Thanks for the informative response! Idk why my pictures all uploaded the wrong direction.
Yes, that engine starts and immediately goes to its full running rpm and holds there. We test run it every Friday along with all our other equipment that’s not running every day. As the maintenance crew, we only hear about issues when the watch engineer can’t get a piece of equipment to run during the weekly test. Just finished up fluid change service on our 4 cylinder GM Detroit diesel that drives our fire pump on a similar skid.
What engine or what year should I look up when shopping for replacement distributor cap and wires?
