440-4spd. I used a better light and my reading glasses and do see the four screws on each side. That makes sense now.
On mine, fuse blew every time I hit the brake pedalIs the fuse element actually blowing or is the end in the cap melting..
2 different problems with the same outcome.
This is what I do also. But I use a new small headlamp bulb, have enough wire to hang it from rear view mirror so easy to see. Also don’t want bulb touching anything it could melt. When there is no short, power going through will show as dim light as well as others in circuit. When short present will be full brilliance.Get a socket for a 1157 bulb and solder on some clip leads. Clip the bulb across the fuse socket that keeps blowing. Now if the circuit is going to blow the fuse the bulb will glow BRIGHT. Now disconnect items starting at the taillights and move up the harness until the blub stops glowing. Perform the wiggle test as you go while looking at the blub. You may need to jump the brake lamp switch as you troubleshoot down the paths.
Keep in mind tail lamp sockets themselves can short. The coil springs on the bulb contacts can crack/break and intermittently short to ground.
It might be worth lifting the rear seat also - the loom passes close to the framework of the seat - and a pinched wire could be hiding anywhere really.Roger that. Will go after that next. Since the turn signal switch is in this chain, dash signal light bulbs would be in there as well would they not? Or maybe the switch has to be activated to pick up those bulbs and change the OHM reading. If those are included then the dash would have to come out. I may have to do that anyway to get the EL function working or cluster sent out for repair. Have not checked the power supply yet since I have been on this mission.
