[TG] [TG11] autopilot affecting MFD

[Tom - Raymarine - Moderator]

Hello Guy,

That is indeed a very unusual problem. I've not come across anything quite like it.

Do you lose all chart detail on the eS, as if the chart card has been completely removed?
What shows on the sonar image when you lose the depth data?
Do you think you might be able to do a split-screen chart and sonar page and then video exactly what happens and post that video back here?

The only link that I can see at this moment is supply voltage: when the pilot's engaged it obviously draws more current, which will inevitably pull down the electronics supply voltage. In electronic systems you can get a range of unpredictable problems when the system is power-starved, and I can certainly see that the sounder might be one of the parts of the system affected first as it consumes a reasonable amount of current itself. I'm not saying that your battery voltage is low, but rather that you *may* have a voltage dip at the common connection point of the eS and pilot (distribution panel?).

Regards,
Tom
