Reflow every joint on the board, and I used a 170 watt gun to speed things up.
The broken joints are usually obvious, but not always. Solder can separate and break around the pins of the component on the board and yet LOOK fine from the solder side. This is why so many have reported, "the RCM looked fine, but replacing it fixed the problem." Of course, it can also be pitted contacts on the Engine Control Relay - but the vast majority of the time, it is fractured solder around the pins of a relay or connector.
Don't make this harder than it is.
The joints were re-soldered and put back in. The circuit board was checked to make sure it is ok too and all joints was re-soldered.
The mechanic is now taking out the starter motor to have a look at this today and will see where we end up by tomorrow.
Thanks
