Spark Bright Voltage monitor (Assimilator Upgrade)

http://www.sparkbright.co.uk/index.html

I picked up a couple of these devices. One for the Goldwing and one for the Norton. The company is great to work with and the devices so far have performed perfectly. The LED is a tri-color device that indicates Green, Amber and Red for different states of the charging circuit. The best part of this is that the LED is almost a perfect fit into the Assimilator tube assembly. The bulb and holder is removed entirely.

The warning light assembly needs to be trimmed down a bit so the LED can fit up into it. If you leave it recessed at the bottom of the assembly tube, it is difficult to see the indicator color. I trimmed it by cutting slits in the tub about 2/3 of the way up, then clipped them off.



The led fits up into the tube.



The chrome ring and the rubber shield fits back over the assembly. I wrapped the base of the LED with electrical tape to hold it in place.



Here is the assembly in the headlight. I used a piece of plastic from a CD sheet cover. It has plastic on both sides and in the middle is a paper that acts as a light diffuser. I was able to catch the center flasher light on and the headlight indicator is on the right.



In communicating with Andrew at SparkBright, he said they have a new device that changes light intensity for daytime and nighttime. It was not available when I got mine but will be available soon. It is called the Eclipse.

They come in different sizes. The 10mm is the one that I used.

Re: Spark Bright Voltage monitor (Assimilator replacement)

Thanks, good to learn of that unit and I will try one. I'm using a similar voltage monitor on my Commando from Signal Dynamics and like it a lot, though the voltage indications are for a modern vehicle and are far too pessimistic for a vintage British bike, mine only goes green when I have the headlight on (55W H4) if I'm above 3000rpm...still it does the job and would give you fair warning if your charging system failed, that happened on a friends old Bonneville recently and he was able to turn the lights off and ride home on battery power...will be buying two more voltage monitors for my other bikes and will try the SparkBright. FWIW the LED on the SD unit is visible through the stock amber lens and dims to half brightness if it is in a steady state for > 8 secs. The control box is matchbox sized and fits easily in the headlight shell but could be a pain to install on some bikes...

After deciding to rewire in negative ground, I went with the Signal Dynamics indicator because:

a) It is cheaper than the negative ground replacements for the assimilator, and

b) It provides more info that the on/off idiot light approach of the OEM device.

For my MKIII (still original alternator - Podtronics regulator), the light goes to green at around 2K RPM (with headlight on)

Just to be clear, this device is not an actual assimilator replacement. It monitors a full range of voltages similar to the SD unit. It is much more compact.

As a Sci-Fi fan, I`ve always fancied a "7 of 9" Ass-imilator upgrade for the missus, anyone got the Borg catalogue part number?

Hi , are those monitor for positive or negative ground.....?

I have one on a Honda and the Norton. They work on either.
