Overview

This document provides general information regarding the installation and operation of the B&C Specialty Products BC410 standby alternator for various Piper PA-32 models, including the PA-32 6X and 6XT. It details the components, pricing, and installation notes necessary for integrating the standby alternator into the aircraft. The standby system is designed to automatically activate in the event of primary alternator failure, ensuring continued power supply during flight. This document is intended for aircraft owners and maintenance personnel involved in the installation and operation of the standby alternator system.

  • The standby alternator provides 20 amps of power during primary alternator failure.
  • It activates automatically and is indicated by a panel-mounted annunciator.
  • Current loads exceeding 20 amps will cause the annunciator to flash, requiring load management by the pilot.
  • Installation requires specific Lycoming parts not included in the kit.
  • The document lists multiple PA-32 models eligible for the standby alternator installation.

System Operation

The standby alternator system provides 20 amps of power to support continued flight in case of primary alternator failure. It activates automatically when a drop in system voltage is detected, with an annunciator indicating its operation. If the current exceeds 20 amps, the annunciator will flash, signaling the pilot to reduce the load to maintain functionality.

Installation Notes

The B&C Standby Alternator is mounted on the hydraulic accessory drive pad for Lycoming dual magneto engines. For engines with separate magnetos, it is mounted on the vacuum pump drive. The installation kit does not include certain Lycoming parts, which must be purchased separately. Panel equipment includes an annunciator light, rocker switch, and circuit breakers.

Approved Models List

The document includes a list of approved Piper PA-32 models for the standby alternator installation, such as the PA-32-260, PA-32-300, PA-32R-300, and others. Each model is specified with serial number ranges for eligibility.

Safety notes

  • Ensure current loads do not exceed 20 amps to maintain standby alternator functionality.
  • Monitor the annunciator for indications of load management during flight.

Box “B” ∙ Newton, Kansas 67114 Voice: (316) 283-8000 ∙ Fax: (316) 283-7400 ∙ Web: BandC.info General Information on PA32 Standby Alternators B&C Specialty Products is pleased to announce that we have received FAA STC/PMA approval for installation of the BC410 standby alternator and matching regulator on all Piper PA32, Cherokee Six, Lance and Saratoga models (including those w/ turbocharged engines). Prices for the various components are as follows: BC410 Alternator and Regulator w/ STC (specify 14v or 28v) . . . . . . . . . $2200.00 Installation Kit (specify 14v or 28v) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $435.00 This system has been installed by Piper Aircraft as factory equipment on new PA32’s since late 2005. System Operation The standby system provides 20 amps of power to support continued flight in the event of primary alternator failure. It turns on automatically, annunciating its operation to the pilot through a panel mounted annunciator which doubles as a standby alternator load monitor. If the primary alternator fails in flight, the standby regulator will sense the drop in system voltage and automatically activate the standby alternator. If the current requirement is over 20 amps when the standby alternator is activated, the annunciator will flash. Reducing the current usage to 20 amps or less will cause the annunciator to cease flashing and light steadily. The pilot may choose which equipment is needed for the given flight conditions by simply keeping the total load below the flashing point of the annunciator. This will reserve battery energy for transient loads (such as the gear, flaps, landing lights, etc.) during approach. Loads may be beyond the flashing point of the annunciator for up to 5 minutes without damaging the standby alternator. Installation Notes The B&C Standby Alternator is mounted on the hydraulic accessory drive pad on the Lycoming “dual mag” (2-in-1 magneto) drive engines. On engines with two separate magnetos, the standby alternator is mounted on the vacuum pump drive and the vacuum pump is re-located to the hydraulic accessory drive pad. Lycoming parts needed to complete the hydraulic accessory drive are not included in the installation kit and must be purchased separately. Panel mounted equipment includes a STBY ALT ON annunciator light, a STBY ALT rocker switch (purchased separately to match the existing switches) and three standard pull-type circuit breakers (1 amp, 5 amp and 40 amp). Appropriate placards are provided for each panel mounted device. The regulator is mounted in the area between the instrument panel and the firewall. PA32_Info_Rev.
