Colt Case Ingersoll Garden Tractors

!!! Starts easy and sounds good! Great job! How the oil pressure? I always get nervous until I see that needle climb!

@Eugen Woot, That has to be a great feeling.

Nice work Eugen. The smokescreen is gone

runs to nice . how you going to keep to mosketoes away now .

sounds good, good job

Nice. Love the sound.

Noel

Thanks guys!

@JSinMO it doesn't have an oil pressure dial if you can believe. It only has a low oil pressure light which never worked while I had it. Haven't run it but for about 30 seconds for now. I intend to fix that light and maybe even replace the oil pressure switch with a sensor later on.

To crank it and start so easy, then just idle with no hesitation is exciting. Cloud Nine! Harry

Well done! A great feeling I'm sure. Sounds great.

So what about thats oil pressure? Thank you Jeff for giving some home work

As you guys know I pulled out some stumps and dug a 100 feet long trench for the neighbour never having any real confirmation of oil pressure or engine cooling. Yeah, sometimes I just pretend it's all working until it doesn't. There now, how's that for a confession?

The truth is I always meant to go through the instrument panel at some point; it's in all kind of bad shape. Found some missing connection which I fixed with some soldered wire, bad light bulbs, etc.
But the real culprit as far as oil pressure goes is the oil pressure switch. That switch should be normally closed. What this means is that at rest, the light bulb gets on one side 24 volts, and at the other end it gets zero volts through the oil pressure switch, which is like a wire connecting the bulb to the tractor chassis which is in turn connected to the negative lead of the battery. When the tractor is running, if there's enough pressure, the switch interrupts the circuit going to open state. Then the light bulb does not light, because it's no longer connected to the chassis.

My switch is stuck in the open state. Easily tested with a multimeter set on measuring resistance. New one ordered.
