digger, jeep, o1951 (I'm a 1953 model year myself) you guys pump me up! I found that taking off the air cleaner assembly makes it all easier to get to. ****! I just got finished putting in a new whistler turbo two months ago. Brutus was running sweeter than a brand new Toyota. Was driving him to work two or three times a week and then this. I will get to the bottom of it. Can't stand not getting my daily open windshield facial. I smell an Erik's order coming up. o1951.....heavy duty marine Detroit Diesel start button is on the way. Yes, I should check for a short, but hey I've been up for 25 hours now. Be well my friends and I will keep you informed. Thanks for caring enough to ask and for your suggestions.
