2003 Mille R Dash/Electrical Reset

Hello,

Before I start pulling my bike apart over the weekend, I'd like to get some opinions on where to start with a slight problem it's developed. The bike is a 2003 Gen1 Mille R, nudging 16,000m.

The problem first occurred during a spirited ride to the Pyrenees, 35degrees C+ on the motorway. Whilst bobbing along, the rev need flicked forward and back, the trip (not odometer)/time/rev light reset and the dash went to km/hr. It has then happend 5-6 times since and is quite annoying!

The battery is about 18mths old now, is regularly charged and the bike has no problems starting. I usually use the bike only on weekends, maybe doing about 70-150 miles on a run out, I did consider that it may be a case of the battery not being used to being hammered over such a long period of time, as much as it was on the euro trip - the R6 that came along suffered a blown reg-rec and a rather swollen battery!

Well, where to start? :confused

1st I was going to check the terminals are clean/tight - then maybe the fuses/starter solenoid - Any help is really appreciated.

Thanks!
 
You need to check what charge is going into the battery - do not use the dash voltmeter as they are quite inaccurate.

One you've established that you have a good charge going into the battery check the earth connections.

Then the diode pack under the round plastic cover next to the fuses (lhs)
 
I have seen an issue where a failing rec/rec can cause something like this. mine was managing only 13.2 volts, but as you rev higher, its output DROPS, this is related to heat.. so perhaps as it was very hot day, at sustained high revs, the regrec was outputting too low, and caused the dash to reset.
 
This is quite a timely thread, the dash on my 2003 bike has been perfect until last weekend when it reset as I turned the ignition on (before I even tried to start it). The bike spun over just as fast as normal when I started it (it's a fairly new battery and it never fails to start well) so it's seem very unlikely this is a charging problem.

Fortunately it didn't lose the mileage, just everything else reset. Couldn't remember how to adjust the shift light so rode home with it flashing most of the way :D

Do the dashboards have a backup battery within them that degrades over time?
 
The plot thickens.

Didn't have time to track down and clean the earthing points.

However, I pulled out the battery, cleaned the terminals and connections that end, removed the tail section (check brown connector) and the left hand tail grill. What I found was this:



Should these be disconnected? I could have pulled it apart accidently, when removing the tail I suppose.... :dunno

Anyway noticed my back brake lights are also on constantly, although they do flicker when the lever is pulled in - I can make them go off by holding it in slightly. Also the horn isn't working properly.

Any more advice? I'm really no expert mechanic and I don't really want to get hit with a big bill. Is it worth checking the earthing points for this? If so where are they exactly? Surely my battery is getting enough charge if the thing is starting fine?

Cheers.

heyhey!!

i hope i can help with this.

Kiwi is absolutly right you need to report back with the actual charging rate on your bike as it site at this point.
the clocks will rest only if theyve lost a permenant batt supply that comes from the ack of the fusebox on the RHS of your bike, if you can let us know the charging rate we may be able to help.

the connector you took the picture is supposed to be apart mate no problem, thos is the diag connector. Your bike has an on board self diagnosticsystem and you activate this by connecting those wires together, so your absolutly fine please dont worry!

let us know!

Thanks for the reply.

Guess I need to buy a multi-meter then! I guess I run the bike and test the battery terminals under the seat? - I'll get on it and back to you at the weekend.

Is the clock resetting fault likely to be linked the the brake light fault, or am I looking at two unconnected problems?

Thanks again.
 
im guessing their two unrelated issues....easy fixes though buddy , nothing to worry about!

stay in touch!

If you find its a problem with the dash unit itself I have a good clean one here fella, orange back lit and showing all but 15k
 
Got home early tonight and had a tinker. Brake light is the microswitch on the front M/cylinder - given a good scrub but the rubber is pretty knackered so will need to keep an eye on it and will be changing at some point. Now assuming the horn is a seperate issue - probably just knackered too.

Yet to get hold a multi-meter, I've given some of the connections a clean - so here's hoping.
 
Ok, so I had the side and tail plastics off cleaned up every connector I could see. Took out the battery and left it on an optimate over night. Went for a run out for an hour and it didn't reset once. Before it would have reset 5-6 times. Where are the earth points exactly?

Measuring with the multi-meter, charge is 13.4-13.8v - is this enough? Could it be the battery, even though the bike starts fine?

So problem seems resolved, but in this case the battery hasn't been chargesd in the bike....

Any advice appreciated!
 
I have a Haga Replica, and if I don't allow it to go through it's sequence of events when I turn on the ignition it will also reset, so I allow the rev counter to go up to the preset level, all the lights to do their thing then I start her up and normally she's fine.

i have simillar issue for years now. i kinda got used to it. just keep the battery charged

Mine lives on an Optimate, so when I'm not using it, she stays fully charged, it's just sometimes I get over zealous and hit the starter button before it has done it's thing.

Additional to cleaning conenctors, I've now added another earth strap to the subframe. I've used the bike a handful of times since my posts last year - with no resets. However, I would like to suckle on the forum's knowledge once more to try and pre-empt any problems before summer (spring for that matter) arrives.

Anyone provide any advice on whether my charge rate is OK?

Using a mulitimeter on the battery terminals, I get:

Off - 11.8v
Idle - 13.6v
4k - 13.0v
5k - 13.0v

Is this expected?

Do I need a new reg/rec? - Brown connector mod?

Cheers in advance!
 
Are these taken with a multimeter? If so, they are quite low readings. Try doing the brown connector mod first as it's no cost, this should improve your readings. If it doesn't maybe look at the reg/rec.
Just info I've scrambled from here and rsvr.net, my readings are considerably higher though.
 
he was using a multimeter.

for low readings i reccommend doing the plug mods AND an additional earth. :) well, i'd reccommend changing the RR to a mosfet one too! :)
