Voltage regulator, running check
Make sure that the connections are in compliance with the
diagram.
Remove the respective clamp from the battery positive pole.
Insert a voltmeter with direct current between the two poles of the
battery.
Connect a 20A ammeter at direct current between the positive pole
and cable 1 respective clamp.
Start a few times until the battery voltage goes down to 13 V.
When the battery voltage reaches 14.5 V, the ammeter current will
drop to a value near zero.
If the voltage is lower than 14 V and the recharge current is zero,
replace the regulator.
Note: The voltage regulator does not work when not earthed and
the battery is completely discharged.
Warning: when the engine runs, do not remove the battery cables
and do not take the key off the control board.
Do not place the regulator near heat sources, a temperature
exceeding 75° C could cause damages.
Avoid any electric welding either on the engine and on the
equipment.
