E-Body Solid State Limiter IVR3 Style Mopar part#2209216
The only solid state replacement limiter available that completely duplicates all of the OEM limiter's functions.
- Our limiter exactly duplicates the original limiters function by slowly switching 12V on and off.
- Our limiter has a built in polyfuse which protects the limiter and your wiring from short circuits on the output of the limtier
- Our limiter constantly looks for short circuits on the output of the limiter and will switch itself off if a short circuit is detected. When the short is removed, then the limiter starts working again.
- Our limiter has a built in diagnostic LED that blinks when the limiter is on, helping you see that you have power to your dash and that the limiter is operating properly.
- Our limiter has a warm up time at turn on, same as the original mechanical limiter. This means that your gauges will come up to the proper reading very quickly.
- Our limiter is always outputting a constant 5V average, no matter what the input voltage is (Within the range of 9V to 18V). If the input voltage goes too high or too low, then the limiter shuts off.
- Our limiter output is constant regardless of temperature.
- Our limiter is not sensitive to mechanical vibration.
- If our limiter loses ground, it will shut itself off. Contrast this to the mechanical and linear limiters, which will put out 12V and fry your gauges.
- Made 100% in the USA

[edit]
Advantages of our limiter over mechanical limiters:
- Won't fry your gauges when ground is lost
- No mechanical moving parts to wear out
- No points to stick closed
- No nichrome wire to break and then fry your gauges
- Insensitive to heat and cold
- Solid state so should last a very long time
- Short circuit protected
- Diagnostic LED built in
- Uses less current than the original limiter (because there is no heater wire)
- Original mechanical limiters tend to vibrate badly and lose regulation temporarily when going over very rough roads.
[edit]
Advantages of our limiter over linear home made limiters:
- Won't fry your gauges when ground is lost
- Doesn't generate any heat (linear regulators make a lot of heat)
- Has a warm up period when turned on to make the gauges come up fast
- Diagnostic LED built in
- Uses a lot less power (Linear regulators can waste up to 8W of power in this application)
