Anyone know if green/red regulator wire is a "hot when running" wire?

April 22, 2007, 04:57:05 PM

Just been looking through my wiring trying to solve my stalling in the rain problem. Right now my HEI ignition is switched on by a relay that I decided to trigger with my factory coil wire. But I'm getting suspicious of that connection so I'd like to trigger it some other way. And that green/red wire that connects the regulator to the instrument cluster is very handy to the relay. Anyone know? I'd rather not splice into it until I'm sure.

It should be ignition switched, but it's switched through the AMP light in the dash. Connecting anything to it might cause your AMP light to come on and/or might result in not enough juice getting to the relay, or coil, or whatever you connect.

It should be ignition switched, .

when i read his post and looked up the wire,, i was kinda wondering how to "word" it, but i think you described it perfectly.

Red/Green is generally the switched Hot feed... It may feed TO the amp light, but it shouldn't make any difference as it(light) is operated(grounded) from the contacts in the regulator...

I just installed a wiring harness in a '65 Shelby that being restored, even way back then red/green is the switched coil feed(through the resistance wire which is pink)...

The Red/Green (as in red with green stripe) wire may be the switched "hot" wire at the coil, but as I understand his question he's asking about the green/red wire (as in green with red stripe) at the regulator. If the green/red wire is the one he's talking about, this wire is fed through the ignition switch, then the AMP bulb, then to the regulator. This is the wire that grounds the AMP bulb if there is a problem with the charging system, but it's also the "I" wire that turns the regulator on. This is why I said that connecting a relay (or anything else) to it might cause the AMP light to come on:

He is talking about the green with red tracer wire at the regulator.
Which is on the ground side of the AMP warning light.

You are right, a red with green tracer wire would be a hot with ignition on wire. But there are none of those on the regulator.

Green/Red... Red/Green... doesn't make any difference... Just like traffic lights... :hick:
