Hi Guys, anyone see something wrong with my planned rewire of my Alternator Regulator system.
Trying to avoid an issue with our old External Regulator giving out at an inopportune time.
Here's the planned diagram.
Sorry about that, my pc went to sleep and I didn't get the chance to review the image online :(
Here's the image with a white background.

[Edit - Maybe a pic of the back of your alt would help me "see" what you are referring to.]

Are you running your tach negative all the way back to the alt, or is that just schematically shown?
Which alt/internal reg do you have now, such that you have an external V sense? Maybe you've discussed that previously.
Are you calling the alt excite circuit from the key switch and from the ext reg two different things -- a little confused where/which connections at the alt you are referring to, but again dunno which alt you have.
Ken, my understanding of the internal v external regulator system is as follows.
If using the internal regulator - the 12v from the Ignition is applied to the Excite connection of the Alternator.
The Internal Regulator then sets the Field voltage as required by sensing the Alternator output voltage.
If using the external regulator - the 12v from the Ignition is applied to the External Regulator which then controls the Field voltage applied to the Field terminal on the Alternator, by sensing the Voltage at the Battery.
The Alternator is a Mark Grasser/CMI High Performance Small Case Marine 100Amp Alternator
