Title: Blowing fuse #5
Post by: Turbocoupe on August 05, 2018, 10:02:15 PM
Hello group need some help on an elictrical problem. Lately at turning on ignition key to on the #5 fuse blows and there for no turn signal. So I have a short some we’re. Only thing I’ve able to find is when doing a voltage check on fuse box I came across fuse #8 dropping in voltage when removing fuse. So it makes me think the blowing of fuse is do to a circuit in fuse #8. The internet has help me find some of these circuits but can seem to locate key warning, illuminated entry, keyless entry, power door lock relays, anti-theft, courtesy lamps, cluster memory. Any help on a site to find these.

fuse 8 seems like a convenient wire for someone to find "power" to wire something else in.

your going to need one of these,, prob 15A will be fine.
I use these pretty often to avoid using up fuses.
this kind of thing is what they were made to do anyway so why not?

replace your fuse 5 with a resetable circuit breaker fuse.

unplug one item at a time associated with fuse 5.
when the breaker stops tripping, report back, this will isolate down to which branch circuit is the fault off fuse 5.

perhaps use two for fuse 5 and 8.

And remember not to be tempted to try higher rated fuses.  A fuse's job is to protect the wiring, not the load, so a larger fuse might be able to carry more current than the circuit (turning the circuit into the fuse).
