Road Test And Performance Adjustments; Delayed Or No Trailer Brakes; Aggressive Or Grabby Brakes - Hayes ENERGIZE III Installation Manual

Road Test and Performance Adjustments

To adjust the gain wheel (Figure 1) with the trailer connected.
A. Locate the tow vehicle and trailer on a flat, hard, dry surface.
B. Adjust the gain wheel to the midrange setting.
C. At a moderate speed (25 mph or less) push on the tow vehicle brake pedal in a normal manner. A
firm braking action should occur.
D. The red indicator light should illuminate from dim to bright during the stop and back to dim after the
stop is completed.
E. If more trailer braking is required, increase the gain wheel. If less trailer braking is required,
decrease the gain wheel.
F. At a moderate speed (25 mph or less) move the manual lever slowly to the left. A much harder
stop can always be obtained, as the gain wheel setting does not affect the manual lever. The red
indicator light should illuminate from dim to bright during the stop.
G. At a moderate speed (25 mph or less) press the manual remote button slowly (only for ENERGIZE
XPC with remote option). A much harder stop can always be obtained, as the gain wheel setting
does not affect the manual remote. The red indicator light should illuminate from dim to bright
during the stop.
H. Readjustment of the pendulum-leveling arm: If the conditions described in items 1 and 2 below
occur, refer to Figures 2, 5, and 6 for the affects of pendulum leveling arm adjustment
1. Pendulum leveling arm adjusted too far to the rear of the controller (Figure 5):
• No indicator light
• Delayed braking
• No braking
2. Pendulum leveling arm adjusted too far toward the front of the controller (Figure 6):
• Steady illuminated indicator light
• Grabbing trailer brakes
• Trailer brakes will pulse with 4-way flasher light
3. Pendulum leveling arm adjusted correctly (Figure 2):
• Dim indicator light when vehicle is stopped on level surface
• Increasing indicator light as pedal effort is increased while stopping
• Smooth braking
