Service Manual for Craftsman Tractor 18HP 44" Deck
Anyone know where I can find some service information on:
Craftsman Tractor 18HP 44" Deck
I searched their site. They have part list and some other diagram. However, the engine part missing. I couldn't find the engine's make and model on the engine itself.
The diagram is shown in a very low quality image, and electric wiring doesn't have color code, or any pin out for any of the components.
I also need tune up spec (such as gap/length information for engine, battery charge rate, et).
Search the site above, and it say not found.
If free is not an option, then where can I buy a manual for that model? If not available, how about a model that is close to that one?
I need a manual because of a problem with this tractor.
1) It does run, so I tested the spark, and there is spark. Then I tested the fuel, and found out that if I put some gas in the air filter then engine would run. So it's gas problem.
2) The above action happens a couple hours after I pressure wash the tractor (it didn't work before that, just to say, that it does start to run after the wash).
3) I let it sit for a day, came back, and took out the fuel pump and the carb and clean them up. Put back and turn the key. Nothing. Not a noise.
So, I think because of washing it, and let it sits, something screw up the electrical.
I short the Battery + to the small connection of the starter solenoid, and the engine crank up. I measure connectivity between that terminal of the solenoid and the starter electric + cable, and there is no resistance. This is confusing. I thought this terminal is excited, and makes a path between battery + to the starter cable. Here, if this terminal is connected directly to the starter + terminal, then what's the point of the solenoid. I thought the solenoid is like a relay.
From my test of shorting battery + to the solenoid small terminal, and the starter crank, would that mean the solenoid is good?
if so, then there could be problem with some of the safety switch.
When troubleshooting electrical and tracing through wires, do you cut off most of the ties? If it's bundle, it's so hard to trace. (ties == the wire or electrical tape that ties the wires together)
I took out the starter switch, and measure the resistance between different pins.
There are 5:
5) (something I forgot).
When off, there are two pins connected (I forget which is which. I can update this when I got home).
When on, nothing is connected to each other.
When start, nothing is connected to each other.
This is where I suspect the starter switch causes problem.
I read somewhere that when on (running) certain starter switch acts that way. However, it can't be the same as start. Because if that is the case, then how does it know what is what.
Without taken it apart, or replacing it, is there away to test this?
I know for sure that if I know the pin out, I can just use wires to connect them and test it out.
The problem is I can't find document for this.
The battery doesn't lose charge, so it's not shorted when not turning on.
