Any input on Cutler-Hammer Starter?

Two  cutler –hammer advantage  starters are  doing the same thing:

We isolate the network control and use the local start and stop only, the problem remains.

The problem should be inside the bucket.

Use a terminating screw divers to push in the contactor, it will not seal either.

The next thing we can think of  is the coil, we took the coil out to have a close look.
They  have a fork to pinch inside the two leads to make connection, it is not a good design at all. We soldered  the connection and tried again.

The coil should be the problem, we ordered two of them. But it will take 5-6 weeks for us to get them.

有时候主接触点太脏，也会造成启动器无法正常工作

Don't know cutler –hammer advantage  starters very well, but had been worked on AB switch gears for a little while, which has two different coils, one to pull the vacum bottles up which employs larger current, another one uses less current to hold the connection---if the second coil fails, it won't be able to seal the connection.

也想到这一点，不过这是新装的设备。
