Problem: Magneto overcharges Condition Remedy 1. Internal battery short circuited 1. Replace battery 2. Regulator/rectifier resistor damaged - defective 2. Replace resistor 3. Regulator/rectifier poorly grounded 3. Clean - tighten ground connection Problem: Charging unstable Condition Remedy 1. Lead wire intermittently shorting 1. Replace lead wire 2. Magneto internally shorted 2. Replace magneto 3. Regulator/rectifier defective 3. Replace regulator/rectifier Problem: Starter button not effective Condition Remedy 1. Battery charge low 1. Charge - replace battery 2. Switch contacts defective 2. Replace switch 3. Starter motor brushes not seating 3. Replace starter motor 4. Starter relay defective 4. Replace relay 5. Emergency stop - ignition switch off 5. Turn on switches 6. Wiring connections loose - disconnected 6. Connect - tighten - repair connections Problem: Battery "sulfation" (Acidic white powdery substance or spots on surfaces of cell plates) Condition Remedy 1. Charging rate too low - too high 1. Replace battery 2. Battery electrolyte insufficient 2. Keep electrolyte to prescribed level 3. Specific gravity too low 3. Charge battery - add distilled water 4. Battery run-down - damaged 4. Replace battery 5. Electrolyte contaminated 5. Replace battery Problem: Battery discharges too rapidly Condition Remedy 1. Electrolyte contaminated 1. Replace battery 2. Specific gravity too low 2. Charge battery - add distilled water 3. Charging system not charging 3. Check magneto - regulator/rectifier - circuit connections 4. Cell plates overcharged - damaged 4. Replace battery - correct charging system 5. Battery short-circuited 5. Replace battery 6. Specific gravity too low 6. Charge battery Problem: Battery polarity reversed Condition Remedy 1. Battery incorrectly connected 1. Reverse connections - replace battery - repair damage 5-14
