Does anyone know what I can use for sending units that will work with original Jaeger gauges from an early 600? I need a sending unit (aka sensor) for water temperature, oil temperature and oil pressure. Does units from some other make or model work? I really don't want to modify the internals of the Jaeger gauges, but am also wondering if there is a resistance bridge that I can make that will adapt the signals?
There's a lot of Jaeger gauges out there so what do folks do?? Of all the Jaeger gauges I've seen on ebay, I've never even seen a single sending unit for sale.
Thanks,
Gil
