New voltage limiter questions - 67 Dart 270
I can't imagine what this "small glued wire" is. The one you bought appears to be an original type replacement, meaning, it's electro--mechanical. If it works, "fine." Many of us bought solid state replacements. I got mine from RTE engineering. Don't worry about the extra prong. I believe it's for connecting a radio noise suppression cap on some models.
There are several things you need to be aware of and check and do if need be
This is a good thread:
Printed circuit pins repair
1....All of these cars ground the cluster "by accident" through the mounting screws. Good idea to attach a ground pigtail to the pc board mounting screws and run over and bolt to the column support or dash frame
2....Check the harness connector pins carefully for looseness, and clean and solder them
3....Check the resistance between the springy fingers which form the connector for the IVR. On my car, and in the thread above, you have to solder jumpers across to the PC board, as they lose contact
4....Loosen/ tighten the gauge stud nuts several times to 'scrub' them. Consider replacing the nuts
You can check gauges for accuracy by getting resistors, or a variable resistor, and setting to the check points re: the factory gauge check tool. There's several old threads on here about that:
Hey Del, Look what I found!!! An original Miller Gauge tester!!!
Below is a photo of one of the Mopar testers. The figures in yellow were added by someone, these are the check points for the tester, which you substitute for the gauge senders
