eibbed 63 #26 Posted June 12, 2022 Gentlemen, We have had this mower since 2003 and really have not had many issues (knock on wood) with it except for the PTO family. David always kept it maintenanced and I do try to do the same. Doc, you mentioned the switch under the seat. I do not have this switch. The seat is wired for the safety switch, but that is all. I did order a Toro OEM PTO switch and I should have it by the end of this week. I will let you know the results. In the mean time I will figure out how to use the multimeter and check the wiring. I need to learn how to do this anyway. Thank you everyone for your assistance. I really appreciate it. Debbie 1 Share this post Link to post Share on other sites

But, these numbers may, or may not, appear on the switch itself. You MIGHT find them on the connector that plugs onto the switch with a magnifier and a bright light. 2 hours ago, Snoopy11 said: what pin does +power go into on the switch... pin 1 / pink? Correct. The white wire on pin 2 goes to the PTO light on the dash. My money is on a loose connection somewhere. During the course of changing the belt something was dislodged, loosened, bumped, whatever... if something works before, and not after, it's always best to carefully retrace ones steps and look everywhere that they touched. "99% of troubleshooting is visual" You can usually find the problem by careful observation using nothing but your eyes. @eibbed Edited June 12, 2022 by Jeff-C175 2 1 Share this post Link to post Share on other sites
Jeff-C175 7,199 #28 Posted June 12, 2022 45 minutes ago, eibbed said: figure out how to use the multimeter Basically... You have a red and a black lead. The BLACK goes on GROUND (the negative terminal of the battery is a good place.) The RED lead will be what you 'probe' with. Set the meter for " DC VOLTS " or maybe " DCV " (if you post a picture of the meter it will help us help you with the exact settings) With the meter set to DC Volts, and the black lead on ground, measure for 12 V on the brown wire when the PTO is engaged. If your test leads have 'pin probes' on them, you should be able to stick it into the back side of the PTO switch connector without having to unplug the connector from the switch. (this is called 'back probing') 1 1 Share this post Link to post Share on other sites

Kinda dumb, in my opinion... 1 hour ago, Jeff-C175 said: My money is on a loose connection somewhere.

Precisely. Could be from merely changing the belt, or when the belt grenaded... (usually they hit everything under the mower including wiring...) 1 hour ago, Jeff-C175 said: 99% of troubleshooting is visual Don't forget that 1% though... Just because something LOOKS sound, doesn't always mean that it is. I even like to take connectors off, and give the wires on them a little tug just to make sure.

eibbed 63 #31 Posted June 13, 2022 Now that I have somewhat of an idea to use the multimeter, I will check the wiring tomorrow. I have a Cen-Tech 7 function digital multimeter and it does have the pin probes. It does show DCV with numbers 200m 2000m 20 200 1000 I'm not sure which number to set it on. I checked the connection to the pto clutch and it was fine and the other connections to the mower. But I will recheck everything tomorrow. Thank you again for your feedback. 1 Share this post Link to post Share on other sites
Jeff-C175 7,199 #32 Posted June 13, 2022 16 minutes ago, eibbed said: I'm not sure which number to set it on. Set it on " 20 ". That is the 'range' of the readings. By setting it to 20 you can measure between 0 and 20 Volts. Good for measuring 12 Volts. The ones that say "m" are MILLIvolts. VERY small voltages. There are 1000 millivolts to a volt. The 2000m scale would allow you to measure between 0 and 2000 millivolts which is actually 2 Volts. Useful for checking flashlight batteries and such. It's unlikely that you would ever have any use for the other ranges at all. 1 Share this post Link to post Share on other sites
eibbed 63 #33 Posted June 14, 2022 Jeff-C175 Thank you again for the information. Today is the second day of 100+ degrees. Expected high temps for a while. We only had a week or so of Spring and it looks like Summer is here I am not a fan of the heat or humidity so it may be a bit before I get out in the garage. I will keep you posted what I find out.

gwest_ca-(File Mod) 11,036 #36 Posted June 15, 2022 Do not know if this is for the 5xi switch part number 95-7489. It is in one of the Demystification Guides but not identified. 1 1 Share this post Link to post Share on other sites
eibbed 63 #37 Posted June 18, 2022 Gentlemen, I have awesome news. My 520xi is up and running!! I finally had a day where it didn't feel like 110 outside. We had a cool front move in for today and tomorrow. 85 degrees. I'll take it!! I received the new PTO switch. Plugged it in and it did not work. I rechecked all the connections to the PTO clutch and VOILA, I found one connection I apparently overlooked. Snapped it back together and it was a Thank You Jesus moment!! The new PTO switch does works so I will put it aside in case I ever need one. I was able to cut my lawn today and it was ready. Hooray!! I have a wonderful neighbor who is seventy and has cancer and he helped me. (He loves to cut grass and he has a John Deere. But I don't hold this against him. LOL!!) I am truly blessed to have wonderful neighbors. And I feel I have found wonderful friendships on this forum. Thank you to everyone for all of your advise and schematic diagrams. I appreciate each and everyone of you. And I feel David is thanking you too! HAPPY FATHERS DAY to all of you!! Debbie 2 Share this post Link to post Share on other sites

And just to reiterate my previous advice: [broken record mode ON] 99% of troubleshooting is visual! [broken record mode OFF] Glad it all worked out for you! We too are blessed that you found us! 2 Share this post Link to post Share on other sites
