Re: [T3] Annoying electrical problem

[Per Lindgren <lindgre@online.no>]

<x-flowed>After having a look at the diagram, I would do as Bob sugested, check 
the dome light. In fact, take it out of the roof and disconnect it. And 
it must be something *after* the fuse, since anything before the fuse 
wouldnt pop it! Also, try to disconnect the wire from the fuse to the 
hazard switch and see if the problem is still there. If it is, you 
should examine the wires to see if there are any bare parts where they 
can get grounded.
