Re: [Chrysler300] temp gauge sender question

John and All

I did not see as of yet any response from the more knowledgeable re: your 
quest for info on temp senders.

For example the difference between 57 to 59 and 60 to 63 I sell is the ohms 
it pulls as it heats up. When cold the ohms is low.
When at temp it pulls more. When hot it pulls more. The net effect the ohms 
is what makes the temp needle move based on the temp.
If the mfg changes the gauge then they have to change the ohm draw to 
correspond.
That is my simplistic answer. Maybe some with more knowledge can add to 
that or correct me.
I do know the senders I stock have different ohm ratings.
