Hello

The first plug burns anyway... everything is/seems ok in the circuit in serie...

thanks

My Manual Glow Plug Start Knob... have a screw but haven't the wired from the screw that you can see in the photo.

I don't want to brun another glow plug!!! Help. Please

thanks

The only way a glow plug can burn out is that you're passing too much current through it. You have a short to ground somewhere OR you don't have the series resistor links installed. The wiggly wires between glow plugs are very important, if they've been bypassed with wire, you will burn out your glow plugs quickly.

If the first glow plug in the circuit is the one that keeps burning out, you have a short circuit somewhere in the glow plug chain, likely between it and the next plug. If you have all 4 plugs in series, you have ~3V across each plug. If you have a short to ground between the first and second plug, you're placing 12V across that first plug. It will rapidly fail.

Another possibility of failure is a bad injector on that cylinder. If you have a poor spray pattern, it can act like a cutting torch and burn that sucker out in a heartbeat.

I will have to check that.

Thanks again

Hello

I had a short to groud. Part of the problem solve, I have clean the houses of the plugs, now the first plug don't burn, even if there is to much voltage in the circuit, and the plugs are heating too fast, or maybe is now psicologic fear of burning another plug. I have too check the voltage between.
