Instrument Voltage Regulator

[Smedley]

All of my gauges pegged full on the way home this week. It freaked me out for a second when I saw the temp gauge fully pegged. I stumbled across a post on FB about a non stock instrument voltage regulator (IVR) on Amazon for $10, so I thought I would give it shot as replacements are quite a bit more. Link below for part. On Amazon I found a review with a picture from a Mustang guy that showed how he wired it. I got it today and wired it up. So far, it works as it should. I was even able to mount it to the stock location.

Will,
Being an electronics type guy I would say this should work fine but I didn't know the Bronco IVR was set at 6V. It is probably stable enough (voltage wise) that the readings won't change much based upon ambient temperature. For some reason I thought stock was closer to 8V but probably I am wrong. If the voltage is different then the readings may be proportionately higher or lower as the gauges measure current with the resistance provided by the sensor.

Thanks Jim. I will need to drive it a bit to see if the gauges are close to accurate. For now, they are not pegged.

FYI. Gauges are both inaccurate and inconsistent with this voltage regulator. Will upgrade to proper part. $10 mistake.

The stock IVR voltage is a pulsed rate of 5.5 volts. + or - a few 1/10’s, depending on the manufacturer. The voltage variance isn’t enough to change the accuracy of the gauges, certainly not as much as the resistance of an aging wiring harness.
