Alternator worries?

Seems like my leds in my gauges flickerand voltage is reading 12.5 under load. Time for a new alternator?

Have you checked power and ground connections?

There are several videos out there, here is one.

If, as shown in this video, you have after-market mechanically-connected battery cable terminals instead of the OEM cast-in-place connection, when cleaning the battery terminal-to-battery post connection, clean the cable connection(s) at the battery cable connection to the terminal. These are mechanical connections that are subject to poor installation and vibration, in addition to corrosion.

I do have some slight corrosion on one batt terminal. It's a brand new Optima battery

Also, you will find a ground connection for most of the dashboard along the bottom of the dashboard frame just to the right of the center console's connection to the bottom of the dashboard. Look for a green-colored screw.

I'll check that as well. It's weird when my alternator is pushing out 14 volts my oil pressure gauge is fine but when its pushing out 12 or below my oil pressure sits at "n" . Keep in mind I have a 96 cobra so my oil pressure gauge is a full sweep and not an idiot gauge.

Did you get this figured out?
