Capacitor Between Diode output and Battery

Post by neonwall »

Hi just wondering if anyone knows the reason for this little unit between the positive feed out of diode and before the connection back to feed battery?
I read somewhere that it helps smooth out power delivery to battery is this the case or does it in some way regulate overcharge?
Also next question is, is it required if I get rid of diode board and regulator and replace with modern reg/rec unit?
Cheers

Never heard of a capacitor in that position before. It wouldn't be needed to smooth the power to the battery as the battery itself does that more than adequately. Nor would it regulate overcharge. A capacitor across a power circuit is normally used to control spikes but again I don't see how it's necessary on a charging circuit. Sounds like a mod by a PO. I would just follow the installation instruction for any after market diode board/regulator.

Looks like it might be part of the interference suppression kit fitted to 'official' bikes to reduce interference for radio equipment. Not really necessary whether you keep the original diode boar and regulator or fit an aftermarket unit. In fact, it looks in pretty poor condition so if you've been having charging issues, I'd be inclined to remove this and try it without. You may not need to replace anything.

Like the boots (or are they socks) BTW :D

Haha they do stand out eh, green sport shoes, gumboots got a split in em. Ahh that would probably make sense seeing as it is an old police bike, as you say something to do with radio or some such. Good to know I don't need though, appreciate the feedback gents!
