Two cutler –hammer advantage starters are doing the same thing:

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.

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.! g9 x1 H* u' V8 ^( `
