Usually, the first sign that your charging system is in trouble is a “battery,” “ALT,” or “CHARGE” warning light illuminating on your instrument panel while driving. It means that for some reason, the alternator has stopped charging the battery and your car is running on battery power.

What causes the charge indicator light to come on?

You may notice: your ALT or CHARGE indicator light comes on, your engine is hard to start and cranks slowly, or doesn’t crank, your battery demands lots of water, your alternator makes noises, or your headlights suddenly go dim. These and other problems may be caused by a fault in the charging system.

How does the 79-83 Honda DOHC charging system work?

79-83 Honda DOHC charging system help The regulator/rectifier is a box that actually contains two separate devices. The regulator is what sends the power to the rotor. It turns on and off power to the rotor so the magnet turns on and off so the system can maintain 14.4 volts at the battery.

Why are my Honda CB 750 choppers not working?

If you get a reading with no wires and no reading without, then the wires are most likely your problem. INSULATION BREAKDOWN These coils have a solid metal core running through them. It is used solely for mounting. It is not a ground. Sometimes the insulation inside the coils starts to break down and the coil will short to the metal core.
