What should I do if my alternator fuse keeps burning?
Old mechanic secret: get a high-beam bulb and some wires and plug it into the blowing fuse socket. If we assume that the alternator is okay and the battery is charged up, the alt will be drawing way under 7.5 amps and the typical 5 amp high beam bulb will be quite dim.

Where are the fuses on a Honda Accord?
Turn the ignition switch to LOCK (0). Make sure the headlights and all other accessories are off. Remove the cover from the fuse box. Check each of the large fuses in the under-hood fuse box by looking through the top at the wire inside. Removing these fuses requires a Phillips-head screwdriver.
What should I do if my alternator keeps dying?
The alternator is essentially a generator and it keeps your battery charged while supplying additional electrical power for the other systems in the vehicle. If you have a new alternator and your battery keeps dying on you, then there’s definitely a problem that you’re going to need to look into.
What happens if you have a new alternator and the battery is not charging?
The alternator in your car is an integral part of your vehicle’s electrical system. If you have a new alternator and the battery is still not charging, then you definitely have some kind of a problem with your battery that you’ll need to address immediately.
How can I tell if my alternator is working or not?
If you’re not 100% sure, you can use a multimeter, or a voltmeter, to check the current coming from your battery. Attach the positive lead to the positive battery terminal, that’s the red one, and then the negative leave it to the black terminal. With the engine off you should be getting a reading of 12.5 volts on your multimeter.
What causes an alternator to stop working on a car?
Once the alternator stops working, so do all of the electrical systems required to keep a car going. Other problems can also cause a car to not start. It could be a bad starter, corroded cables, or a broken connection somewhere between the battery and starter.
What to do if your alternator has low voltage?
Put the black multimeter probe on the negative battery terminal (if possible dig it into the battery post, not the terminal). Put the red probe on the alternator case. Your looking for the voltage to be below about 0.5v. If the voltage is higher than that examine all the negative cabling for problems. Preform the same test with the positive side.
Can a bad battery cause an alternator to over charge?
Make sure that all the connections to the alternator, remote voltage regulator (if applicable) and battery are clean, tight and in good condition. Check your battery or have it tested at your local auto parts store. A bad battery cell can cause the alternator to over-charge the good battery cells.
Why does my Alt fuse keep blowing out?
I covered the bare metal under it with rubber to ensure that I wouldn’t ground, then screwed a nut and washer ON TOP of the wire, instead of the normal setup which is nut, wire, nut+washer (broken post).
Where does the battery go in a Honda alternator?
Battery (B) — This terminal/wire goes directly to the battery to recharge it. This is the output from the alternator. The ring terminal connects to a stud on the back of the alternator. All the other connections are in a plastic connector. Lamp (L) — Honda has used two different methods of illuminating the charge warning indicator lamp.
How often do Honda alternators need to be replaced?
If you don’t know how the Honda alternator and charging systems work in your particular vehicle, it’s very easy to misdiagnose it and falsely conclude that the alternator has failed. Thousands of perfectly good Honda alternators are replaced each year. Let’s take a look at the different generations and how they work so you can avoid a misdiagnosis
What is the warning light on a Honda alternator?
The third controls the warning light (white wire with a blue stripe). The fourth is the charging rate input to the ECM (the blue or yellow wire).The fifth is an output from the ECM (white with a yellow stripe).This is the control circuit that turns the alternator on through the voltage regulator.
What are the three circuits in a Honda alternator?
These three circuits are: The ELD input (Electric Load Detection),the FR input (Charging Rate Signal),and the C circuit output (The wire that the computer uses to turn the alternator on.). The first of the inputs is the ELD or the electric load detection sensor. This sensor monitors the electrical load on certain circuits.
How many wires are involved in a Honda Charger?
The fourth is the charging rate input to the ECM (the blue or yellow wire).The fifth is an output from the ECM (white with a yellow stripe).This is the control circuit that turns the alternator on through the voltage regulator. There are a total of three wires to the computer that are involved in the charging system.
How does the computer turn off the alternator?
When this happens, the computer can turn off the alternator through the one computer output, the C circuit (white wire with a yellow stripe).This is the one circuit where the computer turns the alternator on and off. The voltage regulator supplies an 8.5 volt (approximate) reference signal to the computer.
