Master contactor question
My homebuilt's master contactor is going bad. Sometimes when I turn it
on it doesn't make connection. It's got 1700 hours on it, so I'd just as soon replace it. But the way the builder wired it, he's has positive power from the battery going through the master switch to the small terminal on the contactor. (cole-Hersey type) But the master contactors, such as Spruce sells, are set up to actuate with ground power going to the small terminal. They also have plastic around their mounting feet so their case doesn't make ground. A starter contactor would work perfectly with the way the plane is wired. I just wonder, are starter contactors made to withstand continous use, like a master contactor does? And how can one tell the difference in the two, they look identical? And if not, can the master/continuous duty type be made to work with postitive power to the small terminal? |
