Honda fireblade cbr929rr '00 Manuale Di Servizio

START

Count the # of different wire-COLOURS emerging from the RR. If there's a yellow wire on a

Yamaha RR, don't count it (it is a special output-wire for switching the lights on and off)

More than 4

Or if there is no RR on the

bike at all

4 or

less

You've got a permanent magnet alternator system. Let the engine idle, and

connect the black multimeter-lead up to the battery(+). Connect the red

multimeter-lead up to the red (or white-red = Kawasaki) output wire of the RR.

Leave the RR connected up to the bike. Check the reading on the meter. Leave

the engine idling !

VERY IMPORTANT :

This fault-finding chart assumes that the user has knowledge of the basics of electricity (Voltage, current, resistance, etc.),and

about electrical systems on motorcycles in general. If you do not have this knowledge/experience, find someone that has and let

her/him check the charging-system on the bike. The use of this fault-finding chart is entirely at the risk of the user. The author

cannot be held resposible for any damage that could arise from the use of this fault-finding chart.

Fully charge the battery. If the battery is not fully charged you may get wrong results using this fault-finding chart.You could just

replace it with a battery off another motorcycle that has a good functioning charging-system.

Use an accurate digital multimeter! RR means Regulator/Rectifier. This whole fault-finding chart only works if you have a bike with

a combined regulator and rectifier ( = regulator/rectifier) in a single case

Switch the multimeter to DC Volts (DCV or Vdc)

Switch the range to 20 or 50 V. Connect the

multimeter-leads to the battery-terminals. Start

and rev the engine up to 2500 rpm. Check the

battery-voltage

Higher than

13.5 V

Lower than

13.5 V

Rev the engine up to
5000 rpm. Check the

reading on the meter.

Higher than

14.8 V

Lower than

14.8 V

Charging system perfectly OK.

You could still disconnect most of

the connections on the bike and

spray them with contactcleaner

or WD40. This could prevent

problems in the future.

more than 0.2 V

Bad connection in the positive lead from

RR to battery(+). Check the whole lead

(suspect the connectors as well as the

fuse-box and fuses). Good connections

are extremely important in this high

current lead. Solve the problem and

return to START

Less than 0.2 V

Connect the red multimeter-lead up to the battery(-). Connect the black

multimeter-lead up to the negative output of the RR (Honda : Green, Suzuki :

Black-white, Yamaha : Black, Kawasaki : black, other brands normally use a

black wire). If you can't find a negative output-wire, then the casing of the RR is

normally the negative lead to the frame. Check the reading on the meter. Leave

the engine idling !

more than 0.2 V

Bad connection in the negative lead from
RR to battery(-). Check the whole lead to

the battery(-). If the RR doesn't have an

output-lead but uses the case as

connection to the frame, clean the area

where it is bolted and use new screws.

Also check the connection between

battery(-) and frame. Also suspect the

plate on which the RR is mounted

(sometimes it is rubbermounted and uses

an extra cable from this plate to the

battery(-) or frame). Disconnect all

suspect terminals and clean. Best

solution : connect the RR straight up to

the battery(-) with an extra lead. Solve

the problem and return to START

0.2 V

TAKE NOTICE OF THE FOLLOWING :

Suzuki used on the older GS models three different colours for the three output-wires of the stator. They were the only manufacturer doing this.The

only reason for this can be to cause confusion, because the output of all the three wires is the same. The colours on the wires from the stator are :

Yellow, White/blue and White/green. On the Suzuki RR for these models we're talking : Yellow, White/blue and White/red.

JUST THINK THEM ALL BEING YELLOW, and then go on with the tests below
