Frequently Asked Questions - AP-7V Electronics International

What is the AP-7V Annunciator Panel used for?

The AP-7V provides quick visual warnings for engine parameters such as EGT/CHT, fuel, RPM, manifold pressure, oil pressure/temperature, voltage, and starter engagement, allowing the pilot to spot problems without scanning individual gauges.

How do I install the AP-7V in my aircraft?

Installation requires an FAA Certified Aircraft Mechanic. Use the provided template to mark and drill holes (1/2" for lights, 6-32 tapped for mounting screws). Mount the front panel, connect the control box, and wire power and external warning lines per the diagram. This is typically a minor alteration under AC 43.13-2A.

What power supply does the AP-7V require?

It operates on the aircraft's 12V or 24V DC electrical system. The red wire connects to the bus via a 1-amp fuse, and the black wire to ground.

How do the warning lights work?

Five lights are controlled by external instruments (e.g., EGT/CHT, Fuel, RPM, M.P., Oil). The 'Volts' and 'Start' lights are controlled internally. All lights except 'Start' flash on power-up to verify operation. The dimmer switch can turn them off.

What does the 'Volts' warning light indicate?

The 'Volts' light comes on when the bus voltage drops below 12.5V (12V system) or 25V (24V system), indicating the battery is discharging. It should be off during normal engine operation.

How can I test the warning lights?

Short the appropriate wire on the control box to ground (e.g., brown for EGT/CHT, white for Fuel). For the 'Start' light, short the white/violet wire to the bus. All lights should illuminate during the power-up flash test.

Is the AP-7V certified (STC'd)?

No, it is not STC'd. However, it can be installed as a minor alteration per FAA guidelines (AC 43.13-2A) by an FAA certified mechanic. The installation must be logged appropriately.

What is the warranty coverage?

Electronics International offers a 1-year warranty from the user invoice date, covering defects in materials and workmanship. It does not cover misuse, incorrect wiring, or installation labor.

Can I dim or turn off the warning lights?

Yes, the front panel dimmer switch allows you to dim or completely turn off the warning lights. The 'Start' light always remains functional when the starter is engaged.

What should I do if a warning light fails to illuminate?

First, check the power supply and wiring. Use the troubleshooting test by shorting wires on the control box to isolate the issue. If the light still doesn't work, contact Electronics International for repair or replacement under warranty.

AP-7H and AP-7VAP-7H and AP-7V

The Annunciator Panel (AP-7) provides a quick and convenient way of spotting a problems or warnings without having to scan your instrument panel and interpret each gauge. If the AP-7 is mounted high on the instrument panel, you can spot the many available warnings while still keeping your focus outside the cabin.

Five of the AP-7 warning lights are controlled by External Warning Lines available on the following E.I. instruments:

AP-7Warning Light	Controlling Instrument	Warnings Provided on the AP-7
EGT/CHT US-8A, SR	R-8A,EC-1P, E-1P, C-1P,etc.(Warnings shown using US-8A)	EGT Over Temp (all Cylinders)EGT Under Temp (all Cylinders)EGT Differential TempCHT Over Temp (all Cylinders)CHT Under Temp (all Cylinders)CHT Differential TempCHT Shock-Cooling (Blinks Light)Other temp Warnings
Fuel FP-5 and/or	FL-2.	Low Fuel Warnings (Two Warnings)Time to Empty WarningHigh Fuel Pressure WarningLow Fuel Pressure Warning
RPM R-1 High RPM	Warning
M.P. M-1 High Manifold	Pressure
Oil OPT-1 High Oil	Pressure	Low Oil PressureHigh Oil Temp
Volts None Low Voltage	Discharging Cond	tion)
Start None Starter Engaged

The “Volts” and “Start” Warning Lights are controlled by the AP-7 Control Box.

Refer to the appropriate operating manual for the operation of the EGT/CHT, Fuel, RPM, M.P. and Oil Warning Lights.

The “Start” Warning Light will come on when the starter is engaged. After the engine is started this light should be out. If it does not go out, the starter or starter solenoid may be stuck on. Flying the aircraft in this condition can cause starter and/or engine failure.

The “Volts” Warning Light will be on when the master switch is on and the engine is off. This indicates the battery is in a discharging condition. When the engine is started this light will go out. If the alternator (or generator) cannot supply the aircraft’s electrical load, this light will come on. During a takeoff, climb or cruise condition the “Volt” Warning Light should be out. During operation with low engine power with a high electrical load (e.g., the engine is at idle during night operation with all the lights on), this light may come on. A point to remember: if the “Volts” Warning Light is on, your battery is discharging.

The switch on the AP-7 allows the pilot to dim or turn off the Warning Lights. All the Warning Lights (except the “Start” light) will flash on power-up. This allows the pilot to check the lights as well as the controlling instruments, circuits and interconnects for proper operation. The “Start” Warning Light can be checked when the starter is engaged.
