GAJoe 844 #1 Posted November 5, 2022 (edited) I have an older 312-8 with the K series engine (buy is pending) that I hope to have home soon. (Sorry I don't have the model # yet.) I have seen one of these with the test switch and trouble lamps option (What is that commonly called?) but this one does not have it. I am pretty good at troubleshooting if I have the diagram so as soon as I get it home I will get the M#, S# and get the manuals and diagrams to have on hand. I was hoping to get familiar with the different safeties, their location (pictures would be great!), common problems of each, troubleshooting procedures, and replacement tips. Maybe this could be a reference thread for myself and others to visit when we can't remember this info. I searched for this but was unable to find such a thread. If it exists then let me know and I will delete this. Edited November 5, 2022 by GAJoe 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,046 #2 Posted November 5, 2022 Guessing you have a model 21-12K801 - the first year for the 312-8 which did not have the idiot lights. https://www.wheelhorseforum.com/search/?q=21-12K801&quick=1&type=downloads_file 3 1 Share this post Link to post Share on other sites
