I have a 2016 Takeuchi TL12 that has lost all continuous flow functions. No electrical power to detent, one way, or high flow buttons. The momentary aux buttons work fine. I can run a cutter by holding down the momentary button. But when I hit the detent button for continuous flow it doesn’t light up. Same for one way button and high flow button. I’ve checked all relays I could find and all fuses. I’m fearing it’s the ECU. Anyone have any other ideas before I haul it 6 hours to a dealer?
Most likely it's a bad wire due to corrosion. Get a schematic and check all the wiring and switches.
Thanks for the reply. I have downloaded the factory service manual and found all 3 get their power from the same controller but the lights in the switches get power from a different controller. I’ll find those two tonight and check wiring between then.
Hi, I have the same problem. Did you ever figure what the problem was?
Did anyone ever find an answer to this? having the same issue on a 2021 tl12r2
In my case it turned out that the switch was bad. I replaced and all worked fine.
THanks for replying! Which switch did you have to replace? I have an issue with hf, continuous fow detent and the one way switch.
I don't recall whether it was the continuous flow or high flow switch. They are easy to pull out and test with a meter. Also make sure the switch controlled by the lever that is engaged when you connect the hoses is working - I think that is also part of the continuous flow enabling circuit.
I know this is old, but you are correct. The first switch to check is the switch on the arm that gets engaged by the couplers.
