yay 100% sensor health that's the 1st time ive seen that lol

and for my next trick i will use the alternator exciter wire to trigger the relay for the booster pump and the charge cooler pump so they only run when the engine is running and not just when the ignition is on
probing the wire with the engine running shows 14v

and with the engine off but ignition on 0v 🙂

time to drain the water again :confused:
