Constant Voltage Regulator 1965-1966

Product Description

Constant Voltage Regulator for 1965-1966 Mustangs.

This new constant voltage regulator features solid state technology for smooth gauge performance with no adjustment needed. Original units use mechanical contacts that open and close causing gauges to fluctuate needing to be adjusted manually with a screw driver.

When this part goes bad, it may cause one or more of the dash gauges to stop working properly. So when you are installing new dash gauges, you may want to replace that old regulator to prevent this from happening to you.

Constant Voltage Regulator 1965-1966 is rated 1.0 out of 5 by 1.
Rated 1 out of 5 by from Fell apart part When they say be careful with the part in the video, they were not kidding. One of the clips easily popped off when re-installing the gauges. When I tried to push it passed the brass head, the entire part came off the poorly mounted plate. I'll be much careful with the replacement.

Product Questions


my gas gauge works sort of. when full it reads very high, my oil pressure reads high and the temp reads high. but all gauges do work just high. could the CVR be the likely issue

Asked by: cmmisr833
It very well could be the problem.
