Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
Compatible equipment / model
- Yanmar 3TNV88 diesel engine applications
- Solar / Bobcat SL75-V applications using HC0119
- Excavators and industrial machines with timer 129211-77920
- Additional equipment only after circuit and connector verification
Product Overview
A shutdown solenoid that does not receive the expected timed command, a machine that will not complete its key-off sequence, or unusual preheat timing may lead to this module after the relays, power, grounds, wiring, and solenoid are tested.
Depending on the host-machine circuit, HC0119 may be described as a flameout, shutdown, or glow timer. The part number and wiring diagram—not a seller label—should determine whether it is correct.
Match HC0119 and 129211-77920, connector pinout, case, mounting, voltage, engine, equipment model, and serial number. Never swap timer modules by plug shape alone.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application that is not shown above. Model year, production date, serial number, engine or equipment specification, installed options, and previous repairs can change fitment. Match the original part, reference number, dimensions, connectors, mounting points, and product photos before purchase.
Frequently Asked Questions
Q: Is this always a glow-plug timer? A: No. Host-machine circuits may use or describe it differently. Confirm the wiring diagram and original module.
Q: Can a bad shutdown solenoid damage the timer? A: A shorted load or wiring fault may overload the control circuit, so test it first.
Q: Why is this similar to another listing in this batch? A: Both products cross-reference the same module number but may have been sourced for different machine-search terms; fitment still requires the exact circuit match.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
