Need to locate the location of the circuit breaker on a 1992 Electra Glide


The main circuit breaker is under the right side cover. The rest are under the fairing.

When checking outside light the timer is going to, the multimeter reads 120v but the lights will not turn on. There are also outside outlets on the same circuit and they are reading 105v but cannot run...


Turn off power between each action listed below.

Is dial rotating and keeping time on timer?
This will tell you if 120V is arriving and working at timer.
Cut ground wire and check circuit again.
This can narrow down ground fault problem.
Disconnect wires from timer and connect wires direct to outdoor lights.
This will tell you if timer is suspect.

List all things on same circuit breaker, and test each to find which are working.
Each electrical box is connected to next box and to next box back to circuit breaker.
Open each box and check for loose wires, signs of burning.
This will narrow down location of problem.

When working in main breaker box, the wires on main breaker have power at all times, even when main breaker is turned off. This is true unless meter is pulled. Always stand on dry boards and never lean into or touch anything else when working in main box. Do not hold screwdriver between teeth.
Tape tester leads to wood sticks to keep hands away from voltage.
Test voltage at circuit breaker. Make sure neutral and ground are attached tight on busbar. Make sure black wire is attached tight to breaker. Move black wire to another same-size circuit breaker. Disconnect ground wire and test circuit again to check if ground fault is causing problem.

Just need to verify the location of the main circuit breaker on my 1997 Harley Road King


Harley puts these things in so many places on some many different years and models of bikes that it's very difficult to keep up with. Usually on Road Kings. the main circuit breaker is under the seat or the right side cover. But, I can't swear to it.

Good Luck
Steve

Two circuits in panel inoperative


not likely check the neutrals on those circuits the chance that 7&19 are bad and everthing in between is good is almost impossible. i would check the wires very close and also inspect the neutral buss connections both main connections and circuit connections

Circuit Installation


The process contain a certain degree of risk, but if you follow all safety steps, you should be just fine. Most standard electric panels have a main disconnect switch or breaker at the top of the panel or load center. It is a code requirement. If the load center doesn't have one, then look for the main disconnect at a different location possibly near the electric meter. Turn it off. You better have a flashlight handy or a caving or miner's helmet, because you are going to need a light source. Circuit breakers plug into the load center. The electricity flows into each breaker via a large metal strip inside the panel or load center. It is called a bus bar. This strip is HIGHLY dangerous. Touch this strip while it is energized and you will very likely die. If a screwdriver you are holding slips and touches it, expect nearly the same result. Keep in mind that even though the main breaker may be off, the bus bar may be energized for any number of reasons! Also, the wires leading into the top of the main disconnect are always energized and represent a life safety hazard. In other words, the inside of an electric panel or load center is ALWAYS a dangerous place to be. The black wire to a circuit attaches to one end of a standard or AFCI breaker. The location is almost always a hole that is drilled through a threaded cylinder. A screw twists into this cylinder and tightly clamps down the wire. When installing a new breaker, I always find it easier to attach the circuit wire to the breaker before I plug the breaker into the panel. When removing a breaker, I usually unplug the breaker from the bus bar and then remove the circuit wire from the end of the breaker. Make sure the breaker is in the off position. The end of the breaker where the circuit wire attaches almost always has a small notch in it. This notch fits under or slides into a metal tab strip that runs parallel with the bus bar. This is what stabilizes the breaker. Without this secondary attachment, the breakers would flap in the panel much like a sail that is not tied down to the mast or the side of a boat. Tip the end of the breaker so the notch slides into the metal tab. You then align the breaker with the bus bar and push it down onto the bar. The tension tabs on the breaker open slightly and grip the bus bar as the breaker seats itself. If you feel the breaker seated itself correctly, simply turn it on. All should be well. Remember to follow the instructions that come with the breaker. Always follow the sequence the manufacturer suggests. AFCI breakers require one additional step. You need to locate the white wire that is paired with the black wire in that circuit. The white wire actually attaches to the breaker as well. There is a coiled white wire that leads out of the breaker. This white wire attaches to the neutral bus bar in spot that is vacated when you disconnect the white wire of the circuit. If this answer scared you, call an electrician!
