Brake Warning Light Flashing

Brake Warning Light Flashing
If the brake warning light is flashing, this generally indicates that the brake fluid is slightly low.

You might not know but at the top of the brake fluid reservoir, there's a sensor that causes the brake warning light to go on whenever the brake fluid level is low. Since the brake warning light is flashing while driving for a second or so and did not stay on continuously, the brake fluid level must be just slightly low.


You probably noticed the light flashing when you drove over a dip or bump. This caused the brake fluid in the reservoir to slosh and, for a second, the fluid was not in contact with the sensor. Consequently, the warning light came on.

What to do?
Buy yourself a can of high-quality brake fluid ("DOT 3" or "DOT 4", as it's called) and carefully add just enough to top off the brake fluid reservoir. Do not leave the brake fluid reservoir open any longer than necessary. Doing so will cause the brake fluid to become contaminated by moisture in the air and this will then lead to a whole slew of new problems. Also, for the same reason, throw the can of brake fluid away when done.

How to Test an Alternator
An automobile has many electrical devices, such as the starting system, lights, radio, etc. These devices are operated by the electric current supplied from the battery and alternator. The amount of power generated depends on the alternator specification and engine speed.
