I would like to answer Bob N.’s points and questions from July 30, 2010, in parts. This is about the John Deere Rectifier/Regulator AM101406

I would like to use the JD101406 Rectifier/R ...

I have laid out a preliminary electrical system schematic for an all metal aircraft (Sonex) powered by a Jabiru 3300 engine. I would appreciate Bob’s and other lister’s comments. I have ...

The design goal for this light:

This light is to be an indicator that the E-bus alternate feed switch is in the on position even though in most cases there would be other indications.

My thought ...

So if the power source for the LED came directly from a tap on the e-bus itself as you suggested as an alternate, in that case a double pole switch would be required?

Therefore I assume it is OK to tie the ground sides from the LED and the relay coil together through a single pole switch.

I would like to include an Off/On indicator light (LED) for the E-Bus alternate feed when using a relay as in Z-32 for a heavy duty E-Bus Alternate Feed. I understand that the LED will have to includ ...

I think the following questions relate to the current string with the subject: “ANL current limiter location on rear battery Installations.”

I think that item number 1. below relat ...

Given – You have installed a device for active notification of low voltage that moniters Main Bus voltage and lights an indicator lamp/Led if voltage drops below a programmed level.<?xml:namespac ...

Is there a 12V. Relay device (SPST or SPDT) that can be toggled OFF/ON from a remote momentary SPST mini switch? It should remain in the off or on position until toggled again. I am looking for some ...

I wanted to purchase a JD AM101406 for use as a Voltage Regulator controller for a 20A. PM alternator installation. It has been touted as a “Robust” option for replacement of other regula ...

I find some inconsistencies regarding E-Bus feeds and I can’t understand the physics that might drive the decision for these differences. Or a ...

Do you have a ballpark estimate of when the AEC9024 modules might be available for sale? Do you have a ballpark estimate of what the price might be?

When the AEC9024-20 is used as ...

In the AEC writings, Matronics postings and Z figures I see references to Permanent Magnet Alternators and Dynamos. Are they one in the same; is the physics basically the same? For instance in a Rot ...

Many current OBAM aircraft have electronic EFIS and/or EIS systems installed in their panels. Most of these systems have the capability to monitor various engine and electrical parameters. Limits ca ...

When you get to the point of building and selling your AEC 9024 module, will you also be building and selling your AEC 9011 module?
