The Tuul Crib 7,332 #1 Posted September 11, 2018 I have gauges on my 520 I'm parting out and I'm wanting to make sure the gauges are in working order. Anyway to check these gauges? Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,499 #2 Posted September 11, 2018 Do you know the part numbers for them? The Demystification Guide may have a test procedure. If it does they should be in our manuals now under the part number. Garry Share this post Link to post Share on other sites
