Engine charging and starting system Toyota Dyna (100/150)

Disassembling the starter
1. Remove the starter stator and armature assembly. After unscrewing the nut, disconnect the wire from the starter traction relay terminal. Remove the two tightening (through) bolts and remove the stator together with...

Checking the starter
Anchor 1. Check for a short circuit between the armature winding sections by measuring the resistance between the commutator plates. If there is a short circuit between the plates, replace the armature. 1.0 kW starter...

Assembling the starter
Note: When assembling the starter, use high temperature bearing grease. 1. Insert the anchor into the stator, having first applied a layer of grease to the anchor bearings. 2. Install the brush holders on the anchor;...

Determining the performance characteristics of a starter
Warning: These tests must be performed for 3-5 seconds to avoid overheating and burning of the stator winding. 1. Perform tests on the pull-in relay. a) Disconnect the stator winding wire from terminal "C". b) Connect...

Precautions — Charging System
1. Check that the battery wires are connected correctly to the generator terminals. 2. Disconnect the wires from the battery terminals when fast charging the battery. 3. Do not use a tester with high resistance (high...

Troubleshooting — Charging System
Generator Wiring Diagram. Standard Equipment (with mechanical voltage regulator).

Checking the charging system on the engine
1. Check the density of the electrolyte in each section of the battery. The density of the electrolyte of a fully charged battery at 20°C is 1.25-1.27 g/cm³ Check the electrolyte level and add distilled water if...

Disassembling a standard generator
1. Remove the generator drive side cover and remove the rotor assembly from the stator. Unscrew the three screws of the generator cover, then use a screwdriver to separate the cover and remove it together with the...

Checking the standard generator
Rotor 1. Using an ohmmeter, measure the resistance between the collector contact rings. Resistance value for a generator without an electronic regulator (in a cold state) should be within the range of 3.9 Ohms to 4.1...

Assembly of a standard generator
1. Install the rectifier unit on the stator. Holding the terminals of the rectifier block with round-nose pliers, solder the wires of the stator winding to the terminals of the block. Warning: Protect the rectifier...

High speed compact generator
Note: For U series engines, two types of such generators are used: type 1, designed for a working current of 40A and 45A, and type 2, designed for a working current of 60A and 70A.

Disassembling a high-speed compact generator
1. Remove the rear cover of the generator. Unscrew the nut and remove the terminal insulator. Unscrew the three bolts (nuts for generator models 55A, 60A, 70A) and remove the rear cover of the generator. 2. Remove the...

Checking and repairing high-speed compact generator
Rotor 1. Using an ohmmeter, measure the resistance between the collector contact rings. Resistance (in a cold state) should be from - 2.8 Ohm to 3.0 Ohm If the excitation winding is open (resistance tends to infinity),...

Generator assembly
1. Assemble the generator drive side cover, rotor and generator rear cover (from the rectifier block side). a) Using a press, press the rotor together with the wave lock washer into the rear cover of the generator. b)...

Mechanical voltage regulator
Location: In the engine compartment, on the left wing mudguard. Checking the voltage regulator 1. Remove the voltage regulator cover. 2. Check for signs of burning or damage on the contact surfaces. Replace the...

Main Ignition Relay
Location: under the instrument panel on the relay block. 1. Check the relay circuits. a) Measure the resistance between terminals 1 and 3, making sure there is conductivity between them (the resistance should be low,...
