# ~" e) r9 t! r  b( e8 z/ ^Two  cutler –hammer advantage  starters are  doing the same thing:
After start 2-3 times, they will quit working, if you toggle the  start and stop buttons on DCS screen  , you will get another 2-3 running before they quit working again.
It is a cycle.

# t: }! M' `$ w# F9 qSwap one of the defective buckets with a good one, the new bucket works fine.
The problem should be inside the bucket.

When the problem happened, we observed that  the contactor has a pulling action but will not seal.
Use a terminating screw divers to push in the contactor, it will not seal either.
& F* l0 A5 M4 iConfirm with TECH support this should be a problem with the control circuit board inside the advantage starter, we  bought two new control circuit boards and replaced the old ones, the problem is still the same.

1 n- H3 G8 f3 E" W9 cThe 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.
: U. T5 g+ S8 ~4 H) J( Z It is getting better  this time, we have 7-8 times of running before it quit working.

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。
检查过触点没问题。
