bulldogrider Posted June 30, 2011 Share Posted June 30, 2011 I noticed when the truck is cold they don't come on and I noticed only the engine oil tem gauge gets to about 150F the lights come on. I don't know how to read codes and what do I need to read them, it's a 1993 ch613 mack. And by the way soon the truck cools down the lights go off any help will be appreciated.
