HD Switch 6-Pack 12V 40A Waterproof Relays 086-1201-00 with LED Indicator, IP68 Sealed & Dielectric Grease

HD Switch 6-pack 086-1201-00 are IP68-sealed 12V, 40A relays with integrated LED indicators designed to replace OEM relays on Bad Boy lawn mowers and similar equipment.

These relays combine heavy-duty contacts, a visible LED status light for instant diagnostics, and a fully waterproof housing so you can install them in exposed engine bays without worry. The set includes dielectric grease to reduce corrosion at terminals and improve long-term conductivity, and the form factor matches common Bad Boy relay sockets for a straightforward swap.

How do these relays simplify troubleshooting on my mower?

The built-in LED lights provide immediate feedback when the coil is energized, so you can tell at a glance whether a relay is receiving control voltage or if the issue lies elsewhere. That reduces time spent tracing wires or pulling components.

• LED indicates coil activation for fast fault isolation
• Standard 40A contact rating for common mower circuits
• Included dielectric grease lowers terminal corrosion risks

Are these relays durable enough for outdoor and heavy-equipment use?

Yes. The relays are IP68-rated, meaning they withstand immersion and are protected against dust ingress, which is ideal for equipment exposed to wet grass, mud, and dust. Robust internal contacts and a sealed enclosure extend service life compared with unsealed replacements.

• IP68 fully sealed housing resists water and debris
• Heavy-duty 40A contacts for high-current loads
• Designed for lawn mowers, tractors, and work equipment

Will they fit my Bad Boy machine and are they easy to install?

These relays are designed to match the common Bad Boy relay spec (086-1201-00), so they plug into existing sockets without modification. Installation is straightforward—pull the old relay, apply the supplied dielectric grease to terminals, and seat the new relay into the socket.

• Direct-fit replacement for 086-1201-00 style relays
• Plug-and-play: no wiring changes needed in most cases
• Dielectric grease included to protect connections after installation

What electrical loads and applications are these relays suited for?

The relays are rated for 12-volt systems and handle up to 40 amps, making them suitable for starter circuits, PTO/clutch controls, lighting, fans, and other medium-to-high current accessories on mowers and tractors. They are not intended for continuous higher-amperage industrial motors beyond the 40A spec.

• 12V system compatibility for typical small equipment
• 40A contact rating for motors, lights, and accessories
• Sealed design for exterior and engine-bay mounting

Who is this for? If you maintain Bad Boy mowers, compact tractors, or heavy-duty outdoor equipment and want a reliable, weatherproof relay that makes diagnosis quick and reduces connection failures, this 6-pack from HD Switch is made for you. It’s especially useful for service shops, fleet managers, and DIY owners who prefer direct-fit OEM-style replacements with the added benefit of LED troubleshooting and corrosion protection.
