ZXR 250A Rectifier replacement ????

Post by Kwakka Kilt »

Och Aye All ! :D

Whaddya reckon guys, I need to maybe swap out the rectifier / regulator on my wee beastie, and was wondering if this one would work as an alternative ??

http://cgi.ebay.com.au/ws/eBayISAPI.dll ... :IT&ih=002

(It's cheaper, suits me being a Scot ! :wink: )

I'm not bad around a soldering iron, so I can make good joins with the cables, but is 35 Amps a high enough rating for a bike regulator ?

Other thing is, I can't find a regulator for the ZXR250 anyway, so if this works it's smiles all round ......

Cheers.

it'd do the job just fine, just make sure that its in a place with enough air flowing over it, ... or just hook up a pc fan to the ignition and attach it to the heatsink :D

dunno mate... dunno wot the stats on a factory one are... only problem is if its not right, ull be up for fuses (cheap) a battery ($30-70) possibly a stator $300+ (cbr ones are $600) if it causes problems...

Thx guys, yeah was worried that I would melt my loom !! :evil:

But I reckon a rectifier only screws your circuit if the diodes go into meltdown, shoving full bore battery power down the nice thin cabling .... :shock:

I'll see if I can track one down, if not might not have a choice ......

Watch this space :D

Just having a look at my zzr 250 manuals which has these specifications:

Charging System

Type: Three-phase AC
Charging Voltage (regulator/rectifier output): 14.5 +0.5/-0.5 V @ 4000RPM
Stator Coil Resistance: 0.2 - 0.9 Ω (I think that stands for Ohms, please correct me if i'm wrong)

Anyway I hope this helps.

Cheers

Thx for the info Ben, Just managed to get a rectifier from another KSRC member, awesome :D

Going to mount it in the next 2 weeks, give the battery a good charge up, and see if the battery is getting around 14 volts charge once running.

Fingers crossed, had enough bump starting the wee beastie :evil:

Stu.

Took off the rectifier couple of weekends ago, blackened / charred pins, and one half melted plug to the loom - Defo a rectifier on meltdown !!

Thank Gawd I caught it in time, have heard of looms going into meltdown in worse cases ......

Thanks for all your help.
