TRON Posted March 10, 2014 Report Share Posted March 10, 2014 Decided to test the new alternators I got a few weeks ago. Dual setup so one unit has the stock plug (2 PIN) and the secondary has the 4 PIN. The 4 PIN plug Mechman provided only has a turn-on wire (yellow). So I was going to wire up a relay for it but... Shouldn't there be a field wire to attach to the output stud or something? How is the second alternator regulated then?

MECHMAN Posted March 10, 2014 Report Share Posted March 10, 2014 The alternator is internally regulated. All it needs is 12v Turn on source to the yellow wire Quote 1-888-MECHMAN www.Mechman.com [email protected] Link to comment Share on other sites More sharing options...
TRON Posted March 11, 2014 Author Report Share Posted March 11, 2014 The alternator is internally regulated. All it needs is 12v Turn on source to the yellow wire Okay. Would it be okay to use a 12v relay as opposed to just tapping into a turn on source?

SnowDrifter Posted March 11, 2014 Report Share Posted March 11, 2014 That wire -- is it simply a low draw turn on wire or is it the regulator sense/power wire? If it "powers" the regulator, you'll want to use a relay anyway. And thick wire too IMO Quote ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
