92 4Runner warning lights flashing

[tlcain]

my 92 4runner sparadically flashes the brake, battery, and A/T temp lights all at the same time. If the heater and headlights are on thre is a surge in power (heater blows harder, headlights get brighter) sometimes it lasts a second, sometimes a few minutes.

Sounds like your alternator might be full fielding (putting out like 16-18 volts)

I believe that year should have a internal regulator....you could probably take it out and get it tested at a Shucks or Napa or etc. :banana:

Maybe check the ATF while you are at it....

Manual here...
