I’ve tested the JD rectifier/regulator and found them to be good substitutes for whatever OEM R/R are supplied (single phase PMs only, of course).

Hi Sebastien,

I’ve never worked on the Jabiru alternator but have spent countless hours on a similar “integrated” alternator on the Revmaster. Both are 12 pole permanent magnet (PM) anlterna ...

John,

You asked this question in the original post:

Also, would testing continuity from the Aera d-sup to the monitor or ELT connection be worthwhile? The other 232 output on the Aera is worki ...

Hi John,

For wiring to the serial to USB breakout, you need the gnd wire (pin 1 from the Aero) in addition to the TX (pin 7 from the Aero). So, 2 wires need to be connected from the Aero to the US ...

Hi John,

1. Would I connect pin 7 (RS232) to the RS232 TX terminal and pin 1 (gnd) to the RS232 GND terminal?

Pin 7 (TX) will be connected to the RX terminal on the breakout. The connections ...

Hi John,

The breakout converter would be best used by segregating the pin of interest (pin 7) and excluding any of the other pins from being connected to the PC (via the converter). You will also n ...

John,

After a quick check of the connections you have on the aero660 housing, I think you might be better off with a serial to USB breakout connector.

John,
if you have a PC and a “usb to serial” adapter, along with a freeware utility like “Termite,” you can monitor the serial port output. A low cost SERIAL TO USB adapter can be purchased ...

Just a few thoughts on the concept.

A fail safe software solution is a challenge but “doable.”
A fail safe hardware implementation might be a larger challenge but still achievable.

What w ...

Very nice.
I second Joe’s recognition of your contribution to the group, Eric.

Hi Finn

I've been using the "pico scope" 2000 series out of the UK.

This requires a PC (laptop) but I find the ex ...

…….Is anyone else confused by Figures 2, 3 and 5 in the EarthX article that Joe linked above?……..

Yes, at a minimum it’s unclear what they are trying to convey and certainly misleading. ...

If the separate contactor is necessary, then please explain:
1. Why?
2. Should it supply all power to the starter -- both motor current and control signal -- or, just the control signal?

I th ...

Nice design Eric.

In particular, I appreciate your use and reasoning behind switching the AC side of the charge circuit. Reliable switching of higher current DC generally requires relays that are ...

BTW . . . I've searched my library for a copy
of the R-2300 installation manual and came up
empty. Can anyone point me to a download link
or email me a copy?

Attached is the "Electrical&qu ...

Increasing air flow is job 1, wrt cooling this stator. Impregnating the wiring is an improvement that I advocate but do not have data on it. My direct conversation with the stator wire manufac ...

I’ve been trading emails with another builder and they asked my thoughts on the location of the ship’s voltage regulator. “What are the pros and cons to mounting the regulator on the occupant s ...

Checking the DC current after the voltage regulator would not be as indicative since there would be some loss in the regulator and if the regulator is the shunt type DC current would not represent wh ...

Good question Paul and I believe the short answer is “yes, temperature will affect battery performance.” It’s a common expectation that temperature will impact any chemical reaction rate and ba ...
