The problem is that any resistor you add will reduce the working range/ sensitivity of the gauge. Here’s the formula, you can see for yourself. R1 can represent your sender resistance extremes, R2 can be any random parallel resistor, Req = the resistance that circuit “sees”.

Req = (R1xR2)/(R1+R2)

I don’t believe your plan to add a resistor will work very well. You may get some needle movement, but it won’t cover the entire gage range. If you add a 100 ohm resistor in parallel (series won’t work at all) to your 80 - 198 ohm sender, your new effective resistance range will only be 44 to 64 ohm...

Tony, you’ll need grade 8 bolts for that much torque.

May I suggest “Elsa” [Lanchester]? She was was the lead actress in one of favorite movies, Bride of Frankenstein.

Betty and Veronica!

Man, if there was a contest for best car names, you are the winner!

Does this suggest Frankenstein may be put out to pasture?

I don’t know how long the new battery has been waiting, but lead-acid will self discharge at like 3 - 5% per month, so be prepared.

According to Mark 11 enterprises the sending unit for a 57 lincoln is extremely rare and they can't locate one.Might have to add resistors to make it work properly This topic may be helpful. I am thinking that it may be possible to rivet or in some manner attach a Ford sender to the Lincoln 6 bolt ...

And thank you for that!

I don’t know if this might not be helpful in visualizing what’s going on.

If your sending unit is original, and is giving smooth and steady resistance readings throughout the range of travel, then I'd say it is correct. I don't believe the manual mentions the specific resistance. If you (very briefly) short the wire at the sender to a good ground, does the gauge then move...

Your memory is good, Tony:

At least for 1968, my Cougar manual called out substituting a 10 ohm resistor for full, and 73 ohms for empty. I'll bet that worked across the board.

At least on my '62, the common problem is that the motor whirs, but nothing happens because the solenoids get sticky and won't pull in. I rarely change the seat position, so it really wasn't a big deal to whack it with the palm of my hand if I ever needed to do it. I redid the upholstery maybe 8 yea...

I really like that red and white combination, bimmerkar.

That Palomar blue looks great contrasted against a pink dinosaur!
