Hah! With all the help you’ve offered in the past, you have no need to thank little old me! ��
Nevertheless, you’re welcome!

HI Gordon,
Sorry to bother you.

I have a Heart Interface Link 1000 (installed 2001) that is reading .3v low.
I have calibrated my meters against a digital variable power supply and they all read the same within .02v
Also the accept voltage of 14.4 while charging my new batteries reads 14.05/14.01 on the link and 14.4 on all 3 of my meters.

I have looked at the thread from 2007 re calibration on the Link 1000 and have just joined the cruiser forum,
In that thread you detail how to get the link1000 to recalibrate the voltage displayed.
Am I correct in thinking that I can leave the power supply voltage at a nominal 12v ie still connected to the battery, while connecting the Bat1 and Bat2 inputs to 40v in order to get the voltage calibration to run.

Should I append this to the thread - ?

Best Wishes

I left out a "not". I could have also said net "source".

You were recommended for crewing. Do you have any day or small trips coming up for a newbie, beginner woman crewer?

Gord: Do you remember a long time poster, a Canadian, don't remember his name, who was building a trawler in his back yard. I can't find his thread. Curious as to his status

Good day, I am General Austin S. Miller, I am new here and I seek friendship and possible partnership.

Please let me know what your email is also. The address I wrote down doesnt work.

Gord,

Thanks so much.
Heres the skinny:
Lofrans Tigris 1500W windlass.
12 VDC
Assuming ~60 feet total wire run for my 37’ Crealock to windlass and back to battery
A=P/V = 1500W/12.5V = 120 amps
10% permitted drop
VD=10% x 12.5 = 1.25V
CM=(10.75 x 120A x 60 ft)/1.25V
= 77,400/1.25 = 61,920 CM
Per table CM for 2 AWG is 66,369 which is larger than 61,920 (by almost 10%!)
So I hope for 2 AWG

I show below some picture of my system which will be:
1. Windlass
2. Solenoid control box
3. Wire
4. Circuit breaker
5. Battery
6. Remote control

Dear Gord, hello from geoleo. Do you consider yourself to be a "rustic character"? Thanks

Gord thank you for the article. It is missing page 110. Any chance you could send it?
