    Blue Wire

    Thanks for the help.

    Blue Wire

    Thanks for the link to the demyistification guide. Looking at the diagram I see that I have started at the beginning of the circuit and worked my way up to checking relays. I see the loom of wires going down under the dash sort of, to something up between the frame rails. Are those the relays ? How do I check them for good or bad?

    Blue Wire

    I replaced the pto switch, neutral switch and found where the seat switch has been by-passed. Also changed the ignition switch. These things were done trying to get the tractor to start with the key. Turn the key and nothing. This led me to check the ground to the starter. Should the blue wire in the female side of the 9 pin connector check good to ground with a meter? Mine doesn't. I can jumper the connections on the starter and start the tractor. The blue wire from the male side of the 9 pin connector to the starter checks good - no break in the wire.
  6. Visually inspected the 9 pin plug - both sides look very clean. No discoloration on any wires. Cleaned both ends of the ground cable from the battery to the tractor frame. Cleaned the positive battery cable at the battery. No change. I bought new pto and neutral switches but haven't had time to change them yet. I drive a semi and don't have much time on weekends to get much done. Hopefully next weekend I'll be able to change these switches. The shop that used to sell these tractors told me that the later years had the seat switch inside the seat. This tractor doesn't have a button switch under the seat like my 1988 does and therefore I had assumed that the switch had been removed and bypassed. I'l need to check to see if this tractor has a switch in the seat. That may be where the problem lies.
  7. I just read about the neutral safety switch. I'm going to locate that and see if it's broken etc. I'll probably want to trying to test that switch and I imagine the procedure would be the same as what I would do for the PTO switch. Looking forward to your responses on how to jumper these switches. Thank you in advance.
  8. Tractor ran fine last weekend. parked it in the garage last Sunday. Installed a new voltage regulator yesterday. Went to start the tractor to test new regulator output - Lights on the dash light up with the key in the on position, turn the key the rest of the way to start - lights go out and nothing happens. Seems to me I had those same thing occur when the PTO switch was out of adjustment. I messed with the switch (without removing it) - nothing. Is there a way to jumper that switch to see if that's the problem?

    Regulator test

    Used a multimeter on DCV to the battery with the original regulator still in the tractor. When running at about 1500 rpm the reading was 15.2 volts. Switched regulators to a spare from a 1988 and the same test showed 14.3. I think this regulator needs to be replaced. Ordered a replacement today.

    Regulator test

    I need to test the voltage regulator on my 1992 520H. I was told by a wheel horse mechanic that on these older Wheel Horse tractors, the regulator can go bad and charge too much power, eventually ruining the battery as well as other electrical components over time. I bought this tractor a month ago and it had a new battery in it. Per the mechanic that's a sign that something may be wrong with the regulator. Also the mechanic said, when the regulator malfunctions and over charges the system, several electrical components can be destroyed, one at a time if the problem is not corrected. No lights work on the tractor and the tach sits just under 4K at all RPMs. I just had to change the ignition module or "trigger". How do I test the power being sent through / out of the regulator?

    1992 520H Wiring

    Thanks everybody. Since I was on here last I did figure out how to download 7 manuals from the toro website. I may have everything I need as far as manuals for now. BTW - I fixed the no spark problem I had which was another reason to download the manuals. It was the Ignition module or "trigger" as I've heard them called. Not a fun, job but it's done.

    1992 520H Wiring

    I recently purchased a second 520H. It's a 1192, my other is a 1988. Developed a tranny problem on the 1988 and needed to get back to snowblowing ASAP here in Michigan. The 1992 I bought doesn't have a safety switch under the seat and the lights don't work. I can see two wires clipped under the hood, one green and one black. I didn't know if the wiring on the 88 and the 92 were the same, so before digging in and possibly making things worse I was trying to find a wiring diagram for the 92. Not had any luck finding a diagram so far in my internet searches. I see them for the 1988, and in fact there are two wiring diagrams in the owners manual that came with the 1988. Does anyone know if the wiring on these two machines are identical? Anyone know where I can get a wiring diagram for the 1192?
  13. The 1992 520H needs a new muffler. I've been searching on the internet to find a replacement with not much luck. Any suggestions?
