The job of the voltage regulator is to adjust the field current so the alternator output is at a constant voltage nominally 2825v. R1 and r2 is adjusted to program the desired output voltage.

Jasco voltage regulator wiring diagram. Quality aircraft accessories is the exclusive distributor for overhauled jasco alternator components. This kit includes 50 amp alternator voltage regulator over voltage control and stc documents. Figure 21 alternator simplified electrical diagram 2 1 figure 22 stator wiring diagram typical 2 2 figure 23 typical alternator cutaway basic components 2 3. The lm338 has an output voltage range between 12v and 30v and it can deliver output current well over 5 ampere. If a new regulator is being installed along with the alternator complete its wiring. The jasco alternator is stcd for many aircraft including the early cessna 150 172 and 175 series as well as beech model 35s with early e series continental engines.
Connect alternator to balmar regulator wiring harness as indicated in wiring diagram included on page 12. The alternators positive and ground cables should be sized according to the chart on page 3. The jasco alternator system which is manufactured by skytronics in 12 volt and 24 volt configurations is approaching its fifth decade of service on both fixed wing and rotary aircraft. 25 volts adjustable regulator using lm117. Just got an ic lm117 and 4 passive components. The alternator is good and either the wiring or the.
B the affected jasco alternators are used on various engine andor aircraft installations. Applicable to continental c 90 0 200 and 0 300 engines. A jasco alternator models 6555t 6565t 7555t 7565t and 7655t produced by skytronics incorporated are affected by this service bulletin. The remaining voltage measurements should be in the same relative relationship as those used in the sample measurements shown in figures 2 and 4. Refer to table 1 for basic reference of certificated applications. The jasco alternator kit is stcd for many aircraft including the early cessna 150 172 and 175 series as well as beech model 35s with early e series continental engines.
21112018 21112018 4 comments on jasco alternator wiring diagram use figure 2 for all 12 volt jasco alternator systems with if you have an older model regulator call for a different schematic. 611 applying safety wire 6 11 612 applying safety cable 6 11 613 installation on the aircraft gear drive 6 11. Applicable to continental c 90 0 200 and 0 300 engines. This kit includes alternator voltage regulator over voltage control and stc documents. This is the most simple voltage regulator circuit diagram in our website. Use figure 4 for all 24 volt jasco alternator systems with internal spike protection.
If more output current is being consumed than is being generated the voltage drops and the regulator increases the field voltage to keep up with the demand. Tach wire if needed and other necessary wiring. Use figure 2 for all 12 volt jasco alternator systems with internal spike protection regulator j12mmsp.
