Wire" that were brought down into the motor cavity
Next take the end of the red power wire you snipped coming from the dualizer and hold it by the red, now stripped end of the "Armageddon Headlight Wire". Put both ends into the butt connector so they are contacting and crimp the connector down
Now repeat this process with the Black Power Wire coming from the dualizer and the black wire on the "Headlight Power Wire". When both have been connected use a heat source to shrink down the heatshrink and you should have two wires looking like this with the "Headlight Power Wire" butt connected into the Dualizer Power Wires like below.
Plug these connectors back together matching black to black and red to red. When plugged in they can be connected with the sliding notches together. When connected cover the connectors with electrical tape to ensure they remain secure like in the image below.
Push the wiring into the space within the motor cavity area. Last reinstall the motor cover and advance to the next section.
Step 3: Headlight Mounting
If you still have the Stock Bike Headlight installed at this point please unplug and remove it now!
Head Tube Mounting Steps
The headlight assembly mounts on the steer tube – so the stem needs to be removed to install it. Loosen the two bolts on the side of the stem then remove the top cap bolt with the 5mm hex key. If the bike is in a stand, support the front wheel as the fork will drop through the head tube once the stem is removed.
Remove the stem and handlebars then slide the headlight mount over the steer tube on top of one headset spacer. Reinstall the remaining headset spacers along with the stem and handlebars.
Tighten the top cap bolt first, followed by the bolts on the side of the stem. The top cap bolt adjusts the preload on the headset bearings so be sure not to over tighten it. Refer to your bike model’s assembly guide for steps on properly adjusting your headset: https://biktrixhelp.zendesk.com/hc/en-us/categories/360001643632-New-Rider-Resources.
Fork Mount Steps
If you have an RST fork and a light with a specific mounting bracket you can mount it to the fork following these instructions:
Step 4: Connecting the wires
Note: For the Ultra DUO with TYPE 2 Range Extender Connector you may have already done some of these steps - if so just ignore them below
Pull the wires coming off from the Armageddon light into the downtube - you will need to remove the plastic grommet to insert them. They will be around the same part of the bike downtube where you pulled the "Headlight Power Wire" into in Step 1.
Pull the stock headlight wires (2 small black wires with small metal connectors) into the downtube so they are in the same cavity as the Armageddon Headlight Wires.
Note: The wire with black dashes will be positive 95% of the time - occasionally it may not so keep this in mind later in the installation process.
Install the provided "Female Pico Connectors" onto the "Headlight Power Wire". These will need to be crimped on with a pair of needle-nose pliers. The wire may need to be folded over so the "Female Pico Connector" has a big enough surface to clamp on. When these connectors are attached cover the end touching the bare wire with either electrical tape or heatshrink.
Now take your "Armageddon Headlight Relay" and start hooking up the wires as follows:
Relay Red wire → Stock Positive Headlight Wire (Black with white Stripe)
Relay Black Wire → Stock Headlight Negative Wire (Black with no stripe)
Relay Orange Wire → Armageddon Light Orange Wire (Colouring may also be like image below)
Relay Purple Wire → "Headlight Power Wire" Positive Wire (the RED wire)
Armageddon Light Black Wire With Blue → "Headlight Power Wire" Negative Wire (the BLACK wire)
With all of these wires installed this is a good time to check if the light is working and if you have hooked everything up properly.
Put on your range extender battery if you have one, turn on your display and power on the light. You can do this the same way that you turn on the stock light for the bike.
If the Light does not turn on try and swap the stock headlight wires connections to the relay as so:
Relay Red wire → Stock Headlight Wire --- Black
Relay Black Wire → Stock Headlight Wire --- Black with white Stripe
When the light is turning on use some electrical tape or included heat shrink to cover all of the connections except the ones with covered space connectors to ensure they stay securely hooked up.
Step 5: Final Assembly
Now, you can carefully tuck the relay and connections behind the upper battery lock. Lastly screw the battery lock back in place.
