Alti II Stuck Needle
I tried to find an existing topic but couldn't.
My Alti II is getting stuck on the way to altitude - it's off by about 500ft to 1000ft before i 'knock it' and it pops straight up. I don't think it gets significantly stuck in FF, but I have nothing to compare it to apart from my audible.
First let me say that sending it back to Alti-2 for service is probably your best bet. They are good people and they provide excellent service.
Having said that it is pretty easy to open an Alti-II and clean the works with Naptha. Naptha doesn't leave a residue and that's a good thing when cleaning an altimeter. If you choose to do this I highly recommend that you find someone (probably a rigger) with a test chamber so you can exercise the device after cleaning it and compare it to a properly functioning unit.
Considering this is a piece of equipment that can directly impact your safety sending it to Alti-2 really is the best thing to do. Ask yourself this: How comfortable will you be with an altimeter you've serviced yourself?
