Identify A Vehicle Starter'S Command Wire

The starters Order wire can be diagnosed indubitable easily. Next these relevant steps Testament permit you to bonanza the dispute without poor the vehicles electrical transaction and without getting shocked.


Instructions


Visual, volt meter, ampmeter, ohm, wire checking steps


1. Disconnect both battery cables from the battery terminals. Assemble firm they are not resting quick to the battery terminals as this could basis the method to be closed and maybe administer you a shock.


Crank the engine for 5-10 seconds and note the amp reading. The reading should be between 140-200 amps. Voltage should be the same as the battery voltage during cranking. Inspect for cuts, burns, exposed wire insulation and loose connexion to the starter solenoid pleasant terminal. Examine the clear-cut terminal on the battery for corrosion and the acceptable terminal on the starter solenoid.


3. Using digital volt ohm metre, fix the metre to the ohms position and compass the certain bob from the metre onto the eyelet at the battery and the negative wire to a metal ground source. The reading should read 0 or very close to 0. If a high ohms reading exists, the wire is damaged under the insulation and should be replaced. Use the same technique to probe every few inches of the wire checking for any high ohms readings.


4. Connect both battery leads to the positive and negative terminals. Reconnect the other end of the wire to the positive terminal on the starter solenoid. Using the volt setting on the meter, touch the positive lead to the eyelet at the starter solenoid and the negative lead to a metal grounding surface. Crank the engine for 5-10 seconds. If voltage is less than 12-14 volts, either the battery is low or there is a short somewhere in the wire. Wire should be replaced.


5. Set meter to amps and place one lead at the positive lead going to the starter. Place the negative lead to a ground surface.2. The starter Order wire runs from the affirmative terminal on the battery to the positive terminal on the starter solonoid. Head, conclude a visual inspection down the comprehensive length of the wire. Depending on how the wire is dart, you may charge to practice an inspection mirror to beam the entire wire down to the starter. If readings are lower than normal, the wire should be replaced.
