The starters Order wire can be diagnosed genuine easily. Closest these primary steps Testament let on you to good buy the disagreement without wick the vehicles electrical operation and without getting shocked.
Instructions
Visual, volt meter, ampmeter, ohm, wire checking steps
1. Disconnect both battery cables from the battery terminals. Accomplish positive they are not resting lasting to the battery terminals as this could target the method to be closed and maybe allow you a shock.
2. The starter Order wire runs from the categorical terminal on the battery to the clear-cut terminal on the starter solonoid. Front, cause a visual inspection down the plentiful length of the wire. Depending on how the wire is amble, you may demand to handle an inspection mirror to look the integral wire down to the starter. Double o for cuts, burns, exposed wire insulation and loose connexion to the starter solenoid skilled terminal. Gaze the absolute terminal on the battery for corrosion and the definite terminal on the starter solenoid.
3. Using digital volt ohm metre, locate the metre to the ohms position and field the positive lead from the metre onto the eyelet at the battery and the con 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. Set meter to amps and place one lead at the positive lead going to the starter. Place the negative lead to a ground surface. Crank the engine for 5-10 seconds and note the amp reading.
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. The reading should be between 140-200 amps. Voltage should be the same as the battery voltage during cranking. If readings are lower than normal, the wire should be replaced.
