How can we check the starter's external wiring circuit for volt drop?

For voltage drop checking on the wire from the battery positive post to the starter main terminal, you place the voltmeter reading on the 1 to 3 volt range, (or what lower range you have). You then place one voltmeter lead on the positive battery post, the other lead you place on the starter positive terminal and have someone crank the engine. While the engine is cranking, you observe the voltage drop. It should be less than a volt. This seems strange because you would think the cable would not drop voltage but it sure can. If the battery post is dirty or bad connection, you could see a voltage drop all the way to the maximum 12 volts battery voltage depending upon the connection. Also you can check the return path the same way--- Negative case of the starter to the negative post on the battery for voltage drop. If it is more than a volt or two, you have a bad ground return circuit.

How do you fix no brakes light in a gs300 Lexus?
Lexus GS300 Brake Light Bulb Troubleshooting (check in this order): · Check Fuse(s) · Check Brake Bulbs - Including bad bulbs, loose connected or incorrectly installed bulbs, left, right and center high mount - 1 bad bulb or connection in the circuit can cause the entire circuit to malfunction. · Check Turn Signal Bulbs · Check switch on brake pedal · Check license plate light bulb and wiring (sometimes on same circuit) · Check trailer hitch wiring harness (sometimes on same circuit) · Check all wiring harnesses and wiring for shorts Most likely it's the fuse or a burnt bulb breaking the circuit. Sometimes the license plate and/or the trailer hitch is wired into other circuits and can cause issues in other areas. Sometimes its wires grounding out somewhere on the vehicle. See sources and related links below for bulb information. See owner's manual for location and identification of fuses.

What is the function of a fuse in household wiring?
A fuse in any type of electrical/electronics circuit is there to protect the circuit or device attached in the event that the current draw exceeds safe or recommended levels. In house wiring, the chances of the wiring becoming overheated and possibly starting a fire could be the result of something using more current than what the wire is capable of handling. Fuses and circuit breakers are an excellent idea and you should never (nope...never) run a household circuit without one. If you don't know what size of circuit breaker (or fuse) you need, you can check with your local electrical parts supplier and get the info. Or chances are very good that you can also find that information on the internet. Just check more than one site though because the accuracy may not be completely dependable.
