The 23C engine has four glow plugs, one for each of the four cylinders.

They are specified in the MF manual as
- LODGE D.T. 14 L-1.7V (1.7V - 38A), or
- KLG GF. 205.T (1.7V - 38A)
Both of these seem to have been discontinued, or the manufacturers are no longer in business.

Currently I have three KLG and one Lucas/CAV plugs (the Lucas/CAV is the most recent):

The ballast resistor unit up to S/N 156502 is KLG Z. 174/1 (3.7V - 36/40A)
and after this serial number, KLG BRQ. 1 (3.7V - 38/42A)
Again, these resistance coils are probably also obsolete and unavailable.
     My coil broke a few years ago and I had it welded up. However, it recently broke again—in the same place as before—so I made a brass clamp (see below) which ties the two broken ends together. This works until a new coil can be found or built. I am presently corresponding with a person who can build such a coil, and will post any progress we're making.

The glow plug pilot lamp in my FE35 is an Osram (England) bulb, 6V and 3W (see below). Up to S/N 156502 a 12 volt bulb was used, but later a 6 volt one was used. Apparently the 6V bulb can be used with either. This bulb may also be obsolete and unavailable now.

If you have any ideas for replacements of these old items, please let me know and I will post them here.
