Glow plugs timer replacment

[6S2344]

I need to replace the original glow plug timer on my Lehman 4 cyl. I have seen
that some owners have replaced it with what looks like an old type Ford solenoid switch?
Close up photos and or diagram would be great.
THANK YOU.

Sorry no photos but I've done the same on my 6.5 GMC diesel. On the heavy terminals, wire from battery and wire to glow plugs on other side. Push button switch to the lighter terminals.

Curious to know the symptoms of glow plug issues. We are having issues with cold starts so guessing our glow plug needs to be replaced. We have a spare but not sure where it’s located to replace. Not sure if we have a timer but if you can share a pic, we can compare. Thx

I think I might have a timer if you want one. I haven't seen it in awhile I took if off my motor. I just put a solenoid on mine with a push button on the dash. Now I just count to seven. Much simpler.
Mary Jo just unhook all your glow plugs. Put multimeter to beep when leads are touched together. Ground the black lead to the block. The red lead wire connects to top of glow plug. If it beeps it's good. Good luck getting them out without breaking them off. Be careful I've seen them use a torch on glow plugs on old diesels. To get them out.
Does everyone's 4d-61 smoke pretty badly when you first start it up till it warms up. Just wondering

I'm a stickler for originality, but when my Lehman 4D61 timer went bad I replaced it with a solenoid. 30 year old marine electronics in a diesel's engine compartment don't seem to last like they used to!

The Bosch timer turns the glow plugs on for 7 seconds. I replaced it with a heavy duty solenoid with a push button switch on the dash and me muttering under my breath "one Mississippi... two Mississippi...".

About solenoids... Google "protection diode". 50 cents worth of insurance.

We found out that we already had a solenoidbut it was just burnt out. It was a lawn mower type and wasn’t able to handle to load needed by the glow plugs. We have since replaced it with a Ford Glow Plug solenoid andazed howquickly she starts again....even with the Bomb cyclone! Thanks for the help!
