Charging System - Kubota GR1600EU Workshop Manual

GR1600EU, WSM

(10) Charging System

No-load Dynamo Output
1. Disconnect the lead wires from the dynamo.
2. Start the engine and operate the dynamo at the rated speed.
3. Measure the output voltage with a volt meter.
4. If the measurement is not within the specified values, replace
the dynamo.

CAUTION
• To avoid personal injury, do not touch the rotating or hot
parts while the engine is running.
NOTE
• Before performing this checking, make sure that the
no-load dynamo output is proper.
• Complete the charging circuit with fully charged battery.
1. Rum the engine at the rated speed.
2. Keeping the coupler (2) of regulator being connected, measure
the voltage with a volt meter (5) across the terminal blue "a" and
terminal blue (c). (Refer to figure (A).)
3. If the measurement is not within the specified value, replace the
wire harness between the dynamo (4) and regulator (1).
4. If the measurement is within the specified value, measure the
voltage with a volt meter (6) across the terminal red "f" and
chassis. (Refer to figure (B).)
5. If the measurement is not within specified value, replace the
regulator (1).
