% I  J. n- p7 d* F1 X9 wTwo  cutler –hammer advantage  starters are  doing the same thing:

It is a cycle.

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.4 x9 B; \* X  j; x9 f. ?
It is getting better  this time, we have 7-8 times of running before it quit working. 3 N& u1 n; _1 \3 i; e( k9 D0 F% B

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

Do you guys have any input on this issue?

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., Q8 L/ e5 a2 R4 T# {" X
Since your cutler -hammer works couple times,  I guess 侠客行 is right, or the sealing connection is just worn out.
