68 dodge charger volt limiter for gauge cluster
 

was troubleshooting my gauges, all 3 arnt working, noticed that the wire going from the capacitor to the voltage limiter has fallen off. How and where does this wire connect to the voltage limiter, and should I solder it.


thanks

The cap is for radio supression, and is not part of the operation of the limiter per se

Some of what I found on my Dart.........

Pins broken / loose on the PC harness connector. Solder, repair, etc

The springy contacts for the limiter were not actually making solid contact with the board traces. Solder jumpers across

Replace the IVR with a good solid state unit. If you are confident, you can build your own 5V regulator. There are many examples on the www

Loosen / tighten the gauge stud nuts several times, and consider replacing with "real" nuts.

Mock up the cluster and check the gauges. The old Mopar gauge tool had three resistors

L = 73.7 Ohms (empty)
M = 23.0 Ohms (1/2)
H = 10.2 Ohms (full)

For example, you can go to RadioShack and buy a four pack of 100 ohm, 1/2 watt resistors. Wire all 4 in parallel, which gives you 25 ohms. This you put in place of the sender to ground, leave the gauges "on" for a minute, and each gauge in turn should give you 1/2 scale

Last, the grounding for these clusters is mostly luck. Attach a ground pigtail to the board, and bolt to the column support

The wire should have a 90* spade that piggy backs into the board with the limiter, it looks like it's right where it should be in the photo.

If that cap is shorted the limiter will blow !!!!
