Hello. Read some post. Trying to bypass the water sensor by the relays. The oil sensor wire is good to relay and have grounded it out for now. Would any one have a wiring diagram for the relays?
Water sensor is on upper radiator hose. Why not ground that if you're going to bypass it.
Stoopid site wouldn't let me post other day. The engine protection system can be disabled by connected two terminals in the rear door harness. They are a male and a female bullet connector, tied in with blue electrical tape, on the door wiring harness, just outboard of the door pivot area. Placed together, the oil pressure, coolant temperature, and, if equipped, coolant level sensors will be bypassed. Since that's essentially a TL130, and nearly identical, wiring wise, to a TL150, I'd first suspect failed (cold) solder joints in one or both of the relays in your picture that start with BE31. They are around $70 new, are the only ones that give issues in that panel, and, can be disassembled, inspected, and in most case resoldered. Read through this thread, especially page 3 and the pictures. HeavyEquipmentForums
