2AAB (DISA) but which?
So I have a recurring 2AAB. Is it DISA #1 or DISA #2?
I've been using protool for coding, pulling codes and reading data. It says #2 opens ~4500 and #1 opens closer to redline, maybe 5500 I didn't catch exactly when. That #1 opening sounds way too late to me. Unless maybe it's a delayed reading.. I thought one was for the low end approx 3k RPM? It's likely a false or delayed reading. I don't think it's possible to read the actual position, only what signal is being sent to the DISA. On shutdown, even with one unplugged both toggle from 70% to about 33% so I'd guess that's the correct output it is reading. Both DISAs are not original. The outer came without markings and a metal pin installed but I don't remember the vendor. I'm pretty sure it's working and is the ~4.5k RPM DISA. There is a fax machine sound on shut down which may be the large one, it's hard to pinpoint. I definitely feel like there's some power missing in the low end which would explain the code and the likely DISA failure code. On a side note, any good vendors or brands for a small DISA? They all seem to be double the price of a large, almost better off going OEM. Last edited by freakystyly; 06-26-2019 at 08:28 PM.. Reason: Clarity |
