If a button really is stuck on, the Control Box can still function and adjust fuel properly. The Control Box can be sent
back to Boondocker to be serviced.
Injector Fault
The Control Box monitors the signals from the sled’s ECU. If it detects signals on one set of wires but not the other, it
will detect a fault on that injector and display one of the two error messages.
MAG Inj. Fault!
Missing or bad signal detected on the MAG side injector (yellow or tan wire).
PTO Inj. Fault!
Missing or bad signal detected on the PTO side injector (green or brown wire).
xxx Inj. Fault!
This means a previous injector fault has occurred which has not yet been
cleared.
If any of these conditions occur, the Control Box will still function and it will still try to make fuel adjustments, but
the intermittent injector connection will need to be fixed. Contact Boondocker to determine if the Control Box and
harness need to be sent back to be inspected or serviced.
Note 1: Injector errors that occur infrequently can be ignored since they are likely caused by sporadic electrical noise.
Note 2: It is possible for the sled to run but the wiring harness to be wrong – the box cannot make proper fuel
adjustments. If you see an injector error, first recheck the wire positions in the black connectors according to
the tables in these instructions.
Other Issues
Engine runs erratic:
1. Verify that the ground on the sled’s harness (heavy brown wire) has a good connection to the chassis. On the M7
model, this ground is connected by an eyelet attached to the bolt at the base of the steering support hoop on the
Mag side of the sled (close to the gas tank)
Note: The nut that holds the ECU ground wire on M7 sleds is known to come loose!
2. Verify that the EFI Harness Ground Wire has a good connection.
Note1: Arctic Cats require that this ground wire on the Control Box must be connected to CHASSIS
GROUND (not Engine ground!).
Note2: If the headlights have been removed (hood is removed or aftermarket hood is used), the electrical
system can cause interference with the Control Box. We recommend using a 100W power resistor to place a
sufficient replacement load on the electrical system.
3. Verify that all wiring is in good condition and that the wires have not pulled out of the terminals. To verify this,
look inside each connector and verify that the terminal pins are all at the same height. If a terminal is starting to
back out, it will appear to be lower in the connector.
4. Unplug the EFI harness and plug original harness back into the injectors and verify that the sled runs OK (test can
only be done at low rpms before boost comes on).
5. If problem only occurs with Control Box plugged in, change all fuel adjustment settings to 0 and see if problem
persists.
6. Verify that the Control Box does not reset itself when the sled is running by doing the following:
a. When the sled is first powered up, change the menu screen on the Control Box to one of the fuel adjust
screens.
b. Run the sled.
c. Before shutting off the sled, verify that the screen is still on the same menu selection.
d. If the startup screen is displayed (showing version number etc.), the box has reset itself. This is likely
caused by bad voltage to the box due to an intermittent connection.
