68 mustang IVR
 

Well I got most of my lights working. The problem was both bad grounds and a short in the rear wiring harness. Problem now is my dash light dont work. My turn signals work and the 4 way flashers work and thats all. I checked for continuity fron the light switch to the connector OK. I do find that at the constant voltage regulator with the lead wire off I have about 5-5.5 volts on the lead wire. On the other side of this with the connector off I have only 1.28v at the terminal. Does this sound right? Is there a sure way of checking this IVR? Help would be appreciated.

Regards

Steve
