So will the soldering of the lead cause or change the operating resistance ?
I will replace it but I need to get it going & over memorial day WE I aint gonna find one. (IMG:style_emoticons/default/confused24.gif) |

Not an electrical engineer, but I think you will be safe. the range in ohms of the CHT is pretty large, like <99-3200 . so an added resistance of an ohm or two should NOT make much difference.

(IMG:style_emoticons/default/confused24.gif) I think you will be ok if you are going copper to copper. The voltages from the thermocouples are in the microvolt range as I recall, so it doesn’t pay to add resistance. |

CHT ? CHT??
Are we talking about the one screwed in the head near #3 chamber, or we talking about one that screws under a spark plug. the spark plug ones are thermocouples but I'm not sure if the #3chamber are TC's or a different thermistor device. Experts needed. |

that's what I do! Group: Members Posts: 20,065 Joined: 27-December 02 From: Port Hope, Ontario Member No.: 26 Region Association: Canada |
Crimp only.
I did this with the VDO on my bug because the plugs are 12mm, works perfectly...for a VDO. |
