Thanks for the video!
Took my switch apart and some of the contacts were black.
Sanded them and put some electric grease and works
Perfect now. Goes straight in 4×4 and diff lock right away.
May blink once and it’s in. Thanks!!

I found 501Parts through word of mouth on an internet forum. I gave them a call and I was impressed by their customer service. Very friendly and very helpful. Stephen walked me through the troubleshooting procedures and helped me figure out what was wrong with the 4wd on my grizzly. It ended up being a broken wire. If I ever need to order 4wd parts I’ll definitely be back!

501Parts supplied me with the parts, instruction and great customer service to get my Yamaha going full speed again. In the process they also saved me alot of money.

I am in Nova Scotia Canada, and since I ordered my last parts, you were right on with the time when they would arrive, it was great. You’re the only ones I am going to deal with for my Yamaha needs. Here you got alot of young people working the counter and when you ask a question they look at you like you have 3 heads or they say are parts book doesn’t show. So keep up the great work.

The videos on 501parts are awesome!! I was headed to the dealer to buy a brand new servo motor for $375 until I found out that the unit could be repaired without replacing the whole assembly. I opened the servo and this is what I found. After a call to 501parts, he told me how to clean out the case, I ordered a new servo motor and within a week, it arrived and my 4wd was like new again and only for $55! Thanks!

Just wanted to send a huge thanks for your help tracking down my problem. Turned out to be a badly corroded connector in the wiring harness. Cut it off, twisted all the wires together and taped it up really good. Now it’s good to go! All of your videos were a huge help. I’m not very good with electrical issues and even I had the confidence I could do it after watching them so Thanks again! You saved me a very expensive trip to the dealer and helped me learn a little more about my machine

Saved me alot of money!!

I wanted to send a huge thank you to you guys for this site. I’ve been having issues with my 4wd going in and out on its own, sticking in 4wd, things like that. It’s done it ever since I’ve had the quad. After a hundred or so bucks for a dealership to diagnose, they found nothing. I found your page and started with simple first. When I cleaned the switch itself like your video shows I found nothing to indicate it being the problem. I went ahead and still cleaned and sanded the contacts which loo…
