I've found a place to purchase the Man engine sensors at a savings should anyone be interested. Good service and about 1/2 the cost of here. Just be sure you get the correct match. They are a UK company. M&M Controls
Nicely done! Do you carry any spares and if so which ones? I've only had one go out in 3 seasons. Knock on wood.
I carry an extra coolant pressure sensor. 51.27451.0125 Under M&M Controls its there 060G1122 MBS3000 0-2.5 4-20ma if you use the same one and I think you do.
I don't carry any spare sensors, as with most of them you can still run the engines and it doesn't set them into limp home mode.
