OhioGuy89 4 #1 Posted January 5, 2015 Hi folks, me again. So I've managed to piece together my 520-H after tearing it apart, and after a night of charging the battery, I went to,turn the key and have no electrical power whatsoever, being that it has Sat for a couple months, do you think that the battery,,even though just two years old, could be completely dead? Also, I have a pic of the voltage regulator, and I am having trouble getting a clip on. Any suggestions? Matt Share this post Link to post Share on other sites
snowhound 103 #2 Posted January 5, 2015 I've never worked on a 520 but on the models I have worked on an open safety switch would make it seem like there was a dead battery when you turn the key, that is nothing happens.. Ed Share this post Link to post Share on other sites
OhioGuy89 4 #3 Posted January 5, 2015 Hmm. Any idea where such a safety switch could be ? Share this post Link to post Share on other sites
km3h 543 #4 Posted January 5, 2015 When you say you have no power, what do you mean? When turning the key do any of the gages move. Do the lights work? 1 Share this post Link to post Share on other sites
can whlvr 991 #5 Posted January 5, 2015 hook up battery cables off your car or truck,then you will know if its a wiring issue or battery,then you can start lookin for loose wires,fuses,and especially connectors,they get loose and corrode Share this post Link to post Share on other sites
Shuboxlover 474 #6 Posted January 6, 2015 On 520's there are PTO safety switches and a neutral safety switch. I think those are the only ones that would prevent it from starting. There is also a seat switch, but that won't stop it from running if the PTO switch is not active. Things to check....Battery (as mentioned)........FUSES!!!!........Ignition switch.......safety switches........One thing you can try quick to see if your battery is dead, put a pair of pliers across two big terminals on the starter, you're taking everything else out of the equation. If the starter engages when you do that, the battery is good. Turn the key to the on position and see if it will start. That might help narrow things down.

OhioGuy89 4 #7 Posted January 6, 2015 I'll check those things out. When I mean no power, what I mean is when I turn the key, the gauges don't even turn on before I turn the key to start the tractor. No gauges, no lights. etc. Share this post Link to post Share on other sites
boovuc 1,090 #8 Posted January 6, 2015 Make sure your fuses are all OK. There should three fuses in the fuse block. The 15 amp fuse is for the gauges/lights. 25 amp is the main fuse. The 30 amp is the starter circuit. If your fuses are all OK, you have to make sure your safety switches are working or if you must, by-pass them. You must be sitting in the seat, you CANNOT have the PTO engaged and you must have the transmission in neutral and you should have the parking brake engaged or your foot depressing the brake pedal. Double check your connections since you had it apart. Voltage regulator. Solenoid, the connectors from the motor to the electrical system, a good ground, etc. Share this post Link to post Share on other sites
rmaynard 14,864 #9 Posted January 6, 2015 First thing you need to do is go to Walmart or similar store and buy a multimeter or at least a test light. 2 Share this post Link to post Share on other sites
OhioGuy89 4 #10 Posted January 7, 2015 Found my multimeter. Checked the fuses and battery. Fuses checked out fine. Battery shows 13.83 V Share this post Link to post Share on other sites
wmsue 4 #11 Posted January 7, 2015 Are you sure the fused wire that connects to the ign switch is connected to the HOT side of the starter solenoid? I spent a lot of time finding that mistake I made one time. Good Luck Bill Share this post Link to post Share on other sites
OhioGuy89 4 #12 Posted January 7, 2015 I just figured it out! It was the stupid motion lever safety switch. The parking brake wasn't on, so the switch wasn't activated. Derp. Share this post Link to post Share on other sites

Because I have sat on my tractor(s) for a good long while wondering why it wouldn't start! Glad that is all that was wrong! Share this post Link to post Share on other sites
bmsgaffer 2,043 #15 Posted January 8, 2015 Haha, yep! I've had a "non-running" tractor that I was diagnosing for two days 'cause I left the PTO engaged. There was no deck attached, so I just didnt think about it. Share this post Link to post Share on other sites
OhioGuy89 4 #16 Posted January 11, 2015 Got one more question for you guys, I went and got a galvanized bolt to conect my positive terminal because I lost the original one. When I go to turn the key to start the igntion, the positive terminal sends up sparks. Any reason why this could be? Share this post Link to post Share on other sites
N3PUY 1,031 #17 Posted January 11, 2015 (edited) Dirty, corroded, oxidized connection. Take the terminal off and shine-up both the wire terminal and the battery terminal. Reassemble and coat with battery term protector or grease. The spark is the electricity jumping across the dirt. Edited January 11, 2015 by N3PUY Share this post Link to post Share on other sites
