Not Reaching 240 ohms
Good Afternoon,
Both of my new from the box, never installed, S-W 385 senders read from 32 ohms at one extreme of arm movement to 195 ohms at about 3/4 of the movement of the arm. Then, both show an open circuit- i.e. 1 on the ohmmeter- for the remaining 1/4 of their travel. I'd say the arm is losing contact with the wiper at that point although I can't see it.
Can I reasonably diassemble the sender? If so and if I'm right about the arm and wiper losing contact, any idea about how to adjust them? Would I be better off simply buying two new senders and hoping for the best?
Thanks.
John
