Electrical Problem with a 2001 700 SKS Liberty motor

I have a problem with my sled. I took it out of storage and when I start it up, the lights are flickering off and on. I am guessing I have a bad ground somewhere. This is impacting all the lights. Does anyone know where I can find the ground going from the motor to the frame on this snowmobile? I tried cleaning up the large white clip and I thought I had the problem fixed but it is still doing it intermittently. Any help would be really appreciated.
Thanks!

Some additional details on this problem. I attached a voltmeter to the yellow wire coming out of the stator. I plugged it directly into the clip and attached the ground wire to the head of the cylinder. I then fired up the sled and it reads about 13 Volts AC. When I accelerate the volts actually drop a little but the lights stay nice and bright. Then after about a minute or two of running, the voltage drops down to about 4 and the lights barely glow for a little bit. There is flickering back to full brightness during this time. Then once the motor runs for a bit, I can't seem to get it to do it again. My question is do I need a new stator or is their a possibility something else is wrong? I just changed the stator last season because I lost spark. I put a used one on though. I didn't notice this issue last year but I only rode it once after the stator was installed. Is it possible I could have corrosion on the stator? Could I have put something back together incorrectly? I am tempted to buy a new stator but I really want to make sure I didn't do something wrong. I also don't want to put a new one on and have the same problem. Any help would be appreciated. Thanks!

The voltage regulator may be taking a dump. Good news is they are usually really cheap!

Could be corroded flywheel magnets/stator, bad lighting coil, or voltage regulator
