Goldnboy 927 #1 Posted May 13 Why in this basic wiring diagram is the lights connected to the A vs the R terminal as shown in the Full diagram? I am thinking the full diagram is wrong... Share this post Link to post Share on other sites
pfrederi 17,743 #2 Posted May 13 I do not think it makes much difference. The A and R terminal are both only live when switch is in run position. 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,072 #3 Posted May 13 The regulator requires power on the DC+ to turn it on so to speak. This is done by the A terminal on the ignition switch in the RUN position. When switched to OFF the A terminal is no longer powered and grounded. Suspect this is to absorb any stray voltage spikes. One of the regulator terminals is connected to the DC+ terminal inside the regulator so AC current goes to the battery with the DC current. This may have something to do with the way it is wired. Recall SOI explaining it but have forgotten what he said and not smart enough to figure it out. Share this post Link to post Share on other sites
