Do you offer a warranty on your parts ?

Our parts made with high-end raw material, and with strict Quality Control. However, for the customer's peace of mind, we offer a 1 year hassle-free warranty.

Can I install this myself?

We recommend installation by a qualified technician to ensure proper fitment and to prevent electrical damage. Please ensure you follow the provided wiring diagram to avoid voiding the warranty!

Double-check connections and battery health. If issues persist, contact our support team for troubleshooting or replacement options.

Do I need to make any modifications to fit this in my tractor?

No, this is a direct-fit replacement manufactured to OEM specifications, so no modifications are typically necessary.

What kind of maintenance does the alternator need?

Our product is designed to be mostly maintenance-free, but periodic checks of wiring, mounting bolts, and cleanliness are prudent.

dont wire it the way it came out

i am still trying to figure it out, if your only replacing the starter generator you should be ok. if you replaced the 2 solenoids (forward and reverse) with the White Roger replacements (who changed their wiring too) and now they don't match up to the new wiring on the starter. if someone has figured out the way around this, please post it

Great Fit!!

Quick delivery and perfect fit! This starter generator works well on my 1982 Yamaha G1!

Great Customer Service

I purchased this starter/generator for my 1981 Yamaha G1 golf cart. It took me a few weeks to get the time to install it. Upon installing it, I found that it was unfortunately not the correct application for my golf cart. However, even after the thirty day Amazon return window was closed, I contacted Partsworld and explained the issue. They immediately responded and offered me a refund. They truly offer a "no hassle" return policy and in these days when companies rarely stand behind their products, Partsworld USA lives up to their word. I would definitely recommend this seller!

Value for money

Daughter bought it for me. Cart was stalled for too long. Fit perfectly. Comes with installation manual. Very happy with the price!

Three months in and dead in the water, no reply from customer service.

No reply from customer service, so buyer beware...
