I am thinking of fitting a Voltage Guage to my 906. Has anyone done this before?

If so any information & pictres would be appreciated.

I used an universal voltage gauge once as I had problems with the regulator.
It was one of those cheap small, but long digital gauges which also show internal/external temperature. You can find them in any car shop usually. It was only so high that it could be fitted above the instrument panel (in the gap between the instrument panel and the front fairing. As it was illuminated and digital and only had a + and - wire to connect I had to include a small switch to turn it off. There`re for sure better solution, but this did what it should.

it was something like this

I bought a rather large voltage gauge to run on a total-loss race bike, but it turned out the LED display drew too much power, kinda defeating the purpose. So I shelved it.

I have just installed a Battery Monitor on one of my bikes to test. It is sold by Electrical Connection, part # 04101, available at http://www.electricalconnection.com. It is a small LED that is red below 11.5v, yellow from 11.5 to 11.9v, and green 12.0v and over. Costs $25.

Here's a pic of it installed:

It's the little one in the middle. The ones above are neutral light and low fuel light.

Here's the Monitor on the bench:


In my opinion, the light is not bright enough. The 2 LED's above it are easily visible in daylight. The Monitor's light is not as bright. However, it can be seen, and the information it provides is better than the simple "idiot" alternator light.

What I have learned from blowing up 5 rectifiers over the past 15 years is that frequently there is a warning. Two of my rectifiers burned out one half of the unit several months prior to completely failing. They wouldn't charge the battery at idle, but as the rev's rose, the one side was enough to begin charging. Hopefully this Monitor will catch this before I'm stranded on the side of the road, calling my wife to bring me another battery so I can ride it home!

For the Paso I'm trying to come up with something that will also show overcharging. I burned up several batteries on my first Paso because of the overcharging issue. Haven't found a meter that does that yet...

I have got the answer to your problem. I have just purchased a Heads-Up LED Voltage Monitor. Tese are made by the Signal Dynamics Corporation (USA). (SignalDynamics.com). These cost about $35 but the LED flashes green at over 15 vdc, steady green at 12-15 vdc, stedy amber at 11-12 vdc, steady red at 10-11 vdc and flashes red at below 10 vdc. It also self tests when initially started (red,amber,green) and auto-dims after 7 seconds.

I installed mine today and found out that my Paso 750 is overcharging above 2000 rpm.

Hope this info helps.

How many Volts You mean by "overcharging" ??? Normally Ducks dont charge battery in idle 1200RPM, but should start over that. Good voltage for starting battery is 13.6- 14.0 V and that should be quite stable till redline.

By 3000rpm the voltage is about 18v.

SURELY TOO MUCH!!!! Change regulator and check all charching wires!

Btw, with SUCH voltage, Your battery is VERY SOON drained and its gone also!

Al, I think that antti is right! remember yuo're betting your ECU (electronic ignition box)! :thumbdown: They don't like overcharging! :ugh:

Nicola dear, 750 DONT have ECU(if its EU modell), only Kokusan modules and those are not so sensitive to over voltage... But If its "bad" USA Marelli modell, then that can happen and then very hard to find new Marelli unit. Those Marelli systems seems to be quite bad, cause very many have gone to "heaven of ECU:s" :laugh:
