/ X$ N- A& V1 H6 }1 pTwo cutler –hammer advantage starters are doing the same thing:
; S# `. ?/ P* E+ p J 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.
( L" i& }# m, g+ HIt is a cycle.8 e4 t' c% u; |! x; e

We isolate the network control and use the local start and stop only, the problem remains.7 F1 z, h" r/ f) \7 k% f
Swap one of the defective buckets with a good one, the new bucket works fine.3 T1 y& W# ^' Y2 Q9 B! c; Z
The problem should be inside the bucket. U/ ^4 X6 m; M

When the problem happened, we observed that the contactor has a pulling action but will not seal.) t# ?; H! Y; K/ @! ^* _ s
Use a terminating screw divers to push in the contactor, it will not seal either.
0 i/ Q" _6 ]0 G7 R; c' TConfirm 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.

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. " G& H# }. V8 Y
