After getting warmed up, my alternator and brake warning lights come on and flash off intermittantly. They seem to stay off for longer periods when I'm idling. Even when they are not flashing on/off, I can see from the headlight output that there is intermittant dropping of electrical. Also, my speed control stops working when the warning lights start coming on.
Replaced the alternator recently when the reverse happened - the lights came on when cold and went off when warmed up.
When I had the system checked (after alt replacement) for this recent (warmed) issue, the guy said there was too much "noise" in the system for him to read the alternator output.
This is a 1990 Camry V6.
Thoughts fellas??
