Sd 7860 Alternator External Regulator Wiring Diagram
Jasco voltage regulator wiring diagram. 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. Use figure 4 for all 24 volt jasco alternator systems with internal spike protection. 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. Just got an ic lm117 and 4 passive components. R1 and r2 is adjusted to program the desired output voltage. The job of the voltage regulator is to adjust the field current so the alternator output is at a constant voltage nominally 2825v.
611 applying safety wire 6 11 612 applying safety cable 6 11 613 installation on the aircraft gear drive 6 11. B the affected jasco alternators are used on various engine andor aircraft installations. Applicable to continental c 90 0 200 and 0 300 engines. The lm338 has an output voltage range between 12v and 30v and it can deliver output current well over 5 ampere. 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. A jasco alternator models 6555t 6565t 7555t 7565t and 7655t produced by skytronics incorporated are affected by this service bulletin.
Use figure 2 for all 12 volt jasco alternator systems with internal spike protection regulator j12mmsp. 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. The alternator is good and either the wiring or the. If a new regulator is being installed along with the alternator complete its wiring. The alternators positive and ground cables should be sized according to the chart on page 3. This kit includes 50 amp alternator voltage regulator over voltage control and stc documents.
Refer to table 1 for basic reference of certificated applications. This kit includes 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. Connect alternator to balmar regulator wiring harness as indicated in wiring diagram included on page 12. 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. This is the most simple voltage regulator circuit diagram in our website.
Tach wire if needed and other necessary wiring. The remaining voltage measurements should be in the same relative relationship as those used in the sample measurements shown in figures 2 and 4. Quality aircraft accessories is the exclusive distributor for overhauled jasco alternator components.
