Your welcome. Glad to be of help.I have had plenty of help on this site. What goes around comes around. Its great when you can fix it yourself. Better to have the cash in your pocket .
I had a case on my Mustang with the fuel gauge, oil pressure gauge and temp gauge all working for 5 minutes on, then 15off, then 5 on, then off again.
AS these gauges are 6v in a 12 volt system i used an electronic 12v to 6v electronic regulator to run 3 gauges. You need 1 electronic reculator per gauge. The reg would heat up and cut out under overload, cool down and then function normally again.
Bootom line; 1 reg per 6v gauge for old Mustangs with 6v gauges.
