RE: CVA Electra ARC Ignition
Yep, it seems to handle ok. But for me electronic ignition on an ML is not something I would ever consider.
If I were to guess what some of the problems the ARC may have, it would start with moisture and it's effect on the electronic ignition module. Seems to me that would be the likely spot for issues.
A down side to this approach is, if there is an issue with the electronic module, your ML is useless until you get it fixed.
With flint, percussion and 209 ignitions being much more simple there is really a small instance that the ignition aspect will be the issue.
