Hey!
Well, that manual isn't properly the same as my engine..at least not for the year in question...
In sum, there was a guy here today that came with the YDS (yamaha diagnostics system)..
At first the program didn't let him do any tests because it kept saying the engine was not in Neutral..
We tried a new 703 control box but error was still there...
We found another switch under the R/N/F sliding mechanism and with a screwdriver we were able to press it.
After this he could some testing.
We were able to test 2 ignition coils at a time with the YDS software and all 6 had spark!
Tested both fuel pumps and they passed the tests.
But still the engine won't start with the key.. it turns but there isn't spark on any of the sparkplugs.
We suspect it is the pulser coil that is not working.
How do I test it properly?
I tried resistance testing between B & W/B, B & W/G, B & W/R and had infinity.
Tried between W/B & W/G, W/B & W/R and got around 1005 ohms (just over 1Kohms)... manual says it should be between 400ish and 500ish.
Could that little spark I mentioned have burnt the pulser coil?
