Oil & Fuel Hard Starting 1925 - oil pressure light

[llapanowski]

Today I had a hard time starting my 1925. When the key is put in the heat position the oil pressure light was not coming on. The Glow Plug light is coming on. If I play with it (turn off & try again) the oil pressure light comes on and the tractor starts with no problem. When the oil pressure does not come on then it is very difficult (if at all) to start. Any ideas?

ignition switch? dirty connections on relays, fuses etc.?

Ignition switch would be my guess... Does that unit have a key-off fuel solenoid?
