Have a freind who picked up a bike pretty cheap and i was trying to help him out. Here goes. It was not sparking at the plug and after checking it out it appears that the previous owner had removed the wire from the coil and it don't seem to be with the machine. What color would the wire have been and where would it have plugged onto the power distrubution board? Also will a 85-88 model 250 r/es trailboss starter interchange with this model? I had browsed some earlier topics and and also was wondering on the cdi box that of the 2 black wires that come out and go to the board of which one would be the kill switch one? One is short and on the left side of the board and the other is long and on the right side of the board looking at the front of the bike, i am suspecting the long one but just thought i might get clarification on this.

 

Any where to get a wiring diagram or schematic maybe?

 

any info

 

Should be one black wire from cdi which is tied into the kill switch and,one black wire from the reverse module that plugs into terminal board also.

 

i have 2 wires and they both go to the terminal board but nothing to the coil. I could make a wire but don't know where to plug it to the terminal board.

 

Cant remember color codes from the old machines,but wire from coil should be a blue spade connector? that comes from the stator harness NOT from the terminal board!

 

I have checked all over the harness and there is no blue wire. I have found terminals on the board that when you pull the recoil i have strobing current and it is marked for a yeelow wire with a red stripe. The terminal strobes even if the kill switch is in the off position too. Tried the lond black with a whute stripe from the cdi plugged to the coil and nothing there.

 

I put a wire from the terminal that pulses o the coil but when i do this there is no strobing current which has me thinking that the coil is bad. How do i check a coil? I have a ohm meter but what would be a passing reading?

 

Kinda jogged my memory when you said black wire with white stripe! this should be coil wire if I'm not mistaken. yellow/red wire should be for reg/rectifier charging. Ignition switch or emergency switch off and still have current to yellow/red wire? If ignition switch off and still have current,then suspect switch. On emergency cutoff switch on older models it would just kill power to ignition only, would run batteries down,thats why new machines emergency switch kills all power to save battery. hard to visualize what has happened unless wires have been cut!

 

IF ALL ELSE FAILS try to talk dealer into printing copy of wiring schematic! I do for a lot of doityourselfers!
