3.7 Starter motor clicks when ignition key is turned
This is a common problem where the starter will only click when the
ignition key is turned, rather than starting the motor. There are several
possible causes of this. Typically, if the battery is in good shape
and is fully charged with good connections, the starter's problem could
be caused by a bad key ignition switch, a loose, corroded, or broken
wire at the starter, a corroded solenoid plunger, a bad clutch pedal
lockout switch, or worn brushes within the starter. Typically, this
problem is caused by too-little voltage getting to the starter motor
due to age and corrosion all along the ignition system and in the ignition
and clutch pedal switches. Many Suzuki owners go for years without fixing
it, just becoming accustomed to turning the key repeatedly, clicking
several times before it'll start. Others have wasted money on new or
rebuilt starters, only to find that the problem persists. The least
expensive fix is to use the wire going from the ignition as the trigger
for a 30-amp relay going from the battery to the starter.
