Robert,

Yesterday I went out the run the engine on my new plane. It has the EQ-10 and I run dual A123's and the soft switch.

I found the Deans plugs have an intermittent connection. It was so bad the vibration from the engine could cause a total power shutdown of the system. When I wiggle the battery wires side to side the system loses power.

Could there be a problem with the plugs themselves? I thought about trying to bend the spring slightly to increase pressure between the contact plates but thought I would try here first.

I also tried spraying some contact cleaner on the plugs and that eliminated the problem, until the cleaner evaporated and then the problem returned.

Obviously I will not fly the plane in this condition. I am down anyhow waiting for a carb rebuild kit.

Is this a problem you have seen before with the Deans plugs? It almost seems the connection would be more stable if they were mounted to a short jumper, or even replaced altogether with EC3 plugs (which contact between the ID/OD of cylinders vice the side-to-side plates of the Deans).

Let me know what you think. Thanks!

Brett

p.s. I love the unit so far, so I am anxious to see a resolution.
