Not today, but last week I put a volt meter on my RGS. The bike was off the road from late last year to early April. I had it apart to have the head-stock reinforced.
After I put it back together, the battery wasn?t charging. While the bike was running, I put a multi-meter on the battery and it would not move off 12.2V. The alternator was putting out current, and it was alright before I pulled the bike apart, so I undid the nut for the regulator earth and made sure I had a good earth to the frame. I thought it should be right now.
Started it up, and gave it a rev and it still read 12.2V, wouldn?t budge. The bike nearly conked out (it was cold) so I gave the throttle a blip, then gave it a good old revving, it back fired, and it started charging. The multi-meter shot up to around 14V and revving the motor caused the volts to fluctuate up and down, as you would expect.
I thought that was totally weird, and I was about to go for a ride for the day with mates and thought it would be good to know if my battery was charging or not.
The next week, I bought one of these off eBay.
I removed the display from the circuit board and soldered wires to the legs of the display.
I mangled one of the spare rectangle sections in the instrument panel to fit the display.
Re-soldered the circuit board to the display.
I used a bit of plastic as a mounting bracket. I used masking tape to hold the circuit board to the
bracket and took power from the circuit board.
I ended up wrapping the circuit board in masking tape and foil, and running a power lead to source power from the back of the ignition key (at the wiring loom below the steering stem) and earth at the frame. Before doing this the volt meter display blanked out when the motor was revved.
I haven?t ridden it with the volt meter fitted yet because I?d had a few beers by the time I?d finished the job last Sunday afternoon. I?ll take it for a ride tomorrow morning and see what it does.
