Why does my ignition warning light keep coming on?
One possibility is that the warning light wire is being earthed somewhere along its length. Check this by turning on the ignition and disconnecting the warning light wire. If the warning light stays on, the wire is earthing somewhere. Inspect the wire for any chafing against the bodywork and repair it with insulating tape.
What to do if your ignition switch fuse keeps blowing?
A simple trick to finding a short is to replace the blown fuse with a pair of spade terminals, then use small jumper wires to connect them to a twelve volt light bulb. A brake light bulb works well.
Why does my ignition light flicker at low speeds?
But the light does behave in slightly different ways depending on the type of generator fitted to your car. If your car is equipped with a dynamo it is normal for the light to flicker at idling speeds as this type of generator produces little or no current at low engine speeds. The light should extinguish when the engine speed is raised.
How does the warning light on an alternator work?
If the alternator has an external regulator, the warning light wire attaches to it in the same way as a dynamo. Again the terminal will be marked WL or IND. Some cars, however, have an alternator which uses a separate relay for the warning light circuit. In this case you should disconnect the wire from this relay.
Why does the tail light come on when ignition is on?
An expert that got 5 achievements. Check all fuses one might have blown and this could be a warning sign in the old days if you blew out the tail lights the interior light would come on and the signal indicator for which bulbs but also buy the electrical manual available from ford and search out the wiring there could be a jumped circuit
Where does the ignition warning light come from?
The wire runs from the alternator through the bulkhead and up to the warning light mounted in the dashboard. From here it runs to the ignition/starter switch. In general, if the charging system is working normally, the warning light should glow when the ignition is switched on and then extinguish when the engine is started.
What should I do if my ignition light is not working?
Clean away all traces of oil and dirt then refit the mounting bolts, making sure they are tight. Pull the ends of the old wire free and tape them up. Solder the appropriate connectors (here a tag) to the ends of your replacement wire. Use insulating tape to secure the wire to the existing loom.
