The scooter does not start from the starter - reasons and methods for solving the problem
A common problem is that a scooter or moped starts with a kickstarter, but refuses to start with an electric starter. Let's consider all possible causes and methods for eliminating them. There may be several reasons why a scooter or moped does not start from the starter, both individually and in combination. Let's look at each of them:
Electric starter does not work
The scooter will not start from the starter if the electric starter itself is faulty. Everything is simple here. If the battery is serviceable and charged, the entire electrical circuit works, but when you press the starter button, only a click of the relay is heard, most likely the electric starter is faulty, or the contacts have come loose (oxidized).
It is very easy to check if the starter is working properly. Apply voltage to it directly from the battery, bypassing the starter relay. If the starter turns, then it is normal.
Starter relay does not work
The scooter will not start from the starter if the starter relay is not working. A faulty starter relay cannot start the starter, here everything is also simple and clear. If you do not hear the relay click when you press the starter button, it may be faulty. The relay needs to be replaced.
Starter button doesn't work
A failed electric starter button cannot close the circuit and supply power to the relay and starter, respectively. The button needs to be replaced. Sometimes wd-40 helps.
Brake contact (toad) does not work
As you know, modern scooters cannot be started from an electric starter without pressing the handle of one of the brakes. Each brake lever is equipped with a closing contact that turns on the brake light during braking. It is also responsible for closing the circuit to the electric starter.
Make sure that when you press the brake handle, the brake light is activated.
Contacts have come loose or oxidized
The starter contacts, as well as the starter relay chip, could have oxidized or come off. Inspect the contacts carefully and the quality of their connections. Make sure there is no oxide on the contacts.
Bendix doesn't work
If, when you try to start the scooter with an electric starter, the electric starter itself rotates and does not engage with the crankshaft, most likely the bendix has failed.
Dead battery
The scooter will not start from the starter if the battery is dead. A dead battery cannot crank the crankshaft with the proper force. Sometimes, when the battery is dead, the bendix does not transmit force to the crankshaft and we simply hear the starter twisting, as happens with a faulty bendix. Make sure the battery is charged.
The battery has failed
Over time, the battery capacity decreases, especially when used year-round. Such a battery, even if fully charged, instantly loses capacity under load. Even a fully charged battery, when trying to start it with the starter, can reduce the voltage to 6-8 volts. Starting the scooter with an electric starter in this situation will not work. The battery needs to be replaced.
Fuse blown
The fuse located near the battery could simply have blown.
If the turn signals, brake light and horn work, then everything is in order. If not, change the fuse.
Crankshaft seals are leaking
Check the crankshaft seals. If at least one of them shows signs of leaks, starting the scooter from the starter, especially when cold, will be problematic. Leaky seals need to be replaced.
Low compression
The most common reason for owners of scooters and mopeds to visit a workshop is that the scooter will not start from the starter, although all the electrics and battery are in order.
There is one rule, it’s better to remember - if the scooter starts normally with a kick starter, but doesn’t want to start with an electric starter, although the starter cranks the crankshaft perfectly and with sufficient force, the fault will almost always be low compression.
What does it mean? Most likely, your piston is already running out and you will need to change the piston with rings at best.
At the same time, question number two always arises - why does the scooter start from kickstarter? The answer is that when we rotate the kickstarter with our foot, especially when it is sharp, we turn the crankshaft faster.
A simple and understandable example can be given - remember the old pump with which you wanted to inflate the inner tube of your bicycle or scooter. Often these pumps do not have a sealed cuff that does not fit tightly enough to the walls. If you tried to slowly pump the chamber, all the air simply passed through the leaks in the cuff. And if you pumped quickly and with good effort, everything worked out. It’s the same here.

Checking the starter
Without removing the starter from the engine, we look for the power terminal on its body and disconnect the wire from it. We remove the battery (charged) from the scooter, look for it, ask someone for it, or buy two pieces of thick copper wire. Connect the wires to the battery terminals. Then, we apply the wire coming from the negative terminal of the battery to the starter housing, and the second wire - coming from the positive terminal of the battery - is applied to the starter power terminal
- If the starter works, then it is fully operational and the cause of the problem must be looked for in the relay, start button or wires supplying power to it
- If the starter does not work, then the fault lies in itself and it needs to be removed, disassembled and checked. It is quite possible that it can still be repaired and save a lot of money

ELECTRONICS OF ALPHA AND DELTA MOPEDS
Due to the fact that more and more owners of devices with engines of the 139FMB type and lights at recess are faced with six-coil generators (replacing the motor or preferably a more powerful generator), there is a need to write this article. First, let's figure out what the differences are. The picture shows a diagram

The “Delta”, “Alpha”, “Leader” and “Mustang” mopeds use a 12 V battery with a capacity of 2.5, 3.0 or 5.0 A/h (Table 6.1). Inside the case, the battery is filled with a chemical reagent and electrolyte. Battery maintenance involves periodically checking the level and density of the electrolyte.
The source of electricity for mopeds is a generator (magneto), the rotor of which is mounted on the left axle of the engine crankshaft. Flywheel type generator, alternating current, with excitation from permanent magnets. To diagnose a generator, special equipment is required. Disassembly
One of the main elements of the moped's electrical system is the voltage regulator-rectifier. The appearance of the voltage regulator-rectifier is shown in Fig. Rice. 6.6. The voltage regulator-rectifier performs two functions: it ensures the voltage in the moped network within the range of 12.0-14.5

Spark plugs (Fig. 6.11) recommended by the manufacturer for A7TC or A7RTC SX four-stroke engines. Analogues of these spark plugs are NGK C7HSA or NGK CR7HSA, Champion Z9Y. The technical characteristics of the spark plug are given in table. 6.9. The gap between the spark plug electrodes should be 0.6-0.7 mm. Regulatory replacement
The electromagnetic sensor of the ignition system (Fig. 6.12) is located on the stator mounting plate in the left engine cover. Checking the electromagnetic sensor of the ignition system You can test the electromagnetic sensor of the ignition system without removing it from the engine; for this you need to: measure
The starting system includes the starter, starter relay and starter drive. The appearance of the starter is shown in Fig. 6.13. The starter is a mixed-excitation DC electric motor and is designed to start the engine. On mopeds “Alpha”, “Delta”, “Leader”, “Mustang”, etc. can be installed
The starter is removed in the following order: placing the moped on a flat surface, disconnect the “-” terminal from the battery; disconnect the terminal wire from the starter (Fig. 6.17); Unclench the spring ring lock with pliers and remove the starter sprocket along with the chain from the splines (Fig.

Why is the pipe shit?
I disassembled my relay, unwinded the entire winding, re-wound it, cleaned the contacts, and now for the 5th year everything has been fine with the relay, my brain doesn’t work at all, there’s just no point in buying a new one, because there’s no guarantee of how long it will last enough again...

Where is the starter on a scooter?
Finding a starter on a scooter engine is very simple: remove the front plastic hood of the engine and the seat tank, inspect the engine and find a small cylindrical part on it (approximately the same as in the photo) located perpendicular to the longitudinal axis of the engine to which a thick power wire fits - this will be the starter.
On most scooter models, the starter is mounted at the top of the engine, just behind the cylinder. In rare cases, the starter is installed at the front or bottom of the engine.
