Product details
The C3 Motorsport Boost Harness is a heavy-duty jump-start connection for snowbikes, snowmobiles, motorcycles, ATVs, UTVs, and other compatible powersports machines. It is designed to let a suitable booster pack or another battery deliver starting current directly, without waiting for a slow trickle charge.
Manufacturer: C3 Powersports
Why it matters
Cold weather reduces available battery output, and reaching battery terminals can be difficult on a fully assembled snowbike. A purpose-built boost cable makes an emergency start more controlled than improvising with undersized leads around bodywork and electronics. It is useful both in the backcountry and during shop or trailer operations.
Construction and use
The harness uses heavy-gauge cable and high-capacity 200-amp components for compatible starting loads. It must be paired with a booster pack, donor battery, and machine electrical system that share the correct voltage and connection standard. The booster pack itself is separate.
Connection and safety
Follow the C3 and booster-manufacturer connection instructions every time. Before use, verify system voltage, polarity, connector compatibility, cable condition, and the specified connection order. Keep the leads away from exhaust heat, sharp edges, fuel, and moving parts while the engine is being started, and never allow exposed contacts to touch each other or the chassis. Disconnect the cable in the instructed sequence once the machine is running. Store it clean, dry, and protected from abrasion or impact. Replace damaged insulation or connectors immediately, and practice the procedure before depending on it away from the trailhead.
