C-145 Auto electrical problems

[Kid with a wheelhorse 2]

Hi all I have recently acquired a C-145 automatic and it is in good mechanical shape but it does not have spark I have replaced the starter coil and magneto coil as well as the key switch and the solenoid and eveything is up to spec what should I do

When replacing the key switch, did you replace it with the correct one. There is a difference between a switch for a magneto ignition, and a battery ignition. However, you said you replace the ignition coil and the magneto coil. There can only be one or the other. A magneto system has no ignition coil and vice-versa. So lets try to figure out what you have. Do you have the ID number for the C-145? What is the year? Which engine does it have? Do you have the spec number from the engine? I'm sure we can get you going if we have the right info.

It is a 1-14259 and I replaced the switch with a 5 pin 3 position should be a 1980 model year with a k321AS and spec is 60362d

That spec is a battery points ignition with a 15 amp Stator for charging.  The regulator you have sitting loose is not the correct one.. The finned one mounted on the hoodstand is.  Run a jumper from Battery+ to the + terminal on the coil crank it and see if you get spark,

I have gotten power

there when I was working on it

If you had power on the coil and no spark next thing is points... Make sure they are opening and closing and clean them up...

C-145 has a fuse taped into the wire harness in the area between the starter and regulator. Check that for the heck of it

Fuse is fine and I cleaned the points

Disconnect the condenser and try

No change, would the spark plug cable cause loss of spark

The tractor model number is not 1-14259/

Will guess it is 01-14KE01 if the transmission filter is at the rear of the tractor

or model 01-14KS01 if the filter is on the right side of the transmission.

They changed from Sundstrand hydro's to Eaton mid-year 1980 and why the use of E and S in the model number.

It’s the second one

It sure could  also is the plug new.  You might want to steal a Plug wire and plug from a working tractor if you have one.

[Kid with a wheelhorse 2]

Cleaned and gapped the plug put a new wire on it to still nothing

if you have a test lamp hook it between the - terminal on the coil and battery positive... by hand slowly turn the engine over  the light should turn on an off as the engine is turned over.
