IX. 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 on
during power up, the button will be disabled and the following message will be displayed until a button is pressed:
Button is Stuck!
If this condition occurs, the Control Box will still function and adjust fuel properly. The Control Box can be sent back to
Boondocker to be serviced. Contact Boondocker to get an RMA number (Return Merchandise Authorization) before
sending your unit.
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 following error messages.
Injector 1 Fault No signal detected on the MAG side (yellow wire).
Injector 2 Fault No signal detected on the PTO side (green wire).
Injector x Fault An error occurred that did not get cleared (by pressing any button) before the
engine was started again.
If any of these conditions occur, the Control Box will still try to function and adjust fuel properly. Contact Boondocker
to determine if the Control Box and harness need to be sent back to be serviced.
Other Issues
Engine runs erratically:
1. Verify that the EFI Harness Ground Wire has a good connection.
2. Verify that all wiring is in good condition (not cut or melted) 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.
3. Unplug the EFI harness and plug the stock connectors onto the injectors and verify that the sled runs OK. For this
test, do not run engine under any conditions where it will not get enough fuel.
4. If problem only occurs with Control Box plugged in, change all fuel adjustment settings to 0 and see if the problem
persists. This will isolate the problem to either the Control Box or to the fuel settings used.
5. 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.
Rough Idle: Idle adjustments are much more sensitive than other adjustments since the injectors are on for a very
short duration. You may not be able to adjust your 3000 LO settings by very much.
LCD characters are dim: If you are using a 9 volt battery to power the box when the sled is not running, your battery
voltage is getting low – replace your battery, even if the back light is on. Extreme hot or cold
temperatures may cause the LCD to not display properly.
