Maintenance Instructions for the JASCO Alternator System

Compared to the best generator, the JASCO Alternator is lighter, more reliable, delivers more power, and requires less maintenance. In addition, you can extend the life of your JASCO charging systems by following these basic maintenance instructions.

1. Inspect ram air inlet for obstructions prior to flight as part of your walk around.

2. Remove gear driven alternators every 250 hours and inspect rubber drive gear bushings for alignment, wear, or deformity. If damage is discovered, these inexpensive parts can be purchased from Skytronics to extend the life of your charging system.

3. Minor adjustment of system charging and voltage can be accomplished by adjusting the regulator variable resistor, located under the white protective cap on your JASCO Regulator. The variable resistor is very sensitive and requires only slight adjustment to bring system voltage to required levels. Your JASCO charging system is factory set, and should require no adjustment out of the box.

4. For abnormal operation including blown circuit breakers, failed fuses, erratic charging, no output or over voltage problems, contact the Skytronics, Inc. service department. We offer FREE factory evaluation including bench check of both alternator and regulator. In addition, our factory repair of your JASCO charging system carries the same warranty as a new system.
