Exec 162F Maintenance Manual
37
Section 14: Electrical System
The Electrical System of the EXEC 162F requires little maintenance if inspected properly. The three most common
problems are corrosion, vibration of connectors, and chafing of wires.
Reference prints: E31-2000, E35-2000, E35-2001
SERVICE NOTES:
1. Replace the battery when it will not take or hold a charge. Check acid level periodically to insure battery plates are
covered. Keep terminal posts clean and free from corrosion and dirt.
2. The digital display monitor, engine control units (ECUs), ignition modules, and man/baro pressure sensors are NOT
user serviceable. Refer to the Engine Manual for information on these parts. If these components malfunction, contact
the factory.
3. Inspect the FADEC wiring harness for security and corrosion. Inspect all wires and plugs. Refer to the Engine manual
for further information. If a problem with this wiring harness is suspected, contact a factory service representative
before attempting to make repairs.
4. The fuse holders on the overhead switch panel and throughout the wiring harness can develop corrosion, resulting in
poor connections. Remove the fuse from the holder and make a visual inspection. If corrosion is found, clean or
replace the fuse holder and fuse.
5. Check the toggle switch by first disconnecting the power leads from the battery terminals. Then actuate the toggle
switch on and off. The switch should have a good solid snap action in both directions. If in doubt, check the switch with
a an ohm meter.
6. Check the top and bottom of the battery and ground cable eyelets for corrosion and clean as necessary. Poor contact
will cause excessive heat buildup and could result in hard starting.
