Circuit Board Testers

Even if you don t have an electrical schematic of the circuit board which would identify components and give you the voltage and resistor values that should be present many circuit boards have test points that are clearly labeled.

Circuit board testers.

A test of circuit board components such as capacitors resistors transistors and integrated circuits can be done to some extent without removing the components from the circuit board. Multimeters can be valuable troubleshooting tools when working with circuit boards. Atwood ac gas test adapter dinosaur. Ignition control circuit board dinosaur uib s post.

Astroai digital multimeter with ohm volt amp and diode voltage tester meter dual fused for anti burn 4 6 out of 5 stars 6 745. Resistors manage the flow of current through the circuit board. Disconnect the power supply from the circuit board. They attenuate the voltage so that it is proportionate to the current.

Test the resistance points. More comprehensive testing can be performed on these components when the component is removed. Ignition control circuit board dinosaur uib s. Follow the signal path on the board so that you can locate the first resistor in the chain.
