I own a 3 year old Ariens lawn tractor model # 93606000/A175G42. It has a 17.5 Hp briggs and Stratton. My problem is rats have chewed the wiring between the engine and lights and I cannot figure out what goes to what. I have seen the wiring schematic but it does not give me good wire colors. The 4 wires I have a problem is the two that go to bottom of carb(gray and black) and the 2 that go up to ignition( red and black). I cannot figure out where these connect to. Thanks. Joe B.

Ahhhh...the dreaded mice!  From my experience with mice, they will chew the insulation off down to the bare copper and leave the copper wire.  This has always been done in spots in my experience.  I have seen them chew wires in half also.  Did the mice leave any insulation remains you can trace/match up?  That would be the easiest way.  If there is no insulation to identify the wires, you'll have to tear into your wiring harness and trace wires.  It's not fun, but it works.

 

I have also found that some colors of insulation apparently taste better than others...to the mice anyways!  :D

 

Good luck with your fix!

Thanks Billy the problem seems to be that the wires going through a removable connector are not same color ? If anyone had this model with a pic of right side engine wires that would be great. Joe B.

Like BillyM said.  Take a SHARP pointed knife and start cutting the loom open with the point up.  Go as far as you have to to get to the insulation on each wire.  Lot of times it is just as easy to remove all the loom or harness.  When your back going again you can hold the wires together with small zip ties or plastic split tubing.  Original type is also available.  Get mine from All Electronics.  Good luck and take your time.  You will get it figured out.

Not uncommon for the color to change when going through a connector.  Work with one wire at a time, from one end to the other.  Repair/replace as you go.

20161012_135921.jpg I have 17 hp  engine I can take picture of the connector as soon as I finish lunch running a bit late today.

this is an older craftsman mower. I think Ariens are made by the same company

Welcome to GTtalk!
Not really familiar with the newer models. I assume the two to the carb are for a fuel shutoff. Which should be feeding off the ignition switch.

The gray wire should be the fuel solenoid. the solenoid has 2 wires at the solenoid one is grounded to engine. the solenoid ground does not go through the connector. The black wire is the engine kill wire and the other two wires come from the alternator. The alternator wire with the diode is the batter dc charge wire and the other wire is for lights( AC voltage). This is a Briggs engine without voltage regulator.

 

after looking at the wiring diagram for your model

fuel solenoid is a blue wire

ignition unit kill wire has black wire with white tracer

 

hope this helps and Welcome to GTT

Thanks to all of you got it running !!  Jim thanks a whole lot. Once I removed the fan shroud I realized that what I thought was a gray and black coming from the fuel solenoid was actually the fuel solenoid and the kill switch. I thought I had 2 wires coming from fuel but as Jim said one was grounding under the engine. Thanks All But while I am at it since I bought this tractor new the clutch is very stiff in other words if I do not release slow or at slow throttle it will nearly pop a wheely. Gets a little better after it runs but still stiff. It is a gear drive. Any ideas.

the clutch petal release just applies tension to the drive belt. As belt tension is applied it turns the peerless transmission. I cant help you if there is any adjustment. I don't know. Glad you got wiring squared away.

The linkages could be out of adjustment or there could be something flukey with the drive pulley that causes it to grab quickly.
