I have a 582 with a water probe that has 2 wires extending out an epoxied hole in the probe and appears to be faulty now as it some times works, the needle sought of comes up then drops off, the last probe I had did this and I thought it was the guage so bought a new guage and later found out that it was the probe. I see MGL have a water probe with a one wire attachment to it and no epoxy in the centre, can I use this probe instead of the 2 wire epoxy one as it is giving me grief. Cheers.
