RE: IML: 73 in the dark

["Robin Giesbrecht" <robings@xxxxxxxxxxx>]

If your headlights are working then your battery feed to the fusebox should 
be ok.This comes through a disconnect and a fusible link and then through 
pin 9 on the bulkhead disconnect.That is where the headlights picks up it's 
power from. You have two busbars(battery and accessory and each has their 
separate feed) in the fusebox from which the power is distributed. Sounds 
like your accessory feed is dead and this is coming through the ignition 
switch. The battery feed for this is through a disconnect, a fusible link 
and then pin 13 on the bulkhead disconnect. Then it goes to the ignition 
switch through a rectangular white plastic connector under the steering 
column. And then from the ignition switch to the fuse box. Note these power 
sources originate in the engine compartment at the same place but go through 
separate fusible links and different pins on the bukhead disconnect. I would 
pull that bulkhead disconnect off and look real close at the condition of 
those pins or wahtever you want to call the contacts. I have had them burn 
right off due to high resistance caused by corrosion. Use a meter and check 
for voltage here. Another trouble spot is the white plastic disconnect under 
the steering column. Same thing. My 72 nearly went up in flames because of a 
high resistance in this connector. I have been looking at a 1972 manual and 
I would think the 73 should be very similar if not the same.
