Now you can replace your heavy, worn out generator or unreliable alternator with a dependable lightweight Alternator system — with NO expensive requirement to relocate your oil cooler! Approved for Lycoming-powered JC5 thru PA22 aircraft in both the “Standard” and “Restricted” categories, the BC400-2 Alternator weighs 6.1 lbs., and features the same “no-compromises” design and construction that has been our hallmark since 1980 — a precision-balanced rotor; sealed heavy-duty ball-bearings; three solid attachment points; two built-in cooling fans; and provision for aircraft-style, external regulation. The BC201-1 Controller (Regulator) features solid-state construction, with “quiet” linear voltage regulation; integral over-voltage protection; low-voltage sensing and warning; and field-adjustable charging voltage.
The BC400 installation kits include a Boss (Wide Deck) or Case (Narrow Deck) alternator mounting bracket, attachment hardware, belt tension arm, high-performance belt, field connector assembly, and panel-mount warning light. An optional “electrical package” adds necessary wire and ring terminals, circuit breakers, and a Mil-Spec “OFF-ON” toggle switch (useful for early aircraft requiring an “upgrade” of existing electrical components). Note: this approved installation is applicable to aircraft with previously-existing electrical systems only.
