I was up in the mountains driving around, and i looked down at my dash and my check battery light was on. My gas gauge was not working, as well as my temp gauge. come to find out.. my blinkers didnt work either. my hazards work and my headlights work. I am pretty sure my ALT. is going out. but could this cause my dash problems?
It is an 87 toyota single cab. any help would be grately appreciated. thank you.

 

replaced alternater... nothing changed
