I'm going to have to clarify your clarification Andrew! Only the small cars got the regulator built into the FUEL gauge starting in 1967, switched to the TEMP gauge in 1970. The big cars (including Javelin and Pacer) continued to use the separate CVR (constant voltage regulator). The small car regulator can be bypassed and an external solid state regulator used. I haven't done it myself, but have talked to others who did. It requires taking the gauge apart and jumping a wire over the old regulator or soldering the points closed so they no longer operate. Then 5V can be fed in. -------- Date: Fri, 29 Aug 2008 09:18:48 -0400 (EDT) From: adh@xxxxxxxxxxxxxxxxx (Sandwich Maker) Subject: Re: [Amc-list] Instrument Voltage regulator no gas/heat gauge on 66 Classic " From: Joe <jgray_55@xxxxxxxxx> " " I must of missed Tom's reply/fix???
