Argh, another dead reg/rec

[whitedevil]

Afternoon,

My bike (CBR 600 F Sport) is killing 1 reg/rec a month for the last 3 months.

1st was the original which was failing when it got hot

2nd was a 2nd hand one off ebay which failed after a few weeks and overcharged and killed my battery.

Fitted new motobatt battery

3rd was a new electrex RR which was fine until yesterday and now only puts out 12v at the battery at 5k rpm and less then 11v if i put on lights.

I've done all the tests everytime each one failed and eveything seems ok.

Checked all connectors which were tight and clean

Disconnected stator

no resistance between pairs

Continuity between pairs but no continuity between each wire and ground.

Started bike

Checked ac voltage at each pair which was 38v on all 3 at 5k rpm.

Should the ac voltage from the stator be higher than 38v on each pair and would this cause the RR's to keep dying?

Thanks for any help on this as its really doing my he

Buy an orginal Honda part, as the first seemed to last a good few years before it went.

The ebay one you can probably say was either close to going or was old, but I dont know what the reputation of the other part you have put on is.

The CBR 600 part has a good reputation, in fact it was usually the one recomended as an upgrade for the VFR 400 as the VFR was well known for frying RRs.

If in doubt fit new original genuine part and give it another go. Then Auto electrician is what I would do.

Buy an orginal Honda part.

 

Have you seen the price of a Rec for an FS

It does seem like like something is amiss there Mate

My mates just had a similar problem on his XT. Turned out to be a crap connection on his starter relay. Dont know the exact details and he's away on holiday but basically he bought a new original regulator but it would still only put out 12V max. All I know is when he unplugged his starter relay then plugged it back in the correct charging voltage returned for a few days then dropped again. He's now changed the relay and 'Bingo' no more problems.
