Hi.
1971 SS bike.
The warning light to day doesnt switch off.
The wires from stator to rectifier and to warning light are well fixed.
I cannot believe there is broken again, it was new.
To morrow i will check if the stator charges the same.
Ciao

Please,
there is an easy and quick wau to check if rhe stator charges?
Thanks
Piero
 
Hi Piero,
The easy way to see if the stator is making "power" is to get a "multimeter" and set it to volts (set on direct current) across the battery terminals, start the engine and the volts should initially be approximately 12.7 volts whilst the engine is on tickover, and as you slowly rev the engine up to 3,000 to 4,000 revs, the voltage should increase to about 13.5 to 13.8 volts. When the engine is returned to tickover, the voltage will again drop to about 12.7 volts.

If this happens, then your battery is being charged and this shows that the stator is working correctly.

Hi Piero, this is what I did. use-20b-relay-instead-the-assimilator-t19684.html?hilit=warning%20light

I cant explain why it works but it does, cost me $5.00 NZ instead of $65.00 for the geniune type assimilator. Why waste money one the real thing when you can spend it on your 850.

Hi.
I mean.
Who supply it?.

Its a standard 5 pin automotive relay. Has the power off and power on positions. Just wire it up so the power on goes to the warning light. The warning light itself serves no function in the charging circuit, except light up when its not charging by way of the assimilator, the relay mentioned or any of the other methods mentionned above,,.

And automotive charging systems can charge up to 14.5 volts and still be working fine.

As above - should be DC volts, if not it will either blow the 10 Fuse that most are fitted with or melt the MM.

Shouldn't that be DC Volts!!

If you're referring to my reply then I believe it should be AC. The assimilator provides a ground (earth) to the warning light in the absence of AC voltage from the stator. That's not a lot of useful information hence my preference for the voltage monitor which looks at the DC voltage, the one the bike runs on, charges the battery, etc, and gives useful information about that.

As Reggie said, "set to Volts DC". :?
 
Hi.
The stator charges fine.
Another warning light simulator broken, and it was new, less than 3 days his working life!
Now the question is: are this warning light fragile or ?????

Got it now, reminds of the days of the AVO moving coil meters. Just get so used to selecting it in one go with the DVM these days. As for the assimilator there are better alternatives BSM's that actually indicate what is happen with your Volts direct current and thus the system is actually charging and not just telling you the alternator is rotating.

AVO; DVM; BSM: sorry, what do they mean?
