Hello fellas,
I´ll have to replace my regulator mechanical box for a new DC 6v.
I´m looking for a model to charge the battery at low revs
the first option is: Dynamo regulators DVR2
looks really nice, and seems to do what I need, but shipping it´s a bit expensive for me £49 + £54 to ship to Brazil
The other one is: Wassel MCR2 for £34,95 + £9 to Brazil!
but I´m not sure if Wassel will do what I need.
Any one here use any WASSEL model?
it´s a good box for charge at low revs?
or should I buy the DVR2 from dynamo?
Thank you,
Giorgio

Guys!
I took a look at "Wassell Regulator" topic right now and help me a lot!
I belive that DVR2 is the best option, right?
Cheers!

G'day Giorgio,
I think the DVR2 is the best option. It will hide inside the old reg box. While your at it why not put in a dynamo belt drive kit to help with low revs.
Postage to over there is even worse than here *rant*.
Cheers

... I guess you need good charging to get good lights, so think about getting some halogen bulbs as well.
-
Giorgio,
Have another look at the DVR2 shipping cost.
They cost 52.00 including postage to Australia so should be similar to Brazil.
-
I landed a podronics from USA a couple of years ago for buggerall postage. Maybe it's changed now.
-
Yes, Giorgio, you've misunderstood the cost. It's GBP 54 for the DVR2 including postage to Brazil.
This graph might help you choose between DVR2 and Wassell

The Belt drive it´s really cool stuff!
My mechanic tell me to buy one just in case, but we are trying to make the bike as original as possible.
BUT! I want use the bike, so some parts must be more trustworthy and efficient.
I´ll start change the original 6v regulator for a DVR2 and see wath happens
If the regulator work fine at low revs, great! if not, I´ll have to buy the belt.. :(
about the shipping here, it´s a bit expensive, the worse thing it´s the customs assalt!
we have to pay the parts + shipping + 80% tax
for several times already thought about moving to a bether country... :(
thanks for help!

*smile*
for sure!!!
I´m using all original 6v bulbs. The bike it´s not ready yet, we are almost done with. Must be fun ride at night!
I was looking some LED bulbs, it should have a nice light with consumption

80% Tax *eek* *eek*
What about 2nd hand parts for vintage/obsolete bikes? Mike might put a scratch in one and call it 2nd hand. *shh*
Cheers

Now one little thiing concerned me in your original post.
The regulator has little effect upon charging your bike at low revs.
If you generator does not produce 6V till 3000 rpm then no regulator on earth will make it produce 6V at 1000 rpm.
All a good regulator will do is efficiently turn on or off your generator.
If you want more zappies at lower revs you either have to rewire the generator or regear it to turn faster.

I already tried that!
They tax everything, used or new
I always ask sellers to mark lower values, works better with 2nd hand or used parts, it´s possible to get more lower values.
I know it´s not a cool stuff but works the most of time and help me to save some money, not giving money to the corrupt government.

Terrific!!!!

the graph really help, will buy one DVR2!

Right!
the best thing to do is install a dynamo belt drive as muskrat suggested.
Thank you very much for the all the tips guys!

If my generator didn't produce 6V until 3000 RPM I would scrap it!

Just a number I pulled from the blue Trev for the point of making a point but, on that point, point taken.
have I been listening to too many election speeches ?

Hi Guys, I seem to have the same problem, Discharge shows on the ammeter with no engine running and the same with engine running no matter how I rev it. I've checked and rechecked my wiring and can't fault it so its got to be the reg/rec. (Original equipment with the alloy cover and rubber bush studs RB108?) I have had the dynamo checked and its ok, even had a new field coil fitted even though the old one was showing correct ohms. I had skimmed and undercut the commutator and fitted new sealed bearings and new brushes (original Lucas nos). The test gave the dynamo a 100% rating. Although I checked the output from the reg' and I was getting 7.6 volts after adjusting. Gerry

Giogio,
You probably have noticed this, but the DVR2 needs to be orded as positive or negative earth, it is not selectable on the unit. I mention this because Ken's graph only mentions negative earth. i'm sure the results are the same for positive earth.

Gerry,
If you are getting 7.6V and your ammeter is showing a discharge, either the ammeter is faulty or connected wrong.
Usually if the ammeter is showing discharge with the engine stopped it is because the cut-out points haven't opened.
When this happens there is a heavy (full scale) discharge shown because the battery is trying to motor the generator.
You could try disconnecting the "D" wire and see what happens to the ammeter but I feel that if the regulator is at fault your battery would quickly discharge and your dynamo wouldn't be very happy.
