Charging system question

Does the use of a rectifier/diode eliminator such as used on a Sparx alternator effect operation of the charge system light? If I'm not mistaken the power to turn the light off comes from one leg of the rectifier? With the Sparx unit wired to dump alternator output directly into the battery I see no way of isolating the assimilator from the battery. I know my assimilator is bad but don't want to replace it if it's not going to work anyway.
Thanks

I think the unit runs on the AC side. You may have to splice it in series to one of the wire before the pod unit
WARNING, i am assuming.

Just buy a new modern solid state type of warning light assimilator, they are affordable and does away with the pathetic little internal springy that heats up and expands to open contacts. The warning light goes out when you are producing power eg. running. Affect ,assimilate, assume ?

It does hook up to the AC side. It does not go in series so no splicing required. It just has to hook to one of the AC leads from the alternator. (I'm ASSuming you have the earlier type assimilator.)

Yes. Or just eliminate it and use the light with an inline oil pressure switch.
Just a thought.

it does work ( some times ) off the AC side BUT the higher out put of the 3 phase stator will cook it.

I have been looking at one of these. Should be able to route the led into the original assimilator lens in the headlight bucket.

It would be a good way to have a quick indication of the alternator, regulator(zener) or rectifier failing.

The link wouldn't open for me but I think you must be referring to their Heads Up voltage monitor. There was an earlier thread on these here. I am on my 3rd one. They keep on replacing them under warranty because after 3-9 months they have died with the red light on all the time. This time I added a 20V zener and a capacitor across the input for protection against spikes. I also added small snap on ferrite cores to all the wires. You have to put it in the yellow turnsignal lens otherwise you won't see the right colors. I'm running that and a SS3AW from Cool Cat instead of the stock assimilator. I have the Lucas three phase alternator and the original assimilator lasted for many years like that until I forgot to connect the spring and it seems to have vibrated itself to death from rubbing against the frame. (I took it apart.)

I did exactly that and it works well, visibility is best with the LED behind the amber lens. Made a post on it awhile back at http://www.accessnorton.com/voltage-monitor-demo-video-t7576.html
