eric8 5 #1 Posted yesterday at 01:54 PM Hi folks. New member here and I've just acquired my first Wheel Horse ever; a 1993 520H. Does someone have any good reference photos showing the factory routing of the battery cables? Specifically, how they exit the battery "box" area? Would also like to see how the negative side cable is attached to the frame/engine. Lastly, my machine has a large rubber line on the right side of the engine that starts underneath the muffler area, runs down across the PTO pulleys, and dumps under the frame. I'm guessing some type of drain, but I can't tell what it's draining? Nor do I see it in any of the parts breakdowns. 1 Share this post Link to post Share on other sites
Handy Don 16,692 #2 Posted yesterday at 03:07 PM Welcome to the Forum! Just to help out, how about taking and posting a couple of pictures of what you’re looking at? Best are JPEG (HEIC, the default iPhone format, won’t work). 2 Share this post Link to post Share on other sites
eric8 5 #3 Posted yesterday at 03:26 PM No problem, I will get some photos of my battery cable routing as soon as I get home. As far as the unknown rubber hose, here is a pic of it circled in blue. On my tractor, it appears to be going to nothing on either end. 2 Share this post Link to post Share on other sites

It pulls the PTO clutch together to engage the mower deck. Real nice looking tractor !! Edited yesterday at 04:37 PM by Achto 4 Share this post Link to post Share on other sites
JimSraj 577 #5 Posted yesterday at 04:38 PM That’s not a rubber hose if I’m looking at what you are asking about. It’s part of the PTO clutch assembly. 4 Share this post Link to post Share on other sites

Well I feel like a fool now looking at that all this time thinking it's a hose! (p.s. that tractor in that photo isn't mine, it's just one I pulled off here) 2 Share this post Link to post Share on other sites

eric8 5 #9 Posted 19 hours ago Well as promised here are the photos of my battery cable routing. It just doesn’t look “factory” to me. 1. Unsure if the cables exiting the battery should bend back and go down by the sides of the battery as currently configured? Or go forward over that black cross brace, and then down between the engine and “firewall?” 2. Unsure if negative connection to engine/frame is factory correct? All other engine mount bolts are pointing down with the bolt head “up” except for left rear which has the nut on top, and the neg cable sandwiched between the bottom of the frame and bolt head . (3rd pic is of all the engine mount bolt configurations except for the upside down one containing the negative cable lug) Tried looking for some factory literature or brochures that would show a correct 1993 configuration of this stuff but coming up empty handed.

Or go forward over that black cross brace, and then down between the engine and “firewall?” I think that cable routing looks pretty good. Attaching a trickle charger and still being able to close the hood is nice. Also, WHEN that 9 pin connector starts acting up- the main battery cables won't be in your way. And grounding on an engine lug is actually a good idea. The 520 series tractors have more wiring than all of the rest of the classic models. There isn't a clean and neat version that I've seen. The absence of wire nuts, scotch locks, or electrical tape is a good thing. 5 Share this post Link to post Share on other sites
lynnmor 8,831 #11 Posted 4 hours ago My 91 has the bolt head and ground cable below the frame, my 96's and 97 have the nut, washer and cable above the engine ears. The change may have been made to have a direct connection to the engine. Where is your battery hold down, as you can see it would only take a serious bump to make sparks?

Thanks for the input on how your tractors are configured. Guess the bolt and ground strap orientation could have been a running production line change, or may have been however the line worker felt like hooking it up that day My battery hold down is another part I've discovered is missing, so that is on the to-do list for sure.
