Your mechanic is correct. It does deliver 12 Volts to the rear glow plug (the first in the series), but, since they are wired in series, only the last one (the front) is hooked directly to ground, therefore, none of them get the full twelve volts. I hope an electrical engineer or such will explain the difference between series and parallel as it applies to resistors which is really what glow plugs are. I left the indicator in the circuit. It is important to do this since it is also in series and would raise the individual voltages and cause premature burnout. I didn't have to clean the precombustion chambers on mine, but I did on a 424 several years ago. We already had the head off so it was no problem. I'vegot an extra head in the shop. If you will Email me Monday to remind me (dorisholtman@aol.com) I will be glad to check the glow plug deal out for you and the pre combustion chambers. Good luck.

I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
