Check (Dc) Circuit Breaker; Check Bridge Diode; Check 12Vdc Coil - Briggs & Stratton CE8070 Troubleshooting Manual

Hand-Held Series Generators • Familiarization & Troubleshooting Guide
Section 3 • Troubleshooting
Test C: - Check (DC) Circuit Breaker
•• Step 1:
• Remove the three screws that secure the control panel
to the face of the generator unit.
•• Step 2:
• Remove both the terminals at the back of the circuit
breaker (Figure 22A).
•• Step 3:
• With the circuit breaker ON and your VOM set to
ohms, check for continuity at the terminals of the
circuit breaker (Figure 22B).
Figure 22 — Checking (DC) Circuit Breaker
A
- Continuity = Circuit Breaker OK
- No Continuity = Defective Circuit Breaker.
Replace Circuit Breaker
Test D: - Check Bridge Diode
With the control panel still removed:
•• Step 1:
• Locate and separate the harness connector that has the
two brown wires. Push the male half of the connector
aside.
NOTE:
You must follow the Diode Test
instructions that are provided with the meter you are
using.
•• Step 2:
• Using the female terminals of the brown wires and the
positive output terminal of the cigarette lighter, or the
DC receptacle, you can check continuity of the bridge
diode wiring (Figure 23).

Test E: - Check 12VDC Coil
With the control panel still removed:
•• Step 1:
• Locate and separate the harness connector that has the
two brown wires coming.from the stator.
•• Step 2:
• With your VOM set to ohms, read the coil resistance
at the terminal of the brown leads in the connector
(Figure 24).

•• Step 3:
• Compare readings with resistance values in the
apppendix.
Test F: - Check Rotor Winding
