Yes, that will work fine for you. There are some arguments for getting as close to the battery as you can for a more accurate charging voltage measurement but a voltmeter is a high impedence device so it doesn't really matter for your purposes.

If your wiring is in good shape you should not see much of a voltage drop anywhere you measure it. If you see a significant difference (near a volt or even more?) anywhere it then I'd be worried about a bad connection or poor ground somewhere.

Here's an easy to read/use wiring drawing if you want to use it. There are a few others floating around the forums as well-

You need a Key on power sorce to to activate the relay. Once the relay is activated it will let power flow from the main source.

If you're not ready to wire up a relay yourself, or don't have a garage/shop (like me), then consider a premade one. Here is one I purchased for my heated grips and volt gauge. Very high quality and about 5 minutes to install, thanks to Posi-Lock connectors.

Available from Eastern Beaver Company (in Japan) for about $25. Can be used with heated grips or any other accessory. They make other versions as well.

Specifications:

- 20A Panasonic Relay and socket

- VOX wire covering

- 2 fuses included of your choice from 5A - 15A

- switching wire 24" (60 cm)

- grip leads 24" (60 cm) (attached my volt meter as well)

- relay located 9" (23 cm) from battery POS

- ground lead 15" (38 cm) from battery NEG

- 4 cable ties included

- Sumitube shrinktube included for strain relief on the grip heater wires

- extra sheathing for wire (Symtec yellow wire)
