Hi Jon
There is no fix for this issue other than disconnecting the battery from the ecu before charging. In your case, you could disconnect the battery cable from the ecu and then use the charging pigtail. This would assume that the battery connector on the ecu is accessible of course. Which charger are you using?

Last year there was a notice sent out to disconnect the ECU battery before charging, as some charges ruined the ECU.
Has there been a resolution or fix for this, or is there a list of chargers that can be used and not damage the ECU? In my new plane, the ECU battery is buried and it's going to be a pain having to unplug it, instead of using the charge pigtail, everytime I charge.
BRG,
