Location: Auckland, New Zealand.		On my 57 Fury, the voltage regulator has a radio condenser, the little steel cylindrical thing with one wire.
I bought it nos, and it is part number 1689592.
It has the little red paper tag on the wire, which reads "CAUTION. Connect to regulator battery terminal only".
A friend of mine has a 58 Fury, and his tag reads completely different. His reads "Connect to armature terminal only" and "Do not connect to field terminal" on the other side.
What is going on here....? The manual shows a picture of it connecting to the "ARM' terminal on the regulator also.
Does anybody else still have this little red paper tag on their radio condenser on the voltage regulator and if so where is yours attached?
Also, does anybody have a spare generator radio condenser in good condition that they could part with? Mine has a very dodgy wire.
Glenn.
57 Fury.

Location: Auckland, New Zealand.		...Like it says on my tag...but that just doesn't seem right to me. And in complete contradiction to the book's instructions. Thanks for your input. Has anybody else had a chance to look and see what their voltage regulator condenser is connected to?

Location: Auckland, New Zealand.		Yes there is a radio condenser on the generator and the coil also, but I am referring just to the one on the voltage regulator...

Location: Southern Sweden - Sturkö island		The condenser on the generator shall be connected to the ARM terminal ONLY. The condenser on the voltage regulator shall be connected to the ARM terminal ONLY. The ARM is short for armature, which is the coils in the generator, which is the greatest source for radio disturbances on the charging circuit.

Which leads me to belive that the condenser marked to be connected to BAT belongs to an alternator.......

Location: Auckland, New Zealand.		But an alternator has a built in regulator doesn't it? This tag clearly says "Connect to regulator battery terminal only". So it can't be for an alternator can it? I cannot believe that they screwed up the production of these tags far enough into production that they ended up labelled incorrectly on the shelves.... Sure is a mystery. I'm going to have to borrow someone's correct tag, copy it, and install it as you say-the way the manual shows it and not the way my tag says.

Location: New Castle PA		Here are the tags as I've reproduced them using Microsoft Publisher, with as nearly correct font and so forth as the originals. There should be a condensor on the regulator battery terminal for sure (tag is obvious), and one on the generator for sure saying "Connect to Armature Terminal only" on one side and "Do not connect to Field Terminal" of the tag. Then there is the separate "kiteshaped" red tag on the generator under the large terminal but NOT on the condenser wire. That tag needs to be cut along the lines drawn on the picture to get the correct shape, and then a hole punched through it as shown.

Glenn, the drawing in my DeSoto manual clearly shows the regulator condenser attached to the BAT terminal, unlike your diagram. And your friend's tag is for the condenser on the generator, NOT the one on the regulator.

Location: Auckland, New Zealand.		But that just contradicts what Wizard is saying above, what the book says, and what common sense says, regarding connecting the condenser wire to the battery terminal of the voltage regulator...? WTF....? You are incorrect about my friend's tag being for the generator and not the voltage regulator. It is part number correct for the voltage regulator, with the Mopar part number stamped on it, and anyway the generator condenser is a totally different shape, with the bracket attaching in the center of the condenser..... I wish I had taken better pictures of the buried Plymouth with 6 miles on the clock. That would surely confirm 100% one way or the other. Did anybody get better shots than these...?

Location: Southern Sweden - Sturkö island		The old alternators had external regulators as well. Now, it will be ok to install the condenser also on the BAT terminal of the regulator for a generator - but the effect will not be so good. The tension in the BAT cable will have a steady flow - more or less depending on the consumers, while the ARM cable will have pulses of tension - on and off or steady flow. There will be more "contact" noise from the ARM. In my '60 Chrysler, the condensors are connected to the ARM terminals on the generator and on the regulator and that is an OEM installation.

Location: New Castle PA		Glenn, I know that your friend's GENERATOR CONDENSER is a different shape than the REGULATOR CONDENSER. It's supposed to be. However, the TAG that says "Do not connect to field terminal" on one side and "Connect to armature terminal" on the other side is the tag that belongs on the GENERATOR condenser. Here's a scan from the 1957 DeSoto service manual.

Location: Southern Sweden - Sturkö island		So, that proves that there was a change somewhere from '57 to '60! Maybe they found out that mounting only a condenser on the generator will make the armature cable into an antennae for disturbances.

So, if you want to be period correct OEM, obviously the condenser shall be mounted on the BAT terminal on the regulator for the 1957 cars. If you want the better noise reduction and can accept this small deviation from OEM, mount it on the ARM terminal on the regulator.

The condenser on the generator is clearly the same mounting instructions for '57 (up to?) '60

Location: Auckland, New Zealand.		All.
I feel I have received final confirmation of this.
Regardless of what the (possibly incorrectly printed) red tag says, the factory service manual shows it connecting to the "ARM" terminal of the voltage regulator, and so it also was on the electrical system of the (6 miles on the clock, unrestored) buried Tulsa Plymouth.
Good enough for me.
Glenn.
