P1000 True am isolator and relay wiring

[Laughlin74]

I’m almost finished with my dual battery setup. And I’ve searched several places. I’m not clear on the wiring of the relay that comes with the true am setup. I thought I had it figured out but my dual voltmeter setup stayed lit the whole time. Even when machine was off. It has 1 black 1 red and 2 green/white stripe wires. Any help appreciated.

I did this exact setup. And it stays lit all the time. I guess I don’t understand the spare activated ignition ground?

 

[Hondasxs]

Its a spare.
Did you use it for anything?

I grounded it in the fuse box

Oh. Why did you do that?
Disconnect it.

It's a spare ignition-activated ground. It only is grounded when the key is on. It has a purpose, but most don't use it.

Ok thanks. I will definitely do that tomorrow. Idk why except I translated activated ground as a ground. I thought 2 green wires both needed grounds. Oops. I’m no electric wiz. But I’ve learned a lot on here.

None of us were born knowing this crap. Well except @Hondasxs hisself. 😎

Unhook that spare green from ground and you should be good. If not, let the guys know and someone will figure it out.

Yep, that's your issue.
Tape off the second green wire for other uses.
Not much needs a ground trigger tho.

LOL... Most of what I have learned has been from similar F-UPs.

 

[Laughlin74]

Thanks. I did unhook the extra geez wire and everything normal now.

 

[Hondasxs]

Woohoo...

Next...
The blue light may seem to stay on. You can turn on the headlights for a few seconds and it should turn off. This is normal.

What HondaSXS is saying is there's a small blue LED inside the isolator that stays on after you turn off the power.
It was installed by a sadist who knew he'd mess with people's heads world-wide asking how to turn the damn light off, how to stop it from draining the battery, etc., etc.
It's not a problem. Don't lose any sleep over it. It is normal.

If you would like to check your two battery's voltages without turning on the ignition, there's an easy mod you can do. Besides being convenient, it offers the advantage of "looking" at both batteries under the same no-load condition. With key on, it's not a fair comparison as the main battery is instantly loaded by all the ignition-on circuitry so that battery will read lower than the aux battery.

To accomplish this you only need a normally open (abbreviated NO) momentary push button switch like THIS. Wire one lead from the switch to the negative terminal of the dual volt meter (where the green or green/white wire is now) and connect the other terminal of the switch to a ground. This switch is shown below the dual voltmeter in this picture:
