Ts100 PTO nightmare, help

[Shadow_storm56]

We have a fairly old TS100, for the last few years the pto would never stay on or wouldn't start or randomly be just fine. Other tractors it's easy to bypass and just send power to the solenoid... this one's overcomplicated and crazy so you can't. Everything in that system has gone bad. The controller relay, the switch.... the solenoid to engage it still works but it needs multiple things for that to even work.

I sent some photos, I tested many things underneath and couldn't get it. Is there any combination of connections or anywhere I can send power in this mess of like 12.... spade connections just to turn on the pto with a simple switch so I don't have to spend more than the tractors value on little sensors and things to make it work normally again.

That LOOKS like a “pair” of common automotive 40A relays simply placed adjacent.

Potentially, I just need to know which terminals to cross to directly send power to the pto solenoid

Without a wiring schematic, I personally don’t want to answer that specific question.

However, .. in Most-Cases… I personally prefer to keep things (operationally) as OEM as possible…. using the least amount of my money as possible.

If it were My Machine… I’d first examine the wiring schematic…Then, if it really IS simply two cheap relays adjacent to each other….. I’d either install the cheap relays to see if that’d work… OR…I’d spring for the OEM replacement-relay.

(It would Not be my First repair-attempt to alter or by-pass the safety and function of the OEM design. )

I respect the owner’s (your) privilege of altering or modifying the tractor as seen-fit, however.

Let’s see what others might suggest.

My Snowmobile Club had one years ago, got rid of it. It aways had elec. issues British wiring and engineering, just bad. We never ran the PTO though.

What you have appears to be mostly standard five pin relays. The two pins one on each side would be numbered pins 85 and 86. Those are the power and ground circuit to energize the relay's internal coil. The other three pins in the center. The vertical one (on the bottom) is pin 30 which is battery power, whether switched or unswitched, fused or not. The two above it are pins 87 and/or 87A. Typically 87 is the load and 87A is connected to pin 30 until the relay is energized, then pin 30 is connected to 87.

That said, if pin 30 is "hot" then jumping that to pin 87 should power whatever the relay is designed to operate.

This is the pin that has battery power

The socket you pictured SHOULD be the switched control circuit as I see it. I would examine the relay you removed from that socket for any numbered pins. The one marked 87 would be the circuit to the PTO solenoid. Applying 12 volts to that circuit SHOULD energize the PTO. Considering the number of issues you have, who knows?
