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?
Perhaps what he's trying to say is that any warranty will be voided and any damage to the unit during the attempted repair could be expensive to fix. If that's what he's trying to say, he is correct.
I once unscrewed the plastic lens on my Altimaster to replace it with a new, unscratched one. As the last of the threads came off the lens jumped sideways on me and sheared off the needle. I sent it in for a repair, but it was considered unrepairable. It was junk. Sure had a nice pretty lens, though. I had to buy a new altimeter.
So if you try this, proceed with caution, and be aware of the possible consequences. Trying to save a little money, can cost you a lot of money.
