SOURCE: 83 yamaha tt600e no spark
The CDI unit on the 83 model (TT600) is located under the fuel tank and suffers from heat
exposure.The solution is to get specialist help to open up the sealed CDI unit and repair/
replace internal connections (which are readily available electronic components)
When you re-install it put some heat shielding material there to protect it and this
will be OK as repair will utilise stronger parts,I think.
Later models have the CDI unit moved to the head-stem area.
(this info from a Non-mechanic who remembers what was done to his TT in Australia, many years

SOURCE: No spark
Check the side stand kill switch if your bike has one. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it. Check the fuses. How good is the battery? Try a jump start from your car battery. Is the handlebar kill switch on? Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Install new spark plug.
If that doesn't do it, check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center casing. If still no spark, get CDI system and coils checked at the dealers shop. You can screw up a CDI unit checking it yourself.

follow the plug wire back to the coil and see if there are any breaks, if not might switch coil with the other one and see if the other plug now misfires, if so replace the coil, most cdi problems are not intermittent, typically they either work, or they dont.
