Wiring schematic

Has anyone seen wiring schematics for the RK 24? My preheat quit working and I have no idea where to go after the fuse block. The fuse is good.

I had a very similiar problem with my RK 24 where the glow plug light on the dash would not illuminate and the glow plugs would not work (no preheat cycle).
I cleaned the contacts at the preheat relay (middle relay in a group of three located on the r/h side of engine above the oil filter) and the contacts on the ignition switch. It has worked fine ever since.
The schematic that you need is for the TYM T254 series. Don't remember the full number but is the TYM version of an RK 24.

Thanks that is start. I'll see what I can find with h relay and TYM model
