The most important and most complicated part of a motorcycle is this part. I teach you to know it today.

Ask the motorcycle which is the most critical and complicated part. Maybe someone says it is an engine. The engine is a system, not a component! Some people may say that the clutch, this is really not. Some people may say that it is a gear set, which is not a good idea. So which one is worth it?

I think the most critical and complicated part, if it is a carburetor car, it is the igniter! If it is an EFI car, it is the ECU! Today we come to know the igniter and teach you how to replace and identify its lines. Today we mainly talk about the most common igniters used in Honda and misbranded cars, mainly AC igniters and DC igniters. The two types of igniters mainly have three kinds of interfaces, which are two-port, double-round and single-port, and the two-port can put up to 7 lines, but generally there are at most 6 lines and 5 lines; You can put 6 lines, but generally put 4 lines and 5 lines.

No matter which interface, no matter how many lines, it must have the following functions: trigger line, high voltage line, grounding line and power supply line. The power supply line comes from the AC coil, called AC igniter, and the power supply line comes from the battery. , called DC igniter. In addition to the above four main functional lines, some may have a flameout line and a speed line. When replacing the igniter, in addition to the original car igniter can be docked according to the line color, generally need to be docked according to the function line, then how to judge the function of each line?

Below, I will teach you how to use a multimeter to judge each function line.

The common AC igniter has 5 wires, which are charging, triggering, grounding, ignition coil and flameout. Some cars will trigger the signal negatively into the igniter, which will become 6 wires. The DC igniter is a 12 volt DC power source that is charged by internal oscillation to charge the capacitor. The control of the 12 volt power supply can control the flameout, so there is no flameout line.

In the actual maintenance, using the resistance of the multimeter to measure the resistance between the five wires on the igniter butt plug, the function of each lead can be quickly identified. First determine the ground wire, the ground wire and the battery negative or the shell's resistance is zero (multimeter resistance file R * 1 file), if not found, the ground wire has an open circuit. Next, measure the resistance of each line to ground, the resistance value is 300~600 ohms for the charging coil, the resistance value is 120~200 ohms is the trigger coil, and the resistance value is a few ohms for the ignition coil primary. It is the flameout line, and the resistance to ground is infinite when the switch is turned on. The 6-line trigger signal line is two, which are not connected to the ground line.

When troubleshooting high-voltage, non-fire faults, the fault can be quickly locked by measurement. If the measurement is normal and the secondary resistance of the ignition coil is also normal, the igniter is damaged. The function of each lead is clearly identified, and when the accessory is missing in the maintenance, the replacement between the igniters can be realized. Common models and common igniters, in fact, regardless of the interface is consistent, as long as the function line is judged, according to the function docking, basically can be used. Therefore, the so-called universal igniter is also on the market. This is actually the most common Honda igniter, but Honda has the most cars, so it seems to be omnipotent.

The above is mainly Honda cars and miscellaneous brands, because they are basically short boss models, so the igniter is basically universal, but if you encounter special models, such as negative trigger, long boss, double boss, etc. The igniter is caught in the model. In general, Yamaha cars (construction, Lin Hai, etc.) and Suzuki cars (Haojue, Qingqi, etc.) are all long bosses, and the above mentioned igniters are not available. The latest models of Sundiro Honda and Wuyang Honda, although they belong to the Honda system, they all use the CBF type engine, which is a double boss. The above igniter cannot be used. This needs to be distinguished.

Short boss igniter replacement is easy, but long boss and double boss igniter replacement is very difficult, it is difficult to find a suitable one, it is more difficult to find long and short bosses to eat. However, the "Taichang Zhidian" igniter developed by the National Motorcycle Maintenance Technology Club is an alternative. It is an igniter that can be used all at once. Its compatibility is very strong, its intelligence is high, and its scope of application is very wide. It is a good helper for maintenance.

Starch Glue For Paper Tube

The starch glue for paper tube is a starch adhesive made by oxidation of corn starch. It is nontoxic,tasteless, formaldehyde free, easy to operate and convenient to transport.

starch glue for paper tube


Product features:
1. High adhesive strength, low adhesive consumption, fast drying, no delamination.
2. Use our glue to make paper tube with good hardness, no brittleness, no bubble, no
crack.
3. The viscosity is stable and has good flexibility, water and moisture resist ance.
4. The ratio of powder and water is 1:2-1:3, and the cost is only 50% of the white emulsion.
Scope of application:
1. Suitable for spiral paper tube mechanical equipment.
2. It can be used for adhesive production of paper barrel, paper corner protector and paper can.
Materials :glue powder,caustic soda,Borax
1.add 25kg water(normal tempreture) into the blender,
2.Then add the glue powder(25kg),and stirring it for 5 minutes to dissolve fully.
3.Take another container,add 10kg of water,will be caustic soda, borax pour into the water,stir well,dissolve fully.
4.The caustic soda and borax solution put into the glue powder solution slowly,stirring evenly,dissolve fully,the
can be used after wait 15 minutes.
Storage considerations:
1.Storage a few days later will be a normal phenomenon of precipitation,you just need stir it again.2.In the process of storage need to cover seal,because the colloid moisture will volatilize,sometimes the glue
powder solution will become solid or Like jelly,at this time ,you can ease with a small amount of water of 0.5-1 kg of caustic soda.
