ive had my 93' tw200 for over 10 years now and i use to ride it all the time. its sat for the last couple years now and when i went to go start it recently it had no spark. ive changed the oils and sparkplug thinking it was the plug but i guess not. it has good compression and turns over freely, just no spark. anyone got any ideas how to eliminate possibilities to find the problem?

As it is very difficult to diagnose problems like this on line without writing a big essay I would suggest you download the maintenance manual from the link Petrus has posted near the top of this section and go through some of the procedures there. When you have eliminated some areas I'm sure we can all offer you some more help.

well if it stopped working just after removing the switch, YES!


that switch needs to be closed (I don't know how to say it better) for the engine to start.

It's been sitting. Have the mice made a meal of your wires? Best to check as even a small bare spot can cause trouble.

i went through the trouble shooting checklist and these are my results.

i had to use a different pocket electric tester that had wayyy too many buttons and i didnt really understand it. The range button that i was messing with would move the decimal point over or not give me a reading. but at least i got somthin .....



the main switch and the engine stop switch are both good.



for the ignition coil resistance test

primary coil: 1.3-1.9 Ohms i got 2.2 Ohms

secondary coil: 5.3-7.9 kOhms i got 17.5 Ohms ???????





Source coil resistance test

Pick-up coil green-white: 650-790 Ohms i got .835 Ohms ? im guessing its 835?

Source coil brown-red: 400-450 Ohms i got 3.50 Ohms ? im guessing its 350?



the fuse is good



the neutral switch is good



the ignition circuit cutoff is good




the sidestand switch is good



what do you guys think of my results?

The secondary coil resistance is along way out as you have found, the other values are close enough to run I'm sure.

A coil should not cost much to replace but if you could borrow a known good one I fairly confident that you will find thats your problem.
