| 1. | Be sure there is no play in the fuse holders, and that the fuses are held securely. |
| 2. | Are the fuse capacities for each circuit correct? |
| 3. | Are there any blown fuses? If a fuse is to be replaced, be sure to use a new fuse of the same capacity. Always determine why the fuse blew first and completely eliminate the problem before installing a new fuse. |
