DC Conversion again

[Spud]

I have just purchased one of the DC Battery rectifier from ScootRS (times are hard & i can't afford to upgrade my stator & go down the podtronics route).

I intend to add a battery in the not too distant, when i have a legshield toolbox fitted.

I would like to use a 12v DC supply for a Horn until i get some cash for the other jobs.
Now,i am sure i read somewhere that if there is no battery fitted, it is recommeded to add a Resistor.

Basically, can i connect the rectifier inline between the output from the regulator & the loom, to run the lights & the horn from DC?
Or should i leave the loom alone & run a wire from the rectifier to the horn?

Finally, when i do add a battery, would this setup give enough power to run the lights & do i need a fuse on the +ve side of the battery or the -ve side.

The set up you have opted for will be sufficient (just) to trickle charge a battery but it won't give enough DC power to power any lights or a horn directly as it will only give you half wave rectification. Having said that, a small battery will store up enough charge to operate a horn.

Cost is about £25 plus a battery if you choose to fit one.

+ cost of fitting & painting legshield toolbox to hold the battery & doing the modification to the stator plate.

I was hoping to use this set up to have a horn that worked, until i can do the rest.

With your setup, does the battery feed all electrics via the loom, or just accessories?
Also which side is the fuse +ve or -ve

It doesn't cost anything to modify the stator, it's a diy job. I set one of mine up without a battery for the same reason as you, a decent horn and brighter more stable lighting and that's exactly what I got

It feeds all the electrics with or without the battery and is -ve earth.

On a full DC conversion all the electrics are fed by the stator (up to it's max wattage), although there will be a small discharge from the battery to fill in the troughs of the rectified supply. So there will be a slight AC effect on the battery feed wire.
When the load is more than the stator max wattage the battery will come into use to maintain 12v.

So without a battery, you would connect the output from the podtronics to the loom.
Do you need to do anything else until a battery is fitted ?
when fitting a battery, is the fuse connected to the -ve or +ve.

Yes
No
-ve

without a battery fitted, the horn will be better with the lights on.
which is probably not a problem, but something to remember at mot time
something to do with the rectifier unit not kicking out much until it is under load...
I'm sure firekdp could explain it better...
