Two cutler –hammer advantage starters are doing the same thing:, t5 v3 s: ]% W+ }2 e9 [( |5 N* M, X

It is a cycle.

Use a terminating screw divers to push in the contactor, it will not seal either.: T; K7 C! |% ~: \# ]/ f
Confirm 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.: x' E2 Y) l3 F- _1 |$ G
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.
