IX. Control Box Troubleshooting
Stuck Button
When the Control Box is first turned on, all buttons are checked to verify that a button is not stuck on. If a button is
detected to be on during power up, the button will be disabled and the following message will be displayed until
another button is pressed. To verify if a button really is stuck on, re-power the box without pressing any buttons.
Button is stuck!
Note: A common problem is a bad ground connection on the sled causing the box to keep resetting itself. If a button
is being pressed when this occurs, the “button stuck” message will be displayed. Start the sled without pressing a
button and see if the message goes away. If it is not present, start looking for a disconnected ground on the sled (see
Other Issues below).
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 erratically:
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.
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, or the seal on the back-side will be protruding out farther
than the rest.
4. Unplug the EFI harness and plug original harness back into the injectors and verify that the sled runs OK.
5. If problem only occurs with Control Box plugged in, change all fuel adjustment settings to 0 and see if problem
persists.
