The Wacker Neuson Spark Terminal Kit is a genuine OEM component designed for the HI 770 XHD Indirect Air Heater series. Sourced directly from Wacker Neuson, this kit delivers the exact specification required for proper ignition system performance in HI 770 XHD diesel-fired indirect air heaters. Compatible across multiple HI 770 XHD configurations — including 1x16, 1x20, and 2x12 duct arrangements — the is the correct replacement when spark terminal components show wear, corrosion, or ignition-related faults.
Key Features
- OEM Ignition Specification: — Manufactured to the exact electrical contact and terminal tolerances required for the HI 770 XHD ignition circuit — ensuring consistent spark delivery every start cycle.
- Drop-In Terminal Replacement: — Connects directly to the existing ignition lead and electrode assembly on HI 770 XHD heaters with no additional hardware needed.
- Broad HI 770 XHD Coverage: — Fits multiple HI 770 XHD configurations, including Arctic Bear XHD, Arctic Bear XHD NS, and Extra Heavy Duty Air Heater variants.
- Sustained Ignition Integrity: — Worn or corroded spark terminals cause misfires, hard starts, and heater lockouts — a correctly functioning terminal kit keeps the burner lighting cleanly in cold-weather conditions.
- Ignition Safety Compliance: — Correct terminal contact resistance and insulation grade are critical in diesel-fired heater ignition systems; using the proper OEM kit reduces the risk of ignition failure or arcing faults.
The spark terminal kit is the electrical connection point between the ignition lead and the spark electrode inside the burner assembly of a diesel indirect air heater. Its job is to transfer the high-voltage ignition pulse cleanly to the electrode so the burner fires reliably. When terminals corrode, crack, or lose contact tension, the ignition pulse weakens or arcs incorrectly — leading to failed starts, burner lockouts, or inconsistent heat output. Replacing the terminal kit restores the integrity of the ignition circuit and gets the heater firing cleanly again.
