This morning, I was getting ready to fire up the L210, and while I was holding the switch in the "glow" position, the glow plug indicator in the dash turned red, and then faded. Of course the tractor would not start.

I checked continuity in the circuit with a multimeter, and found it continuous, but apparently intermittent. Also, when I activated the switch I was getting .5-2.5 volts across the glow plug indicator. Battery indicated full 12 V.


I figured I might have a failing glow plug, and was ready to swap in the plugs from my donor engine. Preparing to do so, I noticed that the knurled nuts on top of the glow plugs were a little loose. Both of them. I tightened the connections, and tried the glow plug circuit again. The indicator coil lit up more quickly and more bright than it had been and the tractor fired right up.

Problem solved, it seems.
