Re: 1988 JD 180 - electrical
Hah!! That's what I used to say when one of my pals would be working on their "advanced years gear."<G
Something isn't tossing that relay...the PTO triggering with the ignition on points in the direction of the pto safety. It's not a huge ordeal to pull off the body in order to inspect it and wiring. I may reach up and trace a few leads for any insulation peeled off as it's in tight quarters to the belt and transmission sheave. In fact it was a drive belt replacement ordeal that alerted me to the location and how easy it was to pull the connector apart while I was trying to get the belt into the transmission pulley.
The starting circuit was dead from that point...and by reaching in, I was able to find the loose wire and ask myself...."self....what the heck is this?" I originally thought it was an "option" that was there for the 185 with the automatic trans. Bolting it all back together just to find that the starter circuit was kaput...I realized the loose wire was no longer optional. With the body on there's not enough clearance to re-install the connector...so, disassemble for the sake of one relatively short wire from the harness and the voltage became present at the solenoid. Having said that....what we should have done was take a paint brush and clear out all the build up of clippings and dust; hose it down with electrical cleaner and make sure it had a full connection again.
Throwing the body back on...without bolting it together this time, depressed the seat and turned the ignition and we were back in business. Or so I thought. Bolted back down and everything secured, climbed on with me and the crew holding a cold beverage and turned the ignition...dead at the starter again.
The clearance is so tight that when I cranked up, the belt found the wire close enough to snag it and drag it back off the relay. I reached underneath and found the same colored wire and broke the news to the guys and pretty much the entire side of the county. Babies started crying and women started to faint from the "words of disappointment."
Once more...off with the body and down on the transmission....got the compressor to blow the stuff off...completely which was the key. Shoving the connector back on while seated in the debris that I actually swept back under neath the male end of the relay caused the wire to be just in the wrong spot and a pretty sorry connection to boot. Lesson learned. Do it right the first time....which we did. I'll let you know the findings after I pull things apart and check the pto safety relay to see what may have happened in the interim.
I don't know if the pdf loaded for the JD180 elect.schematic...but this one will show you just how simple things were just 30 years ago.
It's not that I have an urge to tear things apart...but when they can use a little attention, I get as much ammo as I can before hand. My best example of this is my Hewlett Packard Design Jet 500...a large format printer for architectural drawings. I purchased it new in 2001 and every so often have to work with it to keep it going....my hands are a lot bigger than the little guys in Japan for servicing this critter. I learned to improvise and just like the John Deere service manual...when it says "remove bolt from spindle mandrel" it actually means....get your right angle grinder and cut off the bolt and nut. Ditto on the HP DJ 500....what they say to do wasn't meant for hands that go along with 280 lbs and 6'5" of me.
The challenges continue.<G
Thanks Brad! I'll be back in touch as soon as I can settle in to step the 180 through it's fix.
