Gauge temperature sender

[jabborabbo]

Okay, I bought an alleged gauge temp sender from LMC...threaded it into the lower t-stat housing and recorded the following temperatures (using an IR thermometer on the housing) and resistances using an ohmmeter between the connector post and the base of the sender:

Degrees. Resistance

195. 120

180. 147

150. 221

129. 285

99. 400

Now, from this site:

http://forum.73-87chevytrucks.com/sm...?topic=25339.0

the specs for the 67-72 temp gauge are:

Cold. 350 Ω
Operating temp. 76 Ω
Hot. 51 Ω

I've checked several temp gauges that I have and they all check out according to those specs, which means that the sender I installed ain't gonna work with any of my gauge clusters...so....

Where can I get a temp sender that has the right specs?????

Are you using Teflon tape? Never mind the edit, you have an I6, right? That info is helpful along with any mods you have done. Aluminum crossing brass crossing cast iron has different resistance.

It's an I6 - I didn't use teflon tape and in fact measured the resistance between the base of the sender and the connector post of the sender to make sure nothing else was affecting the reading.

No other mods to speak of....

Anybody?

I just bought a correct sender from a company called "Lectric Limited". They specialize in older vehicles. It fixed my gauge problems.
