Lost Spark
Posted: Mon Oct 07, 2013 3:56 am
So I've had a bit of fun with my 1988 KR-1B........
Rode it around for 150 Kms yesterday. No issues.
Jumped on it to run to the shop yesterday afternoon......Tooling along slowly turning about 4-6,000 rpm and poof. No more Spark.
Everything else works. Headlights turn signals, Kips Motor etc.
Trouble shooting till Blue in the face.
Coil - .3 ohms on the primary, 4.7 kohms on the secondary (right on Manual spec)
Exciter windings 150 ohms White to Black and Red to black, 4.7 ohms White to Red.
(there is no manual value for white to black but I'm assuming that 150 ohm would be in the acceptable range)
Diode checked 1-2, 2-3, 3-4 within manual spec.
Pulser (Pickup Coil) - 123 ohm
Grounds checked, Ignition switch checked (white - Brown, Red - Red/white), Positive power to the CDI.
Only thing I can figure is the CDI has given up the ghost.
Anyone have any ideas? Anyone ever disassemble the CDI for inspection trouble shooting?
Anyone got a spare KR-1B CDI they want to sell? Its the 21119-1234 unit.
Anyways.....very frustrated in Oz
