Product Overview
The relay supplies high current to the glow plugs during preheat. A failed relay can cause hard cold starting or no glow-plug voltage, but worn glow plugs, a failed timer/controller, wiring resistance or low battery voltage can produce the same symptom.
Yanmar documentation identifies 119650-77910 as a glow relay on multiple 2TNE68 engine variants. Marketplace listings also associate this relay family with some Komatsu mini excavators, but machine fitment should be confirmed from the engine plate and original relay number rather than relying only on the excavator model.
