Two methods to repair car starter solenoid switch

Method 1

Starter electromagnetic switch in the maintenance process, such as found in the ignition coil on the starter solenoid switch contact piece additional resistor short-circuiting switch is damaged , the hand piece of the contact parts nor the replacement of any one model available on the old alternator ZQ diode -15 or ZQ-20 to repair. Whether or use a cathode tube cathode tube , a diode must first shell on a lead solder . As with the negative control, you need to pick cathode tube welding line shell starter solenoid switch into the field then columns , then the negative lead pipe original starter solenoid switch additional resistance short circuit switch connector column ; such as cathode tube , the connection just the opposite. But beware, the diode housing and the lead can not grounding . In this way additional resistance to repair ignition coil shorted switch contact pads on the starter solenoid switch , do not disassembly starter solenoid switch and disintegration , thus not only saving time and convenience .

Method 2

Starter solenoid switch in the maintenance process , if found to maintain sealing off or open coil grounding point when using the following simple method to fix this . Dimensionless kinds of faults are mostly holding coil grounding point Weld or false welding , so if do not have a soldering iron , you can keep the head coil Flanagan points by grounding out, cover the head with a solenoid switch down to the solenoid switch housing on or attached to the screws and tighten methods to repair. Of course , in the case with the welding conditions , or the thread welded to the core is still the best .

When a suspected faulty generator , can initially detected in the car, remove the generator without disassembly further testing. Detection tools can be used multimeter ( voltage , resistance profile ) , the general DC voltmeter , DC ammeter and oscilloscope , you can also use auto bulbs , flashlight bulbs made a small test lamps, etc., but also by changing the car working condition to detect .
