[alfa] RE: ignition switch

[Gilbert Gagne <gilgagne@xxxxxxxxxxxxx>]

To troubleshoot the ignition switch you will need either a voltmeter or 
a 12 volt test lamp. Your local auto parts store has some small light 
fixtures with pig-tail wires useful for this purpose. Ground one of 
the pig-tail wires and use the other wire as a test probe. Now the 
problem: upper terminals 1-5 of the fuse box(numbered from the left) 
always have +12 volts. Confirm this by touching the test probe to 
each of the lower terminals and see the bulb light. No light means a 
blown or corroded fuse. 
Next, turn the ignition switch to "ON". This will send +12 volts to
upper
fuse terminals 6,7,&8 if the ignition switch is good. Test each of the
lower terminals to verify all fuses good. You may just have an inter-
mittent corroded fuse. If necessary, flip the ign switch "ON" several
times to verify that it always works while holding the test probe to
upper fuse terminal 6. This procedure should verify if the ignition
switch is good or not.

Good luck!
