Fred. When connected to a power supply, it will show the voltage of the power bus it is connected to.
In our Ercoupes it will show 12 Volts or less with the engine running below 1300 rpm, provided yours is having a generator. If the engine is faster than 1500 rpm, the voltage should rise and show in excess of 12 volts, depending on the outside temperature. The regulator is adjusting the voltage according to the condition the battery is in, including temperature. It needs a higher voltage to charge a cold battery. That's why you have the regulator mounted close to the battery and will see close to 14 volts in cold weather conditions.

I will se what it shows when hooked to the airplane cig lighter. (when I get it back form my annual in March). You say it should be in excess of 12 volts?

In the Garmin manual for the 696 on page 136 Appendix A: DATA FIELD OPTIONS, we find the "• External Voltage—the voltage on the external power input (cigarette lighter receptacle)." listed . >From the manual on page 30: Changing the information shown in the data bar fields:1) From the Map Page, Terrain Page, or the Info Page press the MENU Key.2) Turn or move the FMS Joystick to highlight ‘Change Data Fields’ and pressthe ENT Key.3) Move the FMS Joystick to highlight the desired data field.4) Turn the FMS Joystick to access the list of options, then turn or move theFMS Joystick to highlight the desired option and press the ENT Key. There is also an image showing how to select the voltage. Good luck.

I should never have sold my 196. Unfortunately maybe I don't know how to do it. I can't seem to get volts info on my 696. You did a great job of showing how to do it to the group. Keep up the great advise to us. Prof. Ed Hotmail: Trusted email with Microsoft’s powerful SPAM protection.
