2007 update: The new 24V power supply fixed the problem, but there has been other occasional problems with the same machine. I also had to replace the main lube pump due to electrical corrosion caused by coolant getting in to the pump electronic controls. The next two replacements quickly failed, the pumps would go crazy and just keep pumping too much oil at irregular and reduced intervals, regardless of the pot setting. So I had to replace the uinit with a Bijur mechanical timer unit (model TMD-1; 26350-1) that is better sealed against outside contamination. |
