Dash Cluster Question - 68 Barracuda

also used the battery charger to test. But ended up rewiring the whole car, didn`t want 49 yr old wiring in it. Also bought a limiter off ebay and a new sender. It works , but is slow as molasses getting there ! ???

Yep, A regulator that can output nothing more than 5.4 volt and 1.5 amp once heated up, puts out a little less than that when stone cold. Does make for very slow needles, especially when running 3 instruments. No more rapid temp changes could extend the life of the gauges, in theory, not proven.
The RTE unit does mimic the mechanical limiter in rapidly heating the gauges/moving the needles at switch on.
I've got my 67 rally panel out now and I am considering a separate 7805 regulator for each of the 3 gauges. Hung up on where to put them, designing and building a home for the little devils. LOL
