1975 300D Glow Plugs
Car would not start so I tested my glow plugs and wires through the relay plug. 3 tested fine, 1 tested open, and 1 tested at 22.5 ohms. The 1 that tested open was 2nd in line from the firewall. I swapped it with the 1 in the first position from the radiator and now the car starts with no problem even though I have one bad glow plug. Any thoughts on why this is working.
Also, do I need to be worried about the one that tested at 22.5 ohms. Any info would be appreciated, thanks.
