re: Oil Pressure Sensor (attention:Ed Prytherch)

Ed, for what it's worth...........
A few years ago I had the oil pressure sender for my '74 Spider tested by
an instrument technician.
He tested it using air pressure in 10 pound increments from 0 through 80
psig recording the current and the resistance.
The readings were as follows:
 
PSIG		mA		ohms	
0		35.6		367
10		38		340
20		42		320
30		45		287
40		48		246
50		55		206
60		66		193
70		74		176
80		85		165

>I have 5 sensors. The zero pressure resistance is as follows:

>70 spider - 240 ohms
>73 GTV   - 290 ohms

>spare 2  - 325 ohms
