Sounds like you may have two defective phases in the generator.

Rare but possible.

 

Correct me if I'm wrong But..., if you try to get a reading from the Alternator wiring block while it's
disconnected you will get NO reading, the 1000f needs this to be connected to send power to the Rotor, this block also has the black and white wires which are the power feeds to the Alternator

 

CBR1000F alternators are old school permanent magnet versions and only use a three wire connection to the R/R. The three wires are all normally yellow.

They are not the latest generation electromagnet versions as fitted to some other bikes.

When the engine is running there should be around 26v AC between any two of the yellow wires.

 

I have a 96 CBR1000F , I there are 5 wires to to Alternator, in 1 block, 3 yellow and a black and white,
this will make it an electromagnetic Altinator, correct?

 

% wires to the alternator plug OR 5 wires to the R/R plug ?

If there are five wires going down to the generator case then yes it sounds like an electromagnetic unit.

That is an odd one - never seen an electromagnetic on a 1000f.

Even the blackbird is still on a magnetic altenator.

EDIT - I guess you have 7 wires to the R/R ? - 6 in a block + 1 earth wire ?

 

Hi, Deano, Yes I do have 5 wires to the Alternator plug, and yes a 7 wire R/R
The wiring diagram also shows 5 wires, this is a 95-6 CBR1000F, just to make sure we are talking about the same bike
BUT...I is having a charge problem with this also, I'm working on it.....
cheers

 

Ok guys, .........
having a serious charge loss here. usual story huh I have a good battery, and a new aftermarket R/R, in fact I have 2, I get them cheap.....
have pulled the Stator off the Alternator, nothing burned or visual defects, all looks nice and pink inside..
have checked the continuity between all wires at the Stator plug (pin to ground), all good, so no short
have checked the ohms at the 3 yellow, all read 0.00 ohms (yellow to yellow) supposed to be 0-1.0 ohms..within spec ? debatable...but all read the same....
Start the bike and check charging A/C Voltage at the connector.. all yellow show 0.2 A/C Volts.....bugger..
Here's the weird thing.....both black and white now read 26v A/C (connector pin to ground)

WT... is going on here.......looks like there may be a short in the Alternator somewhere after all????

I picked this bike up cheap, it had been nicked and recovered, the ignition was ripped out and had some other ignition switch hooked up, so that has also now been replaced with a new one (aftermarket) so it's a project bike right now,
