IPA Tools 9005A Super MUTT Head - Manual (Page 13)

13
Your MUTT ® comes supplied with a 10 ft. ground cable accessory. Plug in
the 10 ft. ground cable to the MUTT ® Chassis Ground outlet (Fig. 1-N, Pg.
10). Then using the alligator clip, attach the other end of the ground cable to
the chassis of the trailer. This effectively grounds your trailer and allows
testing to continue.
10. After the Ground Integrity test, the control knob (Fig. 1-L, Pg. 10) may be rotated
in either direction to select a circuit to diagnose. The corresponding Circuit Indica-
tor (Fig. 1-M, Pg. 10) illuminates indicating the selected circuit.
AUTO CYCLE MODE
NOTE: Cannot be accessed when auxiliary or brake circuit is selected.
1. After Ground Integrity has been established, momentarily push and release
the Control Knob (Fig. 1-L, Pg. 10). The Auto Cycle Indicator (Fig. 1-I, Pg. 10)
illuminates.
2. Power is applied by the MUTT
® to one circuit at a time for five seconds in a
clockwise direction starting from the Ground Integrity Indicator (Fig. 1-K, Pg. 10).
3. A five second delay commences before power is applied to the first circuit
automatically.
4. To pause or stop the auto cycle mode, momentarily press and release the control
knob, turning off the Auto Cycle Indicator.
MUTING WARNING SOUND
How to override warning sound:
• Flip the Mute switch up to disable audible alerts, or press the control knob
(Fig. 1-L, Pg. 10) for five seconds. Mute can not be accessed when AUX or Brake
Circuits are selected.
• To restore sound, return the switch to down position and/or cycle power using the
Power Source switch.
ALL CIRCUITS ON (OVERRIDE)
Turns All Circuits On (maximum load amount 20 amps total).
All Circuits On mode can be accessed by the control knob or remote control:
• Hold down the control knob for ten seconds. Listen for the second beep and
release control knob.
• Hold down the large button on remote for five seconds. On trailers using
incandescent bulbs, All Circuits On will typically result in an overload because the
amperage draw will exceed the allowed 20 amp maximum.
NOTE: Short Circuit sensing is operational in this mode. If a short circuit is found
in this mode, the MUTT
® will not be able to identify which circuit is the cause of the
short. Open Circuit sensing is not operational.
• To cancel All Circuits On mode, turn the selector knob or press and release the
large remote button.
