Voltage Regulator Check; Recharge System Voltage Check; Starter Motor - Gilera Runner RSTPurejet Service Manual

Runner RST Purejet

Voltage regulator check

With the battery fully charged, measure the volt-
age in the battery poles with engine at high speed.
The voltage must not exceed 15.2 volt.
If higher voltage is found, replace the regulator.
At voltage less than 13 volt, proceed with checks
on the stator and relevant wiring.

Recharge system voltage check

Connect an ammeter induction clamp to the volt-
age regulator positive cable. Measure the battery
voltage and turn on the lights with the engine off
and wait until the voltage settles at around 12 volts.
Start the engine and measure the current distrib-
uted by the circuit with the lights on and engine at
high rpm.
If the current value is less than 10A, repeat the test
using a new regulator and/or stator instead.
