Voltage regulator check Voltage regulator The malfunctioning of the voltage regulator might cause the following problems depending on the type of fault: 1) Lighting system bulbs burn out. 2) Lighting system is not working. 3) Battery overcharges (the main fuse blows). 4) Battery not recharging. 5) Turn indicators not working. 6) Oil and fuel check [...]

FAULT 3 After checking that there are no short circuits in the system towards earthing with the engine off and the regulator connector detached, replace the reg- ulator because it is certainly inefficient, and re- place the protection fuse. Following the replacement, measure the current and the recharging voltage on the battery ends (FIG. B). The v[...]

FAULT 5 ( FIG. E) If the turn indicators do not work, proceed as follows: - Remove the regulator connector, and insert the tester probes between the contact 5 (yellow-red) and the ground lead. - Turn the key switch to ON and check that the battery is getting voltage. If no voltage is detected, check the wiring and the contacts on the key switch and[...]
