12 volt

[LJ.]

Thanks Trev... That's a helpful reply!

Probably my pictures of the regulators are a bit decieving as the left one looks quite crummy compared to the cleaner right one, making the right one look newer and later. But... the right one does look much more updated and streamlined. It just goes to show that appearances can be quite deceptive.

Thanks again!

Hi all,

Have read the 12 V's 6 volt posts and have a couple of questions.

I am presently restoring a 53 flash and have opted for the DVR to replace the MCR with the SRM toothed belt drive mod.

With some other other Orabanda approved mods:


Presently looking at replacing the underslung pilot and brake/tail with LED, which will use perhaps 1W between them, and a halogen, some here have said they use a 50/65W ( or there abouts ), does this work OK, what about at idle ?.

I understand the power rating of the generator is proportional, for a fixed unit, to field strength and RPM.

A 60W generator will not stop generating at 60.01W, It will keep putting out power until it overheats and breaks down the insulation and burns a winding, but must be at an appropriate RPM to achieve said power output.

So what are the advantages of having the unit rewired for 12 volt ?, is there an advantage if one uses the belt mod ?.

My friend and I have both been running our A10's with 12v for the last 3 years
.he uses a tooth belt conversion from SRM .The belt failed after 2000 miles .I think I remember Paul Goff saying this happens.Also, a flange fell off his pulley .I use the Tony Hayward "genration 3" (sounds a bit Star Trek) kit and have not looked at it in 6500 miles.Both these kits raise the gearing slightly.I believe Tony Hayward Now supplies SRM with their kits and you can get them direct from him at a considerably cheaper price .
   We both use "V-reg" solid state Voltage controls from AO services.
  We both agree that not much charging takes place below 30mph and running around town at night drains the battery.
 Hope this is of interest.

Josh, if you are not going to be riding at night, why bother converting to 12V?
If you go back in time to an earlier post you can get the comparison between a standard generator and one which I rewound to 12V.

Isn't the V-reg one of the daft ones that drains the battery when charging isn't taking place?

One flange fell off my SRM drive pulley too and the centre taper died in days despite being assembled apparently perfectly well. Machined it to take the old steel sprocket-centre with its decent taper and it's fine now, but shouldn't have had to. Belt hasn't broken in a few thousand miles. Maybe I should start to worry. If I had my time again I'd buy elsewhere.

Still on 6v with DVR2 and 35W halogen for my A, works well enough and obviously charges from low revs. No discharge into the field coil at tickover per Triton Thrasher's point. Which is a v good feature of Manormike's widget I think. I certainly prefer over the JG and V-reg jobs I've had (at 12v and 6), which are now in reserve. But I do prefer the better illumination from 12v systems (with DVRs) on other bikes as personally I need lights quite a lot for half the year. Have found the combination of E3L at 6 or 12v with DVR extremely reliable over quite a lot of miles. Hardly ever think of Uncle Joe as the Prince of Darkness any more.

No.

If pulleys have fallen off the drive end, I'm probably going to regret drilling the outer threads, guess I'll just have to suck it and see.

Josh,

I'm sorry, please refresh my memory, the helicoiled holes are for a puller?

[Josh Cox]

That's correct, the inner holes fit a small harmonic balance puller, and the outer holes a big one (a little over engineered, I had fun doing it).




Mike, is there any reason I can not pop a rivet in one of the mounting holes, tap it and use it for a earthing point ?,

Trev,
I want to go 12 volt for a number of reasons:
*I already have a 12 volt charger,
*I believe a great number of the engine problems with these bikes are with the Magneto, if this gets under my skin I can go electronic very easily,and,
* Bulbs and batteries are easier to buy.
