A few minor electrical questions (68 Barracuda Dash).

A few minor electrical questions (68 Barracuda Dash).

So over the years my car has sat, allot. After I got it up on it's feet again I decided to touch up the electrical with a good cleaning.

I have cleaned grounds, connectors, changed bulbs, replaced the headlight and dimmer switch. (Surprising how beautifully the dash is illuminated with clean connections, polished lenses and new bulbs).

I do have some questions.

1)...My left turn indicator does not light up on my dash. The exterior turn signals DO work just fine. I have used my test light on the connector that would feed the pin that goes to the dash indicator light. I do not have power there and am having trouble following where this power would come from, using the service manual wiring diagram.

2)...My oil pressure gauge shows slight pressure (moves to first thin hash mark) with the key in the "ON" position. Works normally with the car running (verified against a mechanical gauge).

Is this an indicator of a problem or a calibration issue with the factory gauge?
