sico Posted April 25, 2008 Share Posted April 25, 2008 I had my dt 125 stolen and the thieving scroats smashed my lights, clocks and ignition off. After much searching I have found some new clocks but there is no reed switch. They cut the old one off. Do I need one or can I just twist together the red / blue and the white/black wires together? Should this be an open or closed circuit and is there some resistance in the switch? cheers Sico Link to comment Share on other sites More sharing options...
mckenzie Posted May 1, 2008 Share Posted May 1, 2008 i think the reed switch on the older dt's restrict the top speed, im unsure of the wiring but you can always buy a Haynes manual if you can read wiring diagrams, also check out this site.... http://dtr125.net/ Link to comment Share on other sites More sharing options...

I had already been to that site and as you say it is for de-resticting the bike but the advice they give you is to move it away from the clock but not to cut the wires. The wiring diagram shows it is fed from the CDI unit and returns to the servo. It also shows it as an open circuit on the diagram but I think that is just to show it as a switch. It gives no detail as to any kind of resistance when the switch is closed circuit. What makes me curious is the fact that all sights that show how to de-restrict a DT 125 all say dont cut the switch off. Regards Sico Link to comment Share on other sites More sharing options...
mckenzie Posted May 4, 2008 Share Posted May 4, 2008 I was wondering about that myself, my bike is an 06 dt125x, to stop the valve retarding after 7000 rpm you have to earth a wire to the frame which made a difference, but I wanted to put a variable resistor between the wire i have earthed and the connecting block that it origionally was wired into to see if it made a difference, but as you say theres no mention of a resistor in the circuit. The effect I was looking for was to use the variable resistor to switch from power and standard mode. Do you think it would work?? Link to comment Share on other sites More sharing options...

It probably would not be a good idea to fit a variable resistor unles you can get a weatherproof enclosed version and set the level before moving off. If you are looking to switch between the 2 you maybe better with just a toggle switch. I am going to try fitting a reed swtch to the bike but use the type they have on alarm door contacts to see if that will do the job. Sico. Link to comment Share on other sites More sharing options...

Sico. yeah i think a toggle switch between 'full power' and standard would work ok, im sure a variable resistor would work but i could end up frying the circuit!
