One STep beyond
I installed a voltmeter for checking two things:
This is an Innovate voltmeter I had. First of all, I proved it with a power supply that I have for testing gadgets.
To start installation, windshield is removed; task is easy because all screws are visible.
Next step is to remove the upper front panel, so you have to drop 4 clips (marked with red lines), other 4 (marked with green ones) and 4 screws that fix the instrument panel. In order to release the clips marked with green lines, you have to push the center of them inward to a position of "click" and then come out easily. For putting them again, you must first extract the center -remember that is embedded-, insert the clip in its housing and press the center of it until it is aligned.
Work area is like this:
This device needs 2 wires: a positive one after key and another negative one to ground that will be screwed to frame in an area that only needs to put a screw with a pair of washers to connect it.
Positive wire will be connected to the one that feeds CD radio. Here's the schematic and a link to thread where whole work is described.

New wire is driven through fairing pocket.
We've got all the necessary for electrical connections.
I insert a plate at the back of the voltmeter for giving desired orientation and add a bit of silicone for sealing it.
I pass the plate and wires through left vent window and fix the voltmeter to the frame. I've got perfect orientation, it's firmly attached and clutch fluid reservoir is at half inch distance with steering turned fully to the right. I connect the wires through disconnectable plugs.
Results are as follows:
Key to ON position. I get the battery voltage: 12.08 volts (radio is ON).
Lights on and voltage drops obviously: 11.68 volts.
Engine on and it shows 14.36 volts.
And with lights on -as it's required- I see charging system is working properly because it shows 14.30 volts.
- Key turned to the right for ON position for testing battery voltage.
- With engine running will check charging system.
