Week 4 (4/25-29) Cold Start System

We noticed a piece of equipment having a difficult time starting for the operators in the morning. We pulled it in the shop to check the starting system. We started with the glow plugs. I placed my meter on the glow plug railing and found a good ground. I found that I got no voltage to the railing. So I placed the meter on the first plug in the circuit, nothing. I then Attached my meter to the supply wire for the plugs and found a healthy 12.7V. I pulled the first glow plug in the circuit and switched my meter to ohms and found that it read a healthy OL on the screen. A new set of glow plugs later and it starts beautifully every time.
