Hello!
I have a DF15 from 1997 with no spark. One day it suddenly just died when It was running.
The spark plugs are replaced. I found a service manual on the internet for models 2003- (so its not really the right one for mine). I did however get some ideas what to check. I also disconnected the engine emergency stop switch to make sure that isnt the problem.
I checked the condenser charge coil. Resistance = 461 ohm. Output about 114 volt AC (when cranking the engine, I got an electric starter). The manual says 144 volt and 244-364 ohm. But since the manual isnt the right manual I cant say for sure that the outcome is out of spec.
I checked the pulser coil for resistance. Resistance = 210 ohm. Within spec. Will also check the output voltage tomorrow.
What I also checked was the output from the CDI to the ignition coil. There are 2 cables from CDI to the ignition coil. I measured on both cables (one at a time) and ground and the result was 0 voltage, checked with both AC and DC.
Even though the output from condenser charge coil may be out of spec, I should still get atleast some output to the ignition coil?
I just dont want to buy a new expensive CDI until I am sure that the CDI is the problem.
If any of you have any idea what to do next please let me know! Ive checked the wirings+connections and cant find any obvious problems with it (corrosion etc)
