Hello

I was driving down the road and my alternator light comes on. So I go to the local parts store they put it on their machine and it says that my battery is good and my charging system is working properly. When the alternator light came on my turn signals and my engine temperature gage both quit working. I have looked at all the wiring in the engine compartment and as far as I can tell everything seems to be in order, nothing apparently broken disconnected or chafed.

Anyone have any ideas on what's going on here.

Thanks

I suggested the issue might be the fusible links on one of your other threads.
I did forget to mention that when a fusible link blows, sometimes you cannot tell because the outside of the wire doesn't melt, so you have to feel the wire to see if it is soft inside(bad), or if you can feel the wire inside(good).
The only way to tell for sure is to disconnect the plugs from the wiring harness leaving it plugged onto the battery, then using a volt meter, check for power on all 4 wires.
