Got no spark on my gear up 2008   Replaced Hall, coil and CDI unit .  Still no spark   the kill switch seems to be working as the battery light is on   had 12 volts at the cdi unit too. was not able to get a good reading at the two coil wires   Has anyone taken a reading on the voltage there?   The reading on the hall show with in range.. 2 v to 5 v high.    Tomorrow I going to take new readings from the new parts and see what they are.  Any ideals would be help full.

today metered the new CDI Red  to Black  10.85 v  Red to Green  3.46 v   hall with metal  10.68 v  R to G; R to B
old  CDI   4.67v     0.37

both grounds show good    Coil and CDI are grounding. tested the wires  between  CDI and main connectors for breaks; all good.

Used a screw drive to operate hall sensor for readings along with jumpers wires for metering at the connection at the front of the bike.

Check how much voltage is getting to the ignition ..on my 2005 if it didn't get the full 12.5v it wouldn't work ..once i sussed this it could put the meter on it and wiggle around till i noticed a change and then fix

Just got back from an acquaintance place...had a no Start condition...I had asked him the last couple days about his Battery...he Insisted it was OK.
When I got there it was sitting at 12.2V. Nearly Dead...
I explained to him that 12.0 V is Zero Percent Charged, 12.3V is 50% charged, and 12.6V is about 100% charged...
New battery cured his woes!!!!

What does your measurement say to You??

Wish I had the Races back that I lost due to a battery that measured Good without a load, and Less than poor with any load on it!!!

Changed out with all new parts    Problem can back on short ride to town and back Engine just stops cold, cranks but no spark   This time I poked at the wires on the main plug on the CDI unit one at a time  the whte one seems to be the problem one  , it seems to be causing a make or break connection    .move it and the bike starts  move again and it stops.  So changed out the wiring harness. Now runs good.  Wonder it that was the problem all along.   or was  it two problems making it hard to fix.   the old CDI power to hall was lower that the new CDI.
