How does the ignition coil work in a CDI?
In a CDI ignition system,a storage capacitor is charged to a high voltage (a few hundred volts) by the flywheel charging coil and, at the proper moment quickly discharged into the primary winding of the ignition coil,which is actually a stepup pulse-transformer. The secondary output is a short very high amplitude pulse which fires the spark plug.
What kind of voltage regulator does Polaris ATV use?
It is manufactured using high-quality materials, to the same specifications as the original part. Voltage Regulator for many 94-97 Polaris 400cc, 425cc & 500cc models ATV. This part is aftermarket equipment designed to replace the original manufacturer’s part numbers specified here.
How does the spark timing on a CDI work?
The spark timing is controlled by a small trigger coil located in close proximity to the flywheel which generates a low voltage pulse (actually two, a positive and a negative one), as the fly wheel magnet passes by.
What kind of compression do I need for a Polaris coil?
As a suggestion, run the engine until you do need an upper engine rebuild. Instead of buying new rings, one could buy a new upper end kit. For example, 53 MM kit with 145/150 PSI compression. I installed a kit from Billy Holt at WRH Racing.
How do you test a Polaris stator coil?
It’s a actually one wire that runs round and round all the posts, and back to the begining. All you need is some sort of test meter, or digital volt ohm meter. Put it on the continuity setting , and touch a lead to each wire.
When to pull the stator on a Polaris Pred 90?
If your PRed-90 has some “down time”, I’d pull its stator assembly and give it a good cleaning. Less mud / crud means less heat build up. Thus, making the stator last much longer. Also, don’t forget to install a 10 Guage wire from the “-” battery post to the frame. And another 10 guage wire from the frame to the engine.
What should the PSI be on a used Polaris?
Actually, 100 PSI great for a used engine. 120 is fresh, 100-90 is running average, 90-80 is too warn and 85-60 is “buy the needed parts now”. If pure stock engine and PSI is 100, I’d leave it “as is”. As a suggestion, run the engine until you do need an upper engine rebuild.
