its a blaster II motor in a B1. recent purchase( not mine), had some starting issues and got a new stator as the pulsar coil was thought to be bad. no fix. so now I get it.
have taken the front cover off to check the ground, and resanded where someone else had already. also the other end of the ground where it goes in the ebox.
tested the lighting coil and charge coil. resistance and a/c voltage are perfect.
made new ground and positive cables as they were a little crusty and had the wrong size ends on em.
swapped a new cdi in
swapped a new coil in
bypassed the s/s switch- even thought the resistance is 0.0
checked the ground from the battery end thru the starter, to engine, to cover, to stator, to eboc/cdi. no resistance.
good condition odyssey battery, fully charged.
so as far as I can tell everything is just peachy. problem is with my little spark tester that goes between the plug end and plug when I crank it over most times it goes maybe a half sec or one sec cranking and then sparks, but sometimes it has no spark at all. retry and most times it sparks and starts right up. but every few tries no spark. WTF?
so at some point I lost spark completely and could not get it back. all the while everything is checking out. figure maybe my cdi is bad as I had not installed it until I lost spark. I had a friend bring in his xl 760 and installed the BII cdi in it and the xl fired right up. everytime. swapped in the stator and again the xl fired up. so I put the stator and cdi from the xl in the BII and it starts. swap everything back and the BII starts again. So now I have no more ideas as to what to even look at. take the ski to the water hoping mayne the salt and use will aggravate the problem and make something fail. ski runs fine, IF you can start it. a few times it looked a little like it wasn't going to fire up but did at least 2-3 times. finally couldn't get ti to restart and battery was getting tired. so I think that was it. Once the battery got full charge it fired up fine.
it seems if you start it a few times its fine then like the 3-4 time it skips and then sparks again.
so to recap, 12.8 odyssey battery, new cables, bypassed s/s, new stator, even with a new cdi and coil no start intermittent.
when flushing the ski I was feeling the cylinder temp and got a zapp, so I installed new MSD crimp on ends. but I did try a whole new setup not new to the ski brand new.
I suppose the battery could be old and have low cranking amps, but it will restart after it misses a few times. the starter could be pulling it down extra too. I forget the voltage drop readings I took. the starter looks new(er) aftermarket.
I have read and tested everything I can from the yamaha book and JSS write-up.
anyone have ANY ideas? I will be trying the saltwater in the dark trick tonite on the motor. but I pretty much have hit a wall.:censored:
