; y( f9 `7 s7 e2 S+ g/ FTwo cutler –hammer advantage starters are doing the same thing:

It is a cycle.) h$ \$ V+ ]+ K/ p8 l$ w
3 }1 G, H v% {) K/ n& \2 w$ ~We isolate the network control and use the local start and stop only, the problem remains.

The problem should be inside the bucket.

When the problem happened, we observed that the contactor has a pulling action but will not seal.
8 ^$ K' f8 N1 t" g- f* LUse a terminating screw divers to push in the contactor, it will not seal either.
$ E4 u1 i2 `8 [ [- ^ HConfirm 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.

The next thing we can think of is the coil, we took the coil out to have a close look.- l7 s' @2 t1 z
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.
7 Y' ]0 y) [6 r$ N: L 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.
