[alfa] 105/115 oil pressure gauge Veglia v. Jaeger

["Dean W. Cains" <dwc@xxxxxx>]

Hi Group:

I've got a '74 Spider, and I've just installed a complete set of gauges 
from a 1600 Duetto ('67?).  I prefer the Duetto gauges because they have 
the Italian units and legends, and as a bonus, the set I found is in 
beautiful condition.

Everything works and looks great, except the Veglia oil pressure 
gauge.  I'm guessing the Veglia gauge is OK, but only because it has 
resistance (~51.8 ohms), rather than an open circuit or dead short.  It 
doesn't react even slightly to the oil pressure sender when the engine is 
running.  The original Jaeger gauge has a resistance of ~134.8 ohms across 
its terminals, and works fine.

So, the questions are; is there a way to test the gauge, and/or is a 
different sender required?  Or, if the gauge is bad, who can repair a Veglia?

I just spoke to Steven at Centerline, and he seems to think the later-style 
('71>)sender should be compatible with the older gauge, but I was a bit 
confused by his logic in reaching that conclusion.  Anyone done this and 
know for certain?  Or, anyone have a 1600 Duetto and tried using the later 
sender with a Veglia pressure gauge?  I'd hate to drive the '74 without a 
pressure gauge, even though I haven't ever seen the gauge in my '87 Spider, 
thanks to the single pod dash design which places the pressure gauge 
squarely behind the top of the steering wheel.  Thanks in advance.

Regards,

Dean
