Sounds good, I will be checking my phone for email and try to get back to you asap.
Basically a quick test is one, battery voltage what is it? First step should be at 12.6 volts with key off. Below 12.4 would indicate a battery that is below charge. Next test is to remove the small wire that goes into the starter. Using the volt meter, check for voltage there while someone holds the key in the start position. If you have voltage there, then the problem is the starter, no voltage indicates a different problem. Those are your two starting points. Let me know what you find later today or tomorrow so we can go further.
The VR6 can be a bit difficult to get to the starter. You may end up having to remove the battery and tray to access the starter. What we have done in the shop at times, is to use a set of jumper cables once the battery is out to test the starter lead. I know it can be difficult with all the motor crammed in there.
You could also try to remove the air filter box, but I am not 100% sure that you can access the starter lead, the air box is simple to remove. Two 10mm bolts on each side, disconnect the conector and air tube
