Precautions in handling the glow plug(s)
1. Use the glow plugs only with Universal glow plug controller. If any other type is used, the
heating time will not match that of the glow plugs and cause hard starting and various other
problems.
2. As the glow plugs are in parallel, the controller heating element will turn red even if one of
the plugs is bad. However, the time it takes for the controller heating element to get hot is
less, which will cause the element to burn out.
3. Replacing a faulty glow plug may not solve all the system problems. Should the failed plug
indicate problems to other areas beside the plug they should be checked out also. The
most probable areas are improper fuel injection timing, bad nozzle, wrong fuel, incorrect
circuit connection, gas leak, etc.
