How to get this out? Wires broken at the under spark plug loop.
Guess I could just cut it and pull it out, but how do I get the new one in? If I loosen a bunch of the screws that hold the engine tin on, would that get me enough space to get the new sensor to the spark plug? OR is there some better way to do this? Thanks for the advice. Ed  |

Then this is a different story. That sensor is most probably a type K thermocouple where the positive wire (yellow) is nickel-chromium (chromel) and the negative wire (red) is aluminum chromium (alumel). You will want this wire to go all the way to your gauge, do not switch to regular copper wire throughout its length.
The spark plug rings thermocouples are available at the Sensor Connection where you can configure it. https://thesensorconnection.com/product/typ...nal-type?v=2378 As for the engine tin, you should be able to remove the thermocouple ring by removing the spark plug. Problem might be where the wire is fished through. This is not a stock installation and therefore could have been done many ways. Hope this helps a little. (IMG:style_emoticons/default/smash.gif) |
