[TR] Blowing Fuses

[Chip19474 at aol.com]

John,
 
I just helped a guy last week with the same problem in his MGB.....turned  
out to be a bad bulb that was grounding in one of his front parking light  
socket assemblies.  Here's what we did to trouble shoot: remove the  fuse and the 
red/green wire (spade) from the "red fuse" fuse position;  leave the red wires 
connected to the fuse position; set your multimeter to the  "buzz" setting 
(that's the position that sounds a buzzer in the meter  when the test leads are 
touched together); touch one test lead to the spade  connectors where the red 
wires are connected on the fuse box and touch the  other test lead to a good 
body ground or your battery ground since it's right  there; if the meter buzzes, 
you've got a confirmed short to  ground somewhere in the marker light circuit.
 
Now the fun part.....isolating the bad bulb or bad socket.  Leave  the fuse 
out; start with the nasty rear tailight sockets - they have a  reputation for 
getting funky; pull one socket out - check with meter  back at the fuse box for 
a "buzz"; repeat the buzz test for the next socket and  so on moving to the 
front parking lights.  I've never encountered an  electrical  problem with the 
side marker lamps so you can save them for  last in your process of 
elimination. 
 
Good luck....

I turn on the parking  lights.
