Kid with a wheelhorse 0 #1 Posted 16 hours ago I have a wheel horse commando 809 that has the weirdest wiring that I have seen that is most likely modified (I got this tractor from a neighbor) and I need help finding a new one or figuring out how to re build it Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,731 #2 Posted 15 hours ago Welcome to Red Square. The wiring is fairly simple and you should be able to determine the problems with a wiring diagram. We are here to help so post your thoughts and questions. 1 Share this post Link to post Share on other sites
ri702bill 10,025 #3 Posted 7 hours ago Welcome! 8 hours ago, Kid with a wheelhorse said: or figuring out how to re build it So... how extensive do you need to go with this?? Engine smokes on startup or all the time? Axle seal weeping or the Unidrive not shifting properly?? The extent of the issues determines whether your tractor is either the parts donor or recipient of a rebuild.... All it takes is time and money. Wiring - perhaps @ebinmaine can give some insight as to wire gauge sizes and quality connector terminals. He has done a few... Watch the classifieds section here for possible additional tractors for sale in your area - Horses are herd beings, ya can't have one without a companion.... 1 Share this post Link to post Share on other sites

Yessir. Years ago I got into the habit of using a seven wire trailer harness to build my own tractor harnesses. Most of the wires are 14 gauge. I tend to use 12 gauge for the main power feed. I also make my own battery cables. Gauge varies a little on those. 1 Share this post Link to post Share on other sites
ri702bill 10,025 #6 Posted 6 hours ago Another suggestion on wiring - Your WH did not come with an inline fuse to protect the starting and charging systems. DO consider adding one - a blade style in a closed weatherproof holder- especially if you are going to keep the OE ammeter. When those fail, it can result in a direct short to ground, and then things "heat up". 2 Share this post Link to post Share on other sites
rmaynard 16,574 #7 Posted 5 hours ago The wiring on a Commando 800 should be pretty simple. (See the manuals that gwest_ca attached). Only the battery and starter require heavy wire. Everything else is 14 or 16 gauge. You must make sure that all ground connections are good. Make sure that you have the correct ignition switch, and the rest is pretty much 'connect the dots'. Five-pin ignition pigtails are available from Amazon. Good luck. Welcome to RedSquare, and remember that we are all here to help. 1 Share this post Link to post Share on other sites
953 nut 62,131 #8 Posted 2 hours ago Before making assumptions on the Commando's wiring needs there are a couple of things we need to know. Is the engine the 8 HP Kohler the tractor left the factory with (or one like it)? Is the engine ignition system a magneto or battery powered system? Is there a number on the present ignition switch? Is the clutch safety switch presently in place and being used? We have some rather generic wiring on this site that could be customized to fit your needs once we know what we are working with. Below is the factory wiring drawing. 1 Share this post Link to post Share on other sites
rmaynard 16,574 #9 Posted 59 minutes ago A picture of the tractor and engine would be nice. Otherwise we are spitting into the wind. The Commando 800 was produced in 1972 and 1973. Both years it had a K181S-30461D engine. That engine has a regular starter with a Bendix gear engaging the flywheel. It should have a separate solenoid. The tractor had a battery ignition meaning that there is stator under the flywheel with two usually white wires coming out that terminated at the rectifier/regulator. At this point I will stop until we have some more data, PICTURES...please. 1 Share this post Link to post Share on other sites
