Does anyone know if there is any wiring behind the c b knock-out plate looking to mount a volt meter need hot wire.

If my bike is any indication, you want to run a fresh wire from the battery, through an ingition-switched relay, to get a true indication of voltage. Anything on the ignition/accessory circuit reads at least 1.5-2.5 volts below actual battery/alternator voltage, so is effectively useless. I mounted an extremely accurate voltmeter, just above the CB, running off one of the accessory circuits, and it reads 12.5-13.1 volts while the engine is running...the actual voltage is 14.1 volts.

I'm going to be re-wiring it as I suggested above. A gauge that is wildly inaccurate is worse than no gauge at all, IMHO.

Thanks for the info
but before i start takeing it a part was wondering if it was wired for a cb even though i do not have one on this 1997 1500 A

I'd say it most likely has the CB harness connectors since the Aspencade stereo system was designed to work with the CB.

The wiring I propose is actually pretty easy. The reason for using a relay is that you can use a power wire directly from the battery (so you get a true voltage reading), yet when the ignition is turned off, the volt meter is turned off so as not to run your battery down. A relay is nothing more than a switch to accomplish this - it is triggered by some other circuit that turns on & off with the ignition (such as the power wire for the CB). Relays can typically be purchased for around $5 or less, and can be found at any auto parts place.

The hardest part is physically fishing a wire from the battery, up under the false fuel tank cover, to the back of the CB panel. It's not hard, just annoying & fiddly, but it can be done in a few minutes. The relay can live in the space behind the CB panel (and behind the volt meter).

You don't have to do it that way, of course, but I believe it's the right way, and you will be able to accurately monitor your voltage/battery condition/alternator health.

If you want a hand with a simple circuit diagram to do this, we can gin one up for you, no problem.

I totally agree with this.
a voltmeter that gets it's sense source anywhere except from the battery terminals direct, is useless, might as well have a bulb that if it is glowing bright, "All must be okay".

I wired my Analog voltmeter direct to the battery terminals w/o a relay.... this is problematic because if I forget to plug in the Battery Tender, in about 6 or 7 weeks, the bike won't start up. A voltmeter does not pull very much current, but it does draw a few milliAmps, and eventually, that will drain any battery, even the AGM on my bike.

Don't forget to put a fuse inline on the battery (+) wire just off the battery so as to protect the electrical system in case of short circuit.

Those who say it cannot be done should try not to interrupt those who are doing it.

A pickup point for switched power is at the top of the fuse bank on the left side of the bike. Prior owner had connected the VM there, but without any fuse protection, which was one of the first things I had to correct. Didn't think about the relay aspect of it, gonna leave it as is.

This is the same thing I need to do also.
But mine is for a knock out power panel with 4 empty rocker switches and a double 2.1 amp USB port.

Then I also need to wire up a voltmeter lol.

Great info above. Awesome community here!

Good luck you, and I, will get it done.
