Checking and Replacing Voltage Regulator
Skill level:
LSR-M, A&P
Tools:
Philips screw driver
Parts:
Replacement Key West Regulator
Task Description:
The voltage regulator is attached to the side of the Hot Box as shown below. It can be tested
using the procedure below.
1.
!
Remove RED wire from the Hot Box end, not the regulator end, and connect an
extension that will allow you to measure the voltage while the engine is running.
2.
!
Secure aircraft so it will not move when engine is running slightly above idle.
3.
!
Start engine, warm up until it will idle smoothly at around 2000 rpm.
4.
!
Using a volt meter, measure the DC voltage between the red lead you just removed
from the Hot Box and ground (which can be the case of the Hot Box). If 12-14 VDC is
present, regulator is functioning.
5.
!
If no voltage is present, or the voltage is lower than 12 volts, measure the “AC” voltage
being provided by the engine. This is done by measuring the voltage between the two
yellow wires going to the regulator. Note! This is AC, not DC current.
