If the fuse for the dash and tail lights keeps blowing on my 89 rx7 be causeded by a bad head light switch

 

still cant find any burnout at the switch i have read a lot of threads but still cant figure out what causing this fuse to blow can any one helpppppppp

 

There could be a problem w/the harness and not necessarily the switch. Does the fuse in question blow after the switch is turned to the first position? You might want to depin the Red/Black wire that supplies voltage to the tail lights and the Red/Green wire that supplies power to the dash lights and so on. Then turn the switch on and see if it blows. If it does then the fault lies within the switch or the White/Green wire which supplies voltage to the switch from the Illumination fuse. If on the otherhand the fuse does not blow then the problem lies within the R/B wire and or the R/G wire. Then repin one of these two wires and see if the fuse holds or not w/the switch turned on. If it does not then you isolated the problem to the wire which has not yet been repinned.

 

by the way i just replaced the gas tank and fuel pump right before this started happening

 

then go back and check all the wiring in and around your tank,tail section etc.
you could have hit something and pinched the wires..
Seems odd for stuff to happen after you did some repair,so it has to be related.

 

thanks for the info im not real good with electronics what do you mean by depin

 

Remove the wire and its connector from the plug.
