This can be done with a test light to see if current is passing through the fuse in the fuse block, or by using an multimeter (VOM) set to 20 VDC to check to see that there is voltage into and out of the fuse or cb. If the fuse/cb is removed from the fuse box it can be tested for continuity using the ohm setting of the VOM. |
Newer vehicles often have the relay located under the dash adjacent to the fuse box or in that general area. These relays will click loud enough when the horn is pressed that they can be heard. This will help to locate it as well as give an indication that current is at least reaching the relay- although the current may not be passing through it. | Newer vehicles often have the relay located under the dash adjacent to the fuse box or in that general area.
