DST800 Test Plan

[RickSegal]

Greetings,

I wanted to see if this plan is 'doable' and I'm thinking about this correctly. Because I live on North Vancouver Island with no Raymarine support, I have to be pretty precise in my troubleshooting before sending parts out. I have a problem with depth reading coming from the DST800. I have an ITC-5, i70, and an a95 MFD.

To figure out if the DST is bad or there's a problem with the ITC-5, I'm proposing these actions:

1. Disconnect the DST800 from the ITC-5
2. Wire it directly to the i70.
3. Test it.

If good depth, transducer is go, chase ITC-5 or other problem. Bad/sporadic reading, replace the 800.

Does this sound right? And, before I attack the boat, can the above be done?

Thanks,

Rick Segal
