STC Service Bulletin 2134 Page 1-7 April 23, 2021 Revision A **MANDATORY**
STC SERVICE BULLETIN NO.: 2134 Rev A TO: Garmin Aviation Service Centers DATE: April 23, 2021 SUBJECT: Modification of GEA 24 Resistive Fuel Probe Interface
CERTIFICATION AUTHORIZATION: FAA STC SA01899WI MDL Revision 10 (see Approval section for details) ______________________________________________
PRODUCTS AFFECTED All aircraft modified with G3X Touch AML STC SA01899WI, MDL Revision 9 or earlier, with an interface to resistive fuel quantity probes are affected.
Aircraft that are not affected:
• Aircraft modified in accordance with G3X Touch STC SA01899WI, MDL Revision 10 or later
• Aircraft without fuel quantity gauges displayed on the G3X Touch
• Aircraft without a resistive probe interface (e.g. all CiES probes or Signal Conditioners) If the MDL revision used for the installation and the type of fuel quantity probes are unknown, do the following:
1. Inspect the aircraft maintenance records for a Garmin Service Bulletin 2134 compliance statement.
a) If the maintenance record includes a compliance statement, no further action is required.
b) If the maintenance record is not available or does not have a compliance statement, proceed to step 2.
STC Service Bulletin 2134 Page 2-7 April 23, 2021 Revision A
2. Inspect the wire harness for the GEA 24 P244 connector to determine if resistors are installed (see Figure 1).
Figure 1 GEA 24 Connector P244
a) If resistors are not installed, the aircraft is not affected by this Service Bulletin. No further action is necessary.
b) If resistors are installed, or if the harness cannot be adequately inspected for resistors, the aircraft may be affected by this Service Bulletin. Proceed to Step 3.
3. Inspect the fuel quantity sensor configuration.
a) Press and hold the MENU key on the GDU while applying power to enter Configuration Mode.
b) Select ‘Engine & Airframe’.
c) Scroll down to Fuel 1 through 4.
d) If the fuel quantity sensors are configured as "Voltage" or "Frequency", the aircraft is not affected by this Service Bulletin. No further action is necessary.
e) If the fuel quantity sensors are configured as “Resistive” sensor (see Figure 2), the aircraft is affected by this Service Bulletin. See the MODIFICATION INSTRUCTIONS.

STC Service Bulletin 2134 Page 3-7 April 23, 2021 Revision A
PURPOSE NOTE This Service Bulletin supersedes Garmin Service Bulletin 20138.
The G3X Touch fuel quantity gauges may provide erroneous indications when (1) interfaced to resistive fuel probes and (2) the GEA 24 is subject to significantly hotter or colder temperatures than the temperature at which the fuel gauges were calibrated during installation.
This fixes the issue described in Garmin Service Alert 20137.
DESCRIPTION This Service Bulletin provides instructions to modify the resistive fuel probe interface.
If the aircraft is affected, follow the MODIFICATION INSTRUCTIONS to replace the resistors in the harness, change the sensor configuration, and recalibrate the fuel quantity gauge.
STC Service Bulletin 2134 Page 4-7 April 23, 2021 Revision A
COMPLIANCE Mandatory: This STC Service Bulletin must be incorporated within the next 100 hours time-in-service (TIS) after April 23, 2021 or within 12 calendar months after April 23, 2021, whichever occurs first.
APPROVAL This Service Bulletin is FAA-approved in accordance with STC SA01899WI. Refer to the Master Drawing List, 005-01320-00 Rev. 10 or later FAA approved revision.
DOCUMENTATION CONSIDERATIONS Existing Aircraft Flight Manual Supplements and Pilot Guides are retained for this installation. No new documents are provided with this Service Bulletin.
All documents described in this bulletin are available at no cost in the Dealer Resource Center on the Garmin website https://dealers.garmin.com.
REFERENCES All documents described in this bulletin are available at no cost in the Dealer Resource Center on the Garmin website https://dealers.garmin.com.
MANPOWER Eight (8) hours labor per affected aircraft to update the interface and recalibrate resistive fuel probes.

MODIFICATION INSTRUCTIONS Perform the following for any aircraft affected by this Service Bulletin:
1. Remove all electric power.
2. Disconnect the P244 connector from the GEA 24.
3. Remove the connector backshell and cable clamp.
4. Identify the resistive fuel quantity interfaces which have a 1K ohm resistor installed in the harness. To assist with reassembly, note the probe wire number and tank.
NOTE There are four possible interfaces (FUEL QTY 1, 2, 3, and 4 on P244 pins 6, 9, 12, and 15 respectively).
5. Remove the applicable connector pins.
6. Remove the resistor(s) from the harness.
7. Install a pair of 2.2K ohm resistors into the harness for each fuel quantity interface in accordance with the G3X AML STC Installation Manual (190-02472-01 Rev 9 or later) section B.30.
NOTE Specifications and acceptable part numbers for the 2.2K ohm resistors are identified in section 3.1.2 of the IM.
8. Assemble the connector backshell and cable clamp.
9. Install cable ties for strain relief in accordance with IM section B.34.
10. Install the P244 connector on the GEA 24.
11. Connect appropriate sustainable source of power and apply power.
12. Press and hold the MENU key on the GDU while applying power to enter Configuration Mode.
13. Select ‘Engine & Airframe’.
14. Scroll down the list of sensors on the GEA 24 Inputs tab and identify the fuel quantity interfaces labeled Fuel 1 through 4.
15. Change the configuration from ‘Resistive’ to ‘Voltage’ for each resistive fuel quantity interface in accordance with IM section 5.33.1.9 and Table C-6.
16. Perform the fuel quantity calibration procedure for each interface in accordance with IM section
5.33.1.9.1.
17. Complete the post installation check out procedure in accordance with IM section 6.15.8.
18. Remove the placard installed on the instrument panel by SB 20138, if applicable.
19. Make the following entry in the aircraft maintenance record (airframe logbook):
The G3X Touch EFIS installation in this aircraft complies with Garmin Service Bulletin SB 2134 Rev A.
STC Service Bulletin 2134 Page 7-7 April 23, 2021 Revision A
MATERIAL INFORMATION Garmin will provide the new resistors upon request, contact Aviation Product Support and order p/n 011-05829-00 (Sub-Assy, Resistor Kit, 2.2K Ohm).
NOTE This kit contains quantity (4) resistors p/n RN60D2201FB14 which is enough to modify two fuel quantity interfaces. If the aircraft has more than two resistive fuel quantity interfaces (i.e main tanks plus aux tanks), order a second kit.
