How to repair a Burned Fuse Connector

The main purpose of the electrical fuse is to protect the circuitry from damage within short lead times. A fuse is designed to break the tension in terms of stopping the flow of electrical overload or short circuit. Each vehicle has several fuses are required to obtain circuits. An electrical circuit will always fail on the highest point of resistance. Most of the time in question is the fuse box. If the power circuit, power-window system (for example) the first thing you should check is the fuse.

Types of Screwdriver

Screwdrivers are generally classified as slotted, Phillips head or Robertson (square recess) head, with all three types available with round or square shanks. Quality screwdrivers are judged by the kind of metal in the blade, the finish and amount of grinding on the tip. Material used in the handle, and bar attachment to the handle are other quality indicators.

If blade metal is poor quality, it will chip and crumble under pressure. If the tip is improperly ground and flares too much, it will rise out of the screw slot. If the blade is not attached firmly to the handle, it will eventually loosen and slip in the handle.

Types and Purpose of Micrometer

Micrometers are made in various shapes and sizes, depending upon the purpose for which they are to be used. Some micrometers are graduated to measure in thousandths of an inch and others will measure as close as ten thousandths of an inch. Others are metric and measure in hundredths of a millimeter. There are two basic types of micrometers, with two distinct jobs. One is the outside micrometer, used to measure outside dimensions and the other is the inside micrometer, used to measure inside dimensions.

Outside micrometers. Outside micrometers are widely used in the automotive field to measure such components as crankshaft journals, piston pins, and valve stems to determine if they are within serviceability specifications. Most outside micrometers have a chrome plated or enameled steel frame to resist corrosion or tarnish.

STABILIZER BAR

Jika hanya menggunakan spring yang lebih lunak untuk meningkatkan kenyamanan, maka bodi kendaraan akan cenderung miring sekali bila mobi berbelok , terkena gaya centrifugal. Pada kendaraan yang menggunakan suspensi independent gejala ini lebih besar. Oleh karena itulah untuk menguranginya ditambahkan stabilizer bar yang dipasang pada torsion bar. Disamping untuk memperkecil body roll ketika berbelok, juga berguna untuk meningkatkan traksi ban. Umumnya, pada suspensi depan, kedua ujung stabilizer dipasang pada lower suspension arm melalui rubber cushions dan linkage, kemudian bagian tengah stabilizer dikunci ke frame atau di dua titik lain melalui via rubber bushing, dan dapat berputar pada titik tersebut.
