I need a little more info about your setup. It sounds like you have autometer gauges. Do you also have aftermarket turn signal indicators?

I'm assuming you have a stock fuse block. You need to take some voltage readings at various locations to see what is happen.

First run a clean ground back to the battery to make sure that is not the issue.

get voltage readings with the headlights on and off.

1. voltage at battery and altenator. Let's make sure the charging system is keeping up.
2. find the dash light connector on the fuse block and get voltages from there.
3. Voltages at the blinker flasher.
4. Voltages at the turn signal indicator lights.
5. Voltages at the blinkers.
