Hello out there. Not been on here for a while as I have been busy with surgery on my hand. Been running my husqvarna 610 for a year and it's brillant until the other day I was out and the bike died with no electrical power. Got the bike back to my workshop and stripped it down and found the ground lead from the battery had backed off. Crimped on new lugs onto the cables as they didn't look brillant. Battery back on and power back on. Went to start the bike and it just spun over with no coughs. checked for spark and got the faintest spark, so checked the system and everything is supposedly in spec. Only thing I can't check is the cdi. Well I made up a test CDI for my old 610 using a lifan 250 digital cdi and wiring harness that i kept when sold the other bike. Dug it out my toolbox, plugged it in and the bike fired straight up. Tuned the bike and the bike runs but it's not the BANG the bike had which i assume is due to the ignition curve on the CDI This seemed to look as the old CDI got spiked. I have since purchased a "new " cdi that has 3 ignition curves on it (switchable). I plugged it in and got nothing again. Plugged in the lifan and bang, bike fired straight up. So this means I have 2 duff CDI's OR the lifan CDI can produce a bigger spark from less juice from the ignition. Just wondering if anyone who has a running bike can chuck a multimeter at the bike and give me the relevent specs for resistance, voltage output and anything else they can think off.
