It didn't take a year. He's set another record in his first 100 days.

Will try and confirm the VIN on the frame but the title says JY43HPW05KC000565. The wire colors on the ATV side of the CDI match the 1990. The wire colors on the stator side of the CDI match the 1988 except that the 4 pin connector is missing the grey wire.

Yeah the switch is like the 90 model. So the atv's plug shape and colour should match the stator's, and they should match the wiring diagram in that pdf "output", where the 90 is the ERA. The wire colours should probably match too, but, I have followed along in here when people have used parts with the right plugs but a wire or two different coloured.

Any of the methods work very well, sand and polish works good but it will need to be kept inside because it will oxidize again if you dont keep it polished. I have found the best way with little maintenance is to go through the cleaning and polishing steps and then clear coat it. I have tried painting and i think it is a good option if you use good automotive quality paint but rattle can paint doesnt seem to hold up. Like i said i have tried it but i prefer the sanding and polishing method. It seems more natural.

When I check my main switch in the off position the ground pair is shorted together and the power pair is open. When in the on position the ground pair is open and the power pair is shorted. Not like in the schematic for the 88 but like the one for the 90. The main switch is original. In fact the only thing that I have changed out is the coil and that is because the secondary was open on the original. This Quad has been in the family since the late 90's and had very little use when purchased. My father used it to get around our property and plow some snow in the winter so has not had rough use and has need very little other than routine maintenance sinch we have had it. Almost done with the carburetor just waiting on Amazon and then will try to get back to the electrical. We will be traveling in a couple of days so it might have to wait until I get back.

Do any of these methods work on high density poly ethaline. I have 1982 husky fuel tank that is all faded.

Ya. Seeing biden in office is like watching Weekend at Bernie's. He a poppet.

If you are referring to the ignition switch, since it did not come with the correct plug and the aftermarket wires are rarely the right color i would confirm that you have it wired correctly before proceding . You still might not be getting power to the CDI but have it correct for other things.

Have you checked the wiring ? Check the stator wires have a good connection all the way to the cdi. Check the kill switch or disconnect it. Check the stator resistance readings from the cdi unit. That will confirm their connections are good. If you tell us the history of the bike and the problem it might help..
