Toro LT electrical problem:

[Buckshot 1]

Hello Fellows, I been out of the game for a while, some health issues, which have been corrected, and I am now back in it. Toro/Wheelhorse 15-44HXL, MN: 71192, SN: 3902382. Turn the key to start nothing happens, like no battery power. All the safety switches by-passed and they all have 12v's in and 12v's out. There is a safety relay Hella 12v,4rd,960 388-07 in the electrical wiring. Starter soleniod is a 4 post with a ground wire coming out of the safety relay to a small post of the soleniod. I have checked both the soleniod and the safety relay according to the Toro riding products demystfication guide and they both check good. As I have battery power to the battery side of the soleniod, I tried to jump the soleniod large post and get nothing. I am at my wits end on this tractor. Any ideas/suggestions on solving this problem will greatly appreciated. Thank you for your time.

Bad ground, stuck starter brushes - try jumping direct battery positive to starter terminal and see if she cranks at all if not, you got a problem with starter or ground from engine to battery.

I forgot to mention that in my post. Jumping starter from the battery, does crank the engine. Connecting my test light to the postive side of battery and checking engine/frame ground also soleniod ground is good. Something that think is odd, that when using above the procedure, I get no ground on the starter switch case. As the dash is plastic, you would think there would some kind of ground for the starter switch?

The ignition switch housing doesn't need grounding.

Have you tried jumping across both of the large terminals on the solenoid? Also is the solenoid a 3 terminal or 4 terminal? If 4 terminal one of the small terminal is grounded thru a safety switch and other has 12v when the ignition is in start position.

If you have a link to the electrical diagram that you post that will make troubleshooting easier.

removing wires from both small leads on solenoid and running a wire from one directly to battery + and the other directly to battery - should pretty much test solenoid. Should click and should crank.

Download an owners manual here: https://lookup3.toro.com/request/request.cfm It will have an wiring diagram in it.
Yer prolly gonna end up with a bad ground. Check the ground cable where it attaches to the frame. Pull the battery bucket and you'll see it. Inspect the lugs, and clean em.

Glad to hear you're okay Don. Asked the guys at C&C if they had seen ya, but that was over a month ago.

Nothing happens when jumping large terminals. 4 post soleniodand one small terminal is grounded. According to the wiring diagram everything goes thru the safety relay. I am not computer savy enough to post the wiring diagram.

: Tried that and it still will not crank. Pulled the soleniod and while testing on the bench, it will click.

Put my test light on the battery plus lug and every where I touch on the engine/frame I have good ground. So I fiqured that the ground to the frame must be okay.
