The charger UZS-P-6/12-6.3 UHL 3.1 “Rassvet-2” is designed for charging car and motorcycle batteries with a voltage of 6 and 12 volts and a capacity of 40-75 Ah in both manual and automatic modes.
The current strength is smoothly adjustable from 0.1 to 6.3 Amperes. Moreover, the device is capable of operating at temperatures as low as -10°. In addition, “Rassvet-2” allows you to determine the degree of charge of the battery, the serviceability of the battery, and the polarity of the terminals if there are no markings on them.
The charger was produced according to TU 3-42Ts-86 “UZS-P-6/12-6.3 UHL 3.1 charger “RASSVET-2″” dated 12/01/1986.
Do-it-yourself repair of the Rassvet charger
Although the Dawn charger model KM-14 was produced back in the 80s, it is still used by some car owners to charge the battery.
This device was brought in for repair several times, so I decided to write a short article with a photo and a voltage table, maybe it will be useful to someone.
The charger (charger) is universal. It can charge 12V and 6V batteries, and also has a stabilized 12V and 9V output for powering various radio equipment.
Radio equipment with a supply voltage of 9V in the absence of power for the charger
220V can be powered from a 12V battery through a charger. To do this, you need to connect the charger to the battery with probes, and take a stabilized 9V from the socket (9V).

Repair of the Rassvet charger
Several times it was necessary to change the output transistor V1 KT803A in this device. Can be replaced with KT808A.
A couple of times I had to change the V3 MP26A transistor. Maybe MP25A.
I don’t even write about the broken ammeter and torn off crocodile clips.
