FUSE
Electric starter model
- Remove the motor cover.
- Remove the fuse case cover and pull off fuse.
(1) Main fuse: 30A (white fuse case): All electric starter model
(2) ECM fuse: 10A (yellow fuse case): DF25AT/25AR/ 30AT
- Inspect the fuse and replace with new fuse if needed.
If a fuse is blown, try to determine the root cause and correct it.
If the cause is not corrected, the fuse may be blown again.
If you replace a blown fuse with a fuse having a different amperage rating or with a substitute such as aluminum foil or a wire, extensive electrical system damage and a fire may result.
Always replace a blown fuse with a fuse of the same type and rating.
If a new fuse blows in a short time after installation, you may have a major electrical system problem.
Consult your SUZUKI marine dealer.
