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.
