Flow Chart - Kenwood KSC-35S Service Manual

• About voltage write down,
VB = (B1 + voltage) – Vf (Vf ≈ 0.25Vdc)
Therefore battery voltage must consider
Vf of protected reverse connection diode.
• Battery voltage should be kept inspecting
when charge condition and on tempera-
ture stand-by condition.
