stevasaurus 22,229 #2 Posted September 8, 2019 I know nothing about 520's, but what you are talking about can be a bad coil, bad condenser and possibly a fuel blockage issue. Share this post Link to post Share on other sites
ol550 825 #3 Posted September 8, 2019 Do a search on the 9 pin connector and check the fuse holder for damage. 2 Share this post Link to post Share on other sites

953 nut 51,536 #5 Posted September 8, 2019 Fuse holders are located near the battery and tend to become corroded and lossen up. 2 Share this post Link to post Share on other sites
Ed Kennell 35,616 #6 Posted September 8, 2019 Are you saying it dies while running and the starter will not turn it over when you try to restart. If this is the case, the problem must be common to the starting and ignition circuits. Look closely at the PTO and seat safety switches. Sometimes simply unplugging the connectors several times will clean the lugs and restore good contact. Share this post Link to post Share on other sites
roadapples 6,981 #7 Posted September 9, 2019 Sounds like mine. It was the fuse holder.... 1 Share this post Link to post Share on other sites

No it starts and runs for a minute and then all power is out like you turned off the key and has no power for a few minutes and then it all comes back on Share this post Link to post Share on other sites
slider1_us 3 #9 Posted September 9, 2019 I changed all relays and still does it Share this post Link to post Share on other sites
slider1_us 3 #10 Posted September 10, 2019 so I changed all the relays and fuses still runs for a minute then all the power dies I wait a minute and all the power comes back Share this post Link to post Share on other sites
Ed Kennell 35,616 #11 Posted September 10, 2019 (edited) Have you unplugged and reconnected all the connecters? 9 pin molex seat switch both PTO switches ignition switch Look for broken or chaffed wires on the safety circuit. Look for any discolored spots on any wires that would indicate overheating. Edited September 10, 2019 by Ed Kennell 1 1 Share this post Link to post Share on other sites
lynnmor 6,762 #12 Posted September 10, 2019 While a number of connections can cause your problem, I would make the 9 pin connector the first priority. 1 Share this post Link to post Share on other sites
