DIY Regulator/Rectifier?
 

Just been quoted £185 by a Suzuki dealer for a K3 Regulator/Rectifier :smt088

Has anybody ever thought about using readily available car parts to piece one together at a fraction of the cost?

Regulator here: http://cgi.ebay.co.uk/LUCAS-ACR-ALTE...item4836193b26

Rectifier here: http://cgi.ebay.co.uk/LUCAS-ACR-ALTE...item48352cf94c

The diodes on the reftifier are rated at 45 amps, so should easily cope with output of SV650 alternator.

Any thoughts?

CBR600RR reg rec... £40 or so on ebay and bolts into same place

09 Fireblade one, doesn't bolt in the same place (bigger) but under the seat and does a cracking job, about 40 quid as well

SV650 Curvey RG85
SV650 Pointy RG851 (aparently but i guess the RG85 should work fine)

cheep new and the best option rather than playing around

Re: DIY Regulator/Reftifier
 

very true and a simple option, never knew that place existed but at 67.40, i'll stick with the 35 quid fireblade one and about the 5 quid of bits. However if you don't want to play and have the cash it's the best options. nice link TSM.

last one I used was from a GSXR. plentiful on ebay. I got mine for £10 plus post

Trick is buying a rec/req off of Ebay that works though. Some unscrupulous sellers may just out their old knackered one :(.

Certainly a tenners cheap if you get a result though :)

Re: DIY Regulator/Reftifier
 

This is fine - if you buy one that works.

More than once an owner has brought me a bike that doesn't charge and which has had the regulator replaced with a second hand one - which doesn't work either.
Now this may just be a coincidence, but the regulators in such cases have been those usually fitted to Hondas.
The unfortunate assumption that Honda regulators are angels breath and must be an improvement his proven incorrect. Or peharps it means Honda owners are unscurpulous thieves?

Discuss

Anyway, whilst I have often fitted S/H parts to peoples bikes, (at their request only), for many people a new part is a better and more certain option.

The car part method may not work. Turns out bike alternators use fixed magnets, whereas car alternators use electro-magnets, I believe the voltage regulation works in a different way.

Yeah, car alternator uses a field coil so you only get as much charge out as you need. Bike alternators run all out all the time.
