Hello, and welcome to Home Improvement. There is also a small chance that you may find a former owner of your vehicle replaced the radio fuse with a breaker, which pops and resets due to an intermittent short that they didnt take the same, or expense, to track down. Now I am losing power to 4 circuits at once without the breakers being tripped. TSBs are often the magic bullet you need to nail an elusive ghost. Sometimes, though, a light fixture that's been working fine may suddenly develop a problem that requires diagnosis and repair. The starter relay controls the power output to the starter solenoid.

For example, if you turn on the air conditioner and the engine starts to overheat because the electric cooling fan stops working, the high-amp load created by the compressor clutch may be robbing power from a power circuit shared with the fan relay. The next thing you need is a good DVOM (digital volt ohmmeter), a 12-volt test light, some fused jumper wires and possibly a logic probe (for detecting digital signals in low-voltage circuits). It happens when the relay cant send out the full signal. Yet, this important component is often overlooked until it no longer works. Toggle Comment visibility. Breakers contain a heat-sensitive bimetal contact arm and contact points to open a circuit if it overloads.
