Guys

Drove the elr to mot last week started no bother and ran there no issues 15 miles.
Problem was when i left mot test centre, bike struggled to start and tick over without conking out.
Drove it back home 15 miles ran great but wouldnt tick over well at lights.
Battery when checked next day motobatt quad battery only 12.3.
fully charged it and it wont go past 12.7 on optimate.
Bought a new yuasa battery 13.3 charger. hooked it up on neg terminal but cant connectto the positive terminal. The positive battery lead is sparking like crazy and melting the lead positive block on the battery. Checked fuses and cant find any issues. Took out the main fuse and still doing the same thing.
Scratch head time.
Any one know what the correct readings are for the rec/regulator ?
or any other thing it might be ?
Appreciate any help its doing my head in.

Thanks

Sounds like your battery is cooked,you should get 13.2 volts on a healthy one,acoss the battery terminal you should ideally be getting14.6 v dc at about 3 k revs.

sounds like the positive lead is earthing out

cheers guys

if the battery's cooked would the rec/regulator be faulty ?
going to check it later.

Any suggestions appreciated

Best to check reg rect with a known good battery,if its the old seperate reg rect best to change to combined unit,i have used the cheapo ones off e bay to good effect,or the ones for a superdream etc work well..

went out to shed and checked new battery now at 12.5
was 13.3/13.4 when fully charged yesterday.

Bike managed to start but when meter attached to both pos and neg terminals
and revving bike to 3 k its going up very slightly (12.8) but not above 13

Does this mean the rec/regulator is fooked ? thought it shud go up to 14 with
a new battery when running. checked and replaced bad bit of wire to pos terminal.

Appreciate any help

Thanks

sounds like it.

should be in the 13.8 to 14.5 range

combo one is the way to go...

This will do the job....Paul J

Have a play with http://www.electrosport.com/technical-r ... ding-guide

Its will point you in the right direction in steps, you are looking at the "Permanent Magnet Alternator system "

Keith that confuses the life out of me,looks like a one way map of London,how you keeping anyroad?

much appreciated guys
went and bought a rec/regular already for £59 off ebay
bugger. no worries.
lights and horn etc all work so hope no alt/stator good

My z1300 had a similar problem i.e battery not charging, the battery and reg /rectifier were OK, it was the block connector from the 3 yellow wires that come from the Stator had melted, i also checked the output from the stator and it was no where near 50+v AC, a new stator from wemoto £65 sorted the problem.

Before buying a new battery etc check the Stator output and connections

I looks pretty daunting Paul but as long as you have an idea of the system on the bike and you start to follow it doing the tests it will get you to a reasonable conclusion and at least save you spending Mega bucks And all is ok here thanks

good point about the stator ill check it tomorrow.


thanks

guys

whats the correct part number for stator/generator from electrexworld ?
confused not much detail on site.
got a reg/rec from them on back order.
bikes a z1000j2 1983 with gpz100b1 engine ?

Thanks
