Questions About Starter and Auxiliary Relays
How do I confirm the relay matches my original part?
Use the OEM number and pin count printed on the original relay. Send us the number and a photo of the connector, and we will confirm the match before you order.
Are both 12V and 24V relays available?
Yes. Both voltages are covered in this range. The voltage is specified in each product name. Installing a 12V relay in a 24V system will cause immediate failure.
What is the minimum order quantity?
10 pcs per catalogue item. Small trial orders are accepted so you can test a part number in your market before placing a larger order.
Can I mix different relay types in one order?
Yes. Buyers commonly combine starter, wiper, preheat and battery switch relays into a single shipment. Provide your list of OEM numbers and we will quote as one order.
What packaging options do you offer?
Neutral packing with no branding, custom branded boxes with your barcode, or CHINO branded packaging. Artwork is approved with you before printing.
How long does delivery take?
7 to 10 working days on stocked fast-moving items. Production orders take up to 40 days; the delivery date is confirmed in writing when the order is placed.
What happens if a relay fails in service?
All units carry a 12 month warranty from the B/L date. We reply to complaints within 24 hours and provide a solution within 3 days.
