Symptom Possible Cause and Solution
All problems. Many system problems are caused by issues with the power supplied to the DVR.
Check the following:
• The voltage to the system may be too low. Check the
LOW VOLTAGE indicator
on the back of the DVR. See “Back panel” on page 1–6 for location of the
LOW VOLTAGE indicator.
• The power harness from the DVR must be connected as close to the battery as
possible. Check the wiring to the battery. See “2.6. Step 5: Connecting the
Power and Ignition Harness, Fuses, and Fuse Holders” on page 2–10.
• Check the in-line fuses and fuse holders. If a fuse is blown, determine the
cause before replacing it.
