Disconnect the thermo sensor wire electrical connectors. See Figures 3 and 4 Fig. Remove the guesswork from Mazda B2000 repairs. Air Pump Relief Valve See Figure 3 11 Page 29 Fig. Have your assistant slowly raise the speed of the engine to about 2,000 rpm or until the current indicator needle stops moving, whichever comes first. Disconnect the two battery cables. Be sure that the choke plate is fully open.
I like royal p … urple and super tech the best less tight shifting in cold temps and did not like the synthetic by valvoline. Start the engine and run it at idle. I would suggest if you are considering doing this you should be mechanicall … y inclined due to the time,knowledge it requires to do this correctly. If the component comes to life, the switch has failed. When installing a battery, always connect the grounded terminal first. Remove the nozzles from the manifold by unscrewing the nuts. Connect a test light to the fuse link by attaching the ground wire on the test light to an engine bolt and touching the probe end of the light to the bottom of the fuse link wire where it splices into the alternator output wire.
Current should flow when the engine speed is between 900-4,000 -200 rpm, manual or 7,500-5,200, automatic. Slide the drive stop-ring retainer toward the armature and remove the stop-ring. This magnetic action moves a plunger which mechanically engages the starter and closes the heavy switch connecting it to the battery. A voltage regulator is wired into the current supply to the alternator to prevent it from receiving too much current which would cause it to put out too much current. Unfasten the idle switch leads. Installation is performed in the reverse order of removal. There are many possible ways in which the charging system can malfunction.
See attached link for diagram showing location. Set the ohmmeter to the X1000 scale. When an electrical current of excessive power passes through the fuse, the fuse blows the conductor melts and breaks the circuit, preventing the passage of current and protecting the components. However, you should make sure before doing this work that there are no basic maintenance problems in the secondary circuit of the system, since it is often impossible to return electrical parts. A systematic search through the fuse, connectors, switches and the component itself will almost always yield an answer. If a weak spark is still noted, proceed to step 2.
Remove the distributor from the engine. Resistance, at 68ÂºF 20ÂºC , should be 8. When the test is completed, disconnect the voltmeter and replace the regulator cover. Touch the probe end of the test light to the positive battery post. On the '87 B2000 the fuel is under the hood, on the right wheel weld. On 1979 and later models, disconnect the vacuum hose at the vacuum amplifier and the vacuum hose at the three way solenoid valve.
Install the distributor cap and connect the primary wires. Remove the air cleaner assembly from the carburetor. On 1980 and later models, the only way to test the module is to substitute a known good module in its place. A short in an automotive wiring harness can develop sufficient heat to melt the insulation on all the surrounding wires and reduce a multiple wire cable to one sad lump of plastic and copper. Do, when possible, pull on a wrench handle rather than push on it, and adjust your stance to prevent a fall.
The clearance should be 2. A fuse link fusible link or main link is a wire that acts as a fuse. You should now have a T-fitting with two hoses connected to it: one running from the top of the air control valve to the T-fitting, and the other running from the intake manifold to the T-fitting. Disconnect the wiring from the regulator. In an alternator, the field usually rotates while all the current produced passes only through the stator winding. Disconnect the air hose from the check valve. You have now established that current is getting to the component.
Disconnect the voltage regulator wiring harness connector at the voltage regulator. Working underneath the instrument panel, disconnect the lead at the back of the choke switch. If there was no power, then the problem is between the battery and the component. Inspect the wires for cracks or brittleness. Install the heat stove on the exhaust manifold.
Ground Some automotive components are grounded through their mounting points. This can be determined by feeling compression with your thumb over the spark plug port. Connect a pressure gauge between the air pump and the air control valve with a T-fitting. Install the two solenoid retaining screws and washers. Check for vacuum at the end of the hose which you disconnect in Step 1; there should be vacuum present. Likewise, keep your tools clean; a greasy wrench can slip off a bolt head, ruining the bolt and often harming your knuckles in the process. Charging System The automobile charging system provides electrical power for operation of the vehicle's ignition system, starting system and all electrical accessories.
