For those of you that have older AIMs (like an XG Log)
Had my dash go intermittent and it waited to show up right after I unloaded friday afternoon. Two hours of troubleshooting the wiring and I finally removed he dash and the data box.
You can remove the top cover of the data box and the front panel. They are a little hard to pry apart because they are well gasketed. The main circuit board is held in with 4 screws. Under the board is a header connector that gets loose.
i re-seated mine and it was fine for 4 sessions and then went wonky again in the flag race, requiring a reset every lap. So now I'll have to do this again - and this time I'll glue the connector down.
