MOTORCYCLE DNEPR-12
The electrical equipment of a motorcycle consists of sources and consumers of electrical energy, auxiliary devices and
electrical network. It provides ignition of the working mixture in the engine cylinders, lighting, sound and light signaling.
The electrical circuit of the motorcycle is shown in Fig. 28.
Electricity sources: battery ZMT12.
DC generator G414 with relay regulator PP302.
Electricity consumers: ignition devices (ignition coil, breaker and spark plugs), lighting and alarm devices (headlight with electric lamps, motorcycle and sidecar lights, sound signal).
Auxiliary devices: central switch with ignition switch, fuse and indicator lamp (red light filter) for charging the battery; indicator lamps for the neutral position of the gear shift mechanism and turning on turns PD20G (green filter); combination switch (on the steering wheel) with a lever for turning on the high and low beam, a signal button and an ignition timing lever; direction indicator switch; contact plugs (on the gearbox); turn signal breaker relay (in the headlight); switch for high and low beam (in the headlight); socket for a portable lamp (on the frame under the driver’s seat); Brake light switch.
The electrical network, consisting of low voltage wires, is made according to a single-wire circuit, i.e., one wire is connected from sources of electrical energy to consumers (from the positive poles of the battery and generator), and the second wire is the frame and other metal parts of the motorcycle and themselves devices (“mass”). The negative poles of the battery and generator are connected to ground.

Excursion into history
It is generally accepted that the prototype of the Urals was the German motorcycle BMW R-71, the drawings of which were officially purchased in the fortieth year of the last century.
After studying and developing the technical documentation, the domestic M-72 motorcycle was born, which had some differences from the prototype:
- The model was equipped with a double-disc clutch (in German, a single-disc clutch was used);
- The final drive ratios were increased, which increased its cross-country ability in off-road conditions;
- The wiring diagram of the Ural motorcycle was chosen to be single-wire (on the German prototype it was two-wire);
- The entire electrical circuit was built on a voltage of 6V (later switched to 12 volts);
- The ignition timing for different engine operating modes was given manually.
The wiring diagram for the Urals provided for manual setting of the ignition timing
A feature of domestic motorcycles was the ease of do-it-yourself maintenance - any breakdown or malfunction could be solved in the field.
Over the course of several years, no more than 7,000 copies were produced at all enterprises that mastered the production of motorcycles:
- Moscow Motorcycle Plant (MMZ had the most massive production of the M-72);
- Gorky Motorcycle Plant (GMZ);
- (Leningrad);
- Kiev Motorcycle Plant (KMZ);
The main production of Ural heavy motorcycles was launched at the Irbit motorcycle plant, located in the Sverdlovsk region, where MMZ production equipment was evacuated at the beginning of the war.
The factory instructions describe in detail the power unit of the Ural motorcycle
For reference: The Irbit motorcycle plant, formed on the territory of the brewery in November 1941, is considered to be the ancestor of the M-72 motorcycle, called “Ural-1”. Throughout the years of its activity, its only specialization was the production of heavy motorcycles. And all the military videos featured exclusively his products.

Period 1941-1954
Having appreciated all the advantages of the motorcycle in the conditions of hostilities, it was decided to increase their production several times. In 1942 alone, the Irbit Motorcycle Plant produced almost 10,000 Ural-1 motorcycles. In the post-war years, the annual target was 20,000 motorcycles.
The first batch of motorcycles from the Ural Irbit Motor Plant entered the Red Army in February 1942
The main customers were:
- RKKA (Workers' and Peasants' Red Army, later renamed the Soviet Army);
- Law enforcement service (police);
- Consumer cooperation (in the post-war period);
- Population (did not go on sale until the mid-50s).
Motorcycle M-72 Ural model 1942
For reference: Over the two decades since its release, the motorcycle has proven its worth as a mobile vehicle, most suitable for use in off-road and urban environments.
Period 1955-1964
The wiring of the Ural motorcycle also performed well - if at first the designers had concerns about loss of contact due to possible corrosion of the metal frame, then operation showed the reliability of the single-wire electrical circuit.

However, with the release of the transitional model IMZ M-61 and, on its basis, the new Ural model M-62 (in 1961), the following were modernized:
- Transmission,
- steering;
- ignition system.
In particular, automatic ignition timing was introduced, since the motorcycle received a new power unit, and the old manual control of the timing advance did not meet the technical requirements.
The new electrical wiring for the Ural motorcycle connected into a single system:
- Battery model 3MT-12 with a voltage of 6V;
- Relay-voltage regulator model PP-31;
- Generator brand G-414;
- Distributor chopper with ignition advance system PM05;
- Ignition coil model B201.
Color diagram: Ural motorcycle wiring with symbols
In just a couple of years, Ural modifications appeared in the production program of the Irbit Motorcycle Plant:
- IMZ M-61 (transitional model for testing a new overhead valve engine);
- M-63 “Ural 2” (the frame was modernized and a new exhaust system was introduced, which made it possible to increase ground clearance);
- M-66 “Ural 3” (the wiring diagram for the Ural motorcycle was replenished with direction indicators and new side lights);
For reference: a large number of models under the Ural brand and alphanumeric indices often create confusion. For example, the wiring diagram of the Ural 4320 implies the electrical system of an off-road truck, and the wiring diagram of the Ural 5557 implies its modifications, and not one of the varieties of a heavy motorcycle.
