Cessna C182 G1000 Skylane Installation Example
Cessna 182 Skylane · Wiring Diagram
Overview
This document provides an installation example for the BatteryMINDer® Maintenance Charger specifically for the Cessna 182 Skylane equipped with the G1000 avionics system. It outlines the necessary steps to connect the charger harness kit (BM-AIK1 or BM-AIK2) to the aircraft's electrical system, emphasizing the importance of following the kit instructions thoroughly. The installation involves accessing the battery box and Power Junction Box, making specific connections to the battery relay and airframe ground, and ensuring proper testing and documentation of the installation. This guide is intended for maintenance personnel and technicians familiar with Cessna aircraft systems.
- The installation is specific to the Cessna 182 Skylane with G1000 avionics.
- The charger harness connects to the battery relay and an airframe ground, not directly to the battery.
- Key steps include accessing the battery box and Power Junction Box, and verifying connections for safety.
- Proper voltage and polarity testing at the SB50 plug is crucial before reattaching battery cables.
- Documentation of the installation in the maintenance logbook is required.

Installation Steps
The document details a step-by-step process for installing the BatteryMINDer Maintenance Charger. Key steps include removing the rear baggage compartment panel to access the battery box, disconnecting battery cables, and removing the left side cowling to access the Power Junction Box. The installation requires assembling a charger connection cable, connecting it to the battery relay and airframe ground, and ensuring proper voltage and polarity testing.
Wiring Connections
Specific wiring connections are outlined, including attaching the positive terminal of the cable assembly to the left side relay contactor and the negative terminal to an airframe ground. The document emphasizes verifying continuity between the SB50 positive lug and the positive battery cable.
Final Steps and Testing
After completing the wiring, the document instructs to reattach battery cables, test for proper voltage at the SB50 plug, and document the installation in the airframe maintenance logbook as a minor alteration. It also includes guidance on securing the SB50 plug and replacing covers.
Safety notes
- Ensure all electrical connections are secure to prevent short circuits.
- Verify proper voltage and polarity before reattaching battery cables.

Please read the instructions with the kit completely before referring to this example. The kit instructions call for connecting to the battery relay and an airframe ground, instead of directly to the battery. The relay and airframe ground are readily accessible in the Skylane at the Power Junction Box inside the left cowling where the external power receptacle is located. The exact configuration of your aircraft may vary from this example and require variations from these instructions. 1) Remove the close out panel from the rear baggage compartment to access the battery box. Disconnect the battery cables. 2) Remove the engine left side cowling. 3) Remove the cover from the Power Junction Box. 4) Assemble charger connection cable from the parts kit. Connect the fuse holder assembly to the positive side of the Anderson SB50 plug and add wire for a length of about 16”. Use the fiberglass sleeving to protect and terminate with one of the large ring terminals. Similarly, connect about 10” of ground wire, add protective sleeving, and terminate with ring terminal. 5) Temporarily attach the red SB50 plug to the front side of the external power receptacle to hold in position while connecting the harness. 6) Attach the positive terminal of the cable assembly to the left side relay contactor. Verify continuity between SB50 positive lug and the positive battery cable. 7) Attach the negative terminal of the cable assembly to a convenient airframe ground, such as the lug on the left side of the Power Junction Box where the braided airframe ground strap is attached under the external power receptacle. 8) With harness wired to battery relay and airframe ground, attach dust cover and secure the SB50 plug to the external power receptacle with spacers and a hose clamp. 9) Reattach battery cables and test for proper voltage and polarity at the SB50 plug with aircraft power OFF. 10) Install elastomeric dust cover on SB50 plug and label “MAINTENANCE CHARGER”. 11) Replace both covers to the Power Junction Box. 12) Replace battery box cover and rear closeout panel. Maintenance charger harness connections at Power Junction Box Power Junction Box covers re-installed and dust cover attached. Space SB50 plug approximately .15” to provide clearance for dust cover. Use hose clamp to secure plug to external power receptacle. FUSE HOLDER BATTERY CABLE POSITIVE LUG AIRFRAME GROUND LUG Finished installation. BatteryMINDer plug adapter connects through the external power opening in the LH cowling. 13) Perform cockpit electrical system test for normal operation. 14) Make appropriate entry in airframe maintenance logbook to document installation as minor alteration and return to service.
