Bow_Extreme 544 #1 Posted September 21, 2022 Well, slowly gaining on a full repair. This is the mess I took out. Will most likely be the last of it, I hope. 2 Share this post Link to post Share on other sites

I just don’t understand why people mess with original stuff like wiring. It’s one thing to replace a wire because it’s worn or frayed but to turn what once was neat and organized into a rats nest is beyond me. 4 1 Share this post Link to post Share on other sites

The ignition switch has been replaced with a 4 position automotive switch and ALL the wires were hacked off at the end. Uninsulated butt connectors everywhere. Just. Silly. The cost of all that garbage was likely twice that(+) of a correct plug n play switch. 4 Share this post Link to post Share on other sites

It seems most “farm repairs” are less than stellar and wait for us to fix ‘em.

Diagnosing decades-old electrical systems, especially if problems are intermittent, can be painful. Upgrading with new wire and connections is a no-brainer for me when I have the time to do it. 3 1 Share this post Link to post Share on other sites

ri702bill 8,319 #13 Posted September 21, 2022 And I only see one toasted connector!! As @peter lena would tell you, now is the time to add additional grounds and use the dielectric grease... 3 2 Share this post Link to post Share on other sites

As @peter lena would tell you, now is the time to add additional grounds and use the dielectric grease... Standard procedure. All connectors are cleaned, replaced if needed, and packed full of di-electric grease before reassembly. The engine harness connector is replaced with Deutsch DT & DTP connectors. The Deutsch connectors are the only not original items on the tractor. I’m trying to keep this one original as possible. 2 5 Share this post Link to post Share on other sites

peter lena 8,625 #16 Posted September 21, 2022 @Bow_Extreme https://www.mmnewman.com/product/nylon-heli-tube-spiral-wrap/ regularly use this type of wire protection , for any wire runs , also do not hesitate to REROUTE WIRING , avoid tight bends and chafing , WHY NOT ? also verify connection / function at every stage , do not build in a surprise. use the battery cable ground bolt point as your secure / verified ground start . DO NOT COUNT on original factory set ups , why ? too many connection spots that can can be rusty , cracked broken , experience talking there , make every stage solid . pete 2 3 Share this post Link to post Share on other sites
peter lena 8,625 #17 Posted September 21, 2022 @ri702bill regularly use those electrical bolt on lugs as a bolt / mount ground go to , there are so many opportunities for ground / electrical failure , its just looking right at you . use those alligator wire test leads for verify as you go set ups , if you have a bolt , to go to add a solid connection . my original wiring set ups were at best at mess , when I switch on now , its solidly instant . you know what I mean , pete 4 Share this post Link to post Share on other sites

Fortunately the sixties tractors I favor have no safety switches and wiring is easy peasy. A 520 now a different story. Everything is buried and quite difficult to get at. @dclarke knows he did a frame off 520 and rewired everything. He used Deutsch connectors for some circuits. Hats off to Bow for taking on a 520 rewire. BTW guy I have some 520 harnesses if it helps ya. 4 Share this post Link to post Share on other sites

Strangest thing is when I'm wiring the ones from the '70s the safety switches seem to relocate themselves somehow. Haven't been able to find them since. Similar syndrome to when you put six socks in the washing machine and only five come out. But around here there's only adults operating the tractors and only under the supervision of me or Trina on the very very rare occasion someone else gets on it. I did leave the pedal switch in place on my one Automatic and I also will leave the switches in place on the Wallyho backhoe tractor because I think those two are appropriate to leave them. 2 2 Share this post Link to post Share on other sites

Jim, I was lucky enough to find a N O S wiring harness for that 520 so it wasn’t too difficult to replace. Otherwise it’s a real pain. 3 1 Share this post Link to post Share on other sites

Also a great time to eliminate circuits you don't want and add those that you do. For example, on my last rebuild, a 312H I removed the seat and neutral switches because I mow hills that necessitate me sliding off the seat and have matt's foot control that self centers itself for neutral. I also added a fuel gauge so that wiring was added at the same time to keep things neat. All of my 520's (5 of them) have had the harnesses pulled and cleaned up as required. Never had an electrical issue since on any of my 8 wheel Horses. 1 3 Share this post Link to post Share on other sites

Might be mistaken EB but same tank across the 3 4 500s. Take a 520 tank with the sending unit and slide it under a 300 and add the gauge & appropriate wiring. 3 Share this post Link to post Share on other sites
