WARNING: TO PREVENT SERIOUS BURNS, AVOID WARNING: DO NOT ALLOW FLAME OR SPARKS THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. WARNING: ALWAYS REMOVE RINGS, WATCHES, TAKE OUTS The abbreviation T/O is used in the component location section to indicate a point in which the wir- ELECTROSTATIC DISCHARGE (ESD) SENSITIVE All ESD sensitive components are solid state and a symbol (Fig. 2) is used to indicate this. When han- (1) Always touch a known good ground before han- dling the part. This should be repeated while han- (2) Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. (3) When using a voltmeter, be sure to connect the ground lead first. (4) Do not remove the part from its protective packing until it is time to install the part. (5) Before removing the part from its package, ground the package to a known good ground on the DIAGNOSIS AND TESTING TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit there are several common tools necessary. These tools • Jumper Wire - This is a test wire used to con- nect two points of a circuit. It can be used to bypass WARNING: NEVER USE A JUMPER WIRE ACROSS LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. • Voltmeter - Used to check for voltage on a cir- cuit. Always connect the black lead to a known good CAUTION: Most of the electrical components used • Ohmmeter - Used to check the resistance between two points of a circuit. Low or no resistance CAUTION: - Most of the electrical components used • Probing Tools - These tools are used for probing terminals in connectors (Fig. 3).
