If the fuse blows immediately without the lights being turned on, the
solution should be obvious. If the lights must be turned on for the fuse to
blow, it is time to start isolating the various branches of the system. That
you can predict when the fuse will blow should be of immense help in the
Electrical matters are easily the least understood part of automobile
systems. It is imperative to find a tech with a good grasp of electrical
diagnosis in order to reduce the diagnostic time and effect a timely and
Well it was only a matter of time before dogbreath showed up.... The test
light is an inappropriate tool for this task since relativel low current
flow will have the ligh shining brightly. Substituting an old sealed beam
headlamp will work very well.
All the same, to reduce diagnostic time, isolating circuit branches will
narrow the area and result in a more timely diagnotic process.....
OK, bowser... insert your ritual grunting here....

You likely have a short. Finding the cause will not be easy. You need a
wiring diagram. Go through the circuit patiently using an ohm meter
looking for the source of it. It could be a piece of electronic equipment
that is malfunctioning, or a simple short to ground due to frayed
wiring, etc. Do not use a higher current fuse!
FYI, faults like this are why cars have fuses. Fuses save the wiring!
