Fuse 8 in 1986 22R 4x2 Manual

Hi All -- was driving to work yesterday and my alternator light came on, gauges stopped working, and turn signals stopped working. I went and had the alternator tested at the shop and they said I need a new one. Put it in, but the problem didn't go away. So, I started checking fuses -- fuse 8 (15A, driver kick panel) was blown. So, drove back to the store, bought some fuses, and the problem went away. Driving to work this morning, same thing happens -- alternator light, no gauges, no turn signals. Any advice on troubleshooting this electrical problem? Why would I keep blowing this fuse?



Thanks in advance.



Matt

The fuse keeps blowing because something is drawing too much current.

Some of the things on that fuse include the inst panel, power windows, ECT ECM, b/u loghts, PS ECM, light reminder ckt.

Indeed.



My truck is stripped pretty bare -- no power anything. As best I can tell, the only things I have on that fuse are gauges, turn signals, reverse lights, and discharge indicator. I have not been able to identify which of these is causing it -- e.g., the fuse doesn't consistently blow very time I use the turn signal. Imsuspect a short, but don't have a good idea about how to track it down.
