Not much to add
I'm still using my vintage 2007 3500 EFIS / EMS. Rob has offered to make me a good deal on a newer model, but this thing has been bullet proof for over 500 hours. For a vfr pilot and plane I just haven't been able to justify upgrading. I'm used to it and I like it. When glass panels started coming out I was very conscious and concerned of the almost immediate obsolescence factor in the electronics industry. So far I have resisted the newer bling in the interest of my retirement. Maybe someday...
Oh I did have to replace the internal coin battery during the condition inspection after 7 years when the unit started forgetting some of its settings and defaulting to the originals. Not a big deal at all. I think it cost 3 or 4 dollars locally at Walgreens and took less than 15 minutes to replace.And I had an EGT probe go bad about a week before Oshkosh. It lasted like 8 years. I was concerned I might not have it in time to install and flight test. Shoot, Jenny had it to me in about 2 days and I'm half way across the U.S. No special freight charges, either. Great people, great product, satisfied customer.
Have you tried powering the 3500 up on the bench? That will tell you if the problem is with the 3500 or some other issue in the Rv-7.I am just new owner of RV7 with an AF3500 EFIS. I left the master and I discharge the battery. I've charged the battery but I've got a problem with Plane power alternator wiht an intermitent charging problem and suddenly I've lost power on my EFIS and never come back. In the user manuel it said there is a diode protection but I don't know if that fail.
Is there anyone has found a similar problem with the AF3500 EFIS?
I am interrested indeed to this program but I guest my AF3500 has to be workable. I will call them Monday.Have you tried powering the 3500 up on the bench? That will tell you if the problem is with the 3500 or some other issue in the Rv-7.
while the older AFS screens just seem to keep on working, have you considered upgrading to a current model? If you weren’t aware, AFS has a nice trade in program. I traded in a 3400 last year after ten years in my RV-10. there are significant performance improvement, as well as running the current operating system there are all kinds of neat bells and whistles available to help reduce your workload in the cockpit.
That may be a bad assumption. Talk to Trisha or Jenny about the trade-in program. They don’t resell the units, they use them for parts to repair other units.I am interrested indeed to this program but I guest my AF3500 has to be workable. I will call them Monday.
In the pilot guide it said with relay protection diodes installed, the AFS screen can be turned on before the engine is started. I don't know if is installed. May be this diodes is burned.
Or may be there is one inside the unit to protect the circuit. By chance, to you have the schematic diagram of the unit?
Comparisons of avionics systems are always... interesting. Owners will report favorable experiences, but real comparisons across vendors don't seem to happen.
