Time for an update and I need some advice. Still busy with remodel, plus garage has been like 100 degrees when I get home so progress has been slow... So my next purchase was- new front wire loom. No change but now I have fresh connectors and continuous outer jacket. Bought a good Multimeter (Fluke 115) as my two cheapos would get different readings. Rechecked the coil- way out of spec So I figured maybe damaged stator fried it? Got new one, no change but get same reading as original and second one (Troubleshooting guide says 13.2 Ohms across B to C but I'm getting just over 6k Ohms, which is what I believe another member got with his 300RR). Next I look at the stator again. A YouTube video (yes i know...) said if the power output wires show continuity to ground it is bad. So i check the disconnected yellow and white wires and they are grounded. I take the stator cover off and check at the source and sure enough they are grounded and have continuity to the core. But the lights are working and everything looks tight & right, flywheel and pickup coil are clean...So must be right, just beyond my limited idea of how electricity flows. Next check is wire coming from CDI to coil. It has continuity and is not shorted. When I crank the starter I get a fluctuating reading but looks like around .4 volts at the coil connection.
So my thinking now is either power is getting to CDI but pickup coil is bad and not sending signal to CDI to fire or the CDI is bad and was damaged by cranking the bike with a messed up stator. The pickup coil is showing the correct resistance but the CDI is beyond me to test. Other less likely possibilities; 1. Regulator was damaged with old stator (lighting works but not sure if lighting power goes through regulator) 2. wire is pinched elsewhere (I just went out and disconnected the yellow and white wires from stator and yellow wire on the loom side shows continuity to ground but white wire does not.) but I doubt this as the bike was running and odds of two physical malfunctions are high. 3. There is a hump on the flywheel that the pickup coil reads. If it is supposed to be magnetized but was struck by the bolt it may have lost magnetism and the ability to trigger spark.
Last week I ordered a new CDI and pickup coil . I have the new CDI but the Pickup coil is on back order but may come soon. My plan is to try the pickup coil first (only $84
) then should that not fix it install the new CDI. But at $315
I'm leary of unwrapping it as I could probably return it. I'm hoping for advice, even if it's to correct my understanding of the issues involved. Also if someone could check those yellow and white wires on their bike on both sides for ground it could point me in a different direction. If I had advice for others it would be to open your stator/ignition cover periodically as condensation can get in there. A couple freeze/ thaw cycles may have loosened that stator bolt.
