DT125R ARCHIVE

Is it meant to be a standard blade fuse though have just googled it and the origional looks like a glass type where as this a standard car fuse and connected using blue crimps is this ok

Will do when I get back from work if the reed restrictor is mossing amd replaced by this fuse does that mean its restricred or unrestricted

Heres a pic of the fuse sorry its not very good didnt have time to take clocks off tonight

 wow thats a new one on me ...never seen that done there or know why .

maybe best option is to lift clocks off and show us a good pic  and maybe what wire they are going to that fuse . have you tried taking it off and seeing what happens ? test bike with iout it see if all lights work or how it runs .

 

Couple of better pics

Hope this helps

Also the red and blue wire further down the loom have noticed it was not connected to anyyhing when I first got the bike but its all wrapped up in insulation tape now so a bit difficult to get a pic

No not yet havent had a chance need to know where the red\blue wire goes though as there is a red\blue wire further down the headstock which isnt connected to anything.from what ive read on google the reed switch is basically a magnetic switch which turns on/off when magnetised.not very good at electrics but presume it must tell the cdi something when the speedo hits 60 dont know if it opens the circuit at 60 or closes it though

after a bit of googling seems the reed switch is a magnetic switch.found this on a site
A Reed Switch consists of two ferromagnetic blades (generally composed of iron and nickel) hermetically sealed in a glass tube. The blades overlap internally in the glass capsule with a gap between them, and make contact with each other when in the presence of a suitable magnetic field. The contact area on both blades is plated or sputtered with a very hard metal, usually Rhodium or Ruthenium. These very hard metals give rise to the potential of very long life times if the contacts are not switched with heavy loads. The gas in the capsule usually consists of Nitrogen or some equivalent inert gas. Some Reed Switches, to increase their ability to switch and standoff high voltages, have an internal vacuum. The reed blades act as magnetic flux conductors when exposed to an external magnetic field from either a permanent magnet or an electromagnetic coil. Poles of opposite polarity are created and the contacts close when the magnetic force exceeds the spring force of the reed blades. As the external magnetic field is reduced so that the force between the reeds is less than the restoring force of the reed blades, the contacts open.reading that it seems the circuit needs to be closed(fuse in) for it to not retard the ignition.am i reading it right..sorry for all the questions but everytime i touch automotive electrics things seem to go wrong lol
Am gonna take it for a blast down the dual carriageway and see what I can get out of it.what do they ride like when restricted through the switch

so it seems then that buy useing the fuse it is turn the swutch off always or is it on always ? all depends on if the circut is closed for on -open for off .

Had a quick search couldnt find it dread.mdk thats what I got to try and figure out only thing is I dont think the red/blue wire is connected to anything so the circuit will be open all the time whats thw difference in riding when its restricted and derestricted as am riding it home from work in about a hour so can see if its restricted or not

there you go :p

Managed to find a wiring diagram for the bike tonight and it looks as though the disconnected blue/red wire goes from the reed switch to the cdiso it seems the bike is running with retarded ignition all the time.strange though cos it seems fairly rapid as it is wonder how much more performance I will gain when this wires connected again.thats another job added to the list

Took for a test ride this morning and bike would only hit 60 on dual carriageway so looks like its running restricted am going to try and connect that wire back up tonight and see if that makes a difference

Dont know have only got two wires on mine and wiring diagram only shows two

Yeh think so where did u get that diagram have got haynes manual but wiring diagram in back is crap
